Little Professor Dialog

Go To

Kids that speak by throwing around big words that you'd usually find in scientific journals or old English texts. This is either an indicator of the kid being a Child Prodigy or trying to simply sound like one. Often combined with Sesquipedalian Loquaciousness or Expospeak Gag.

This might be because the character is Wise Beyond Their Years or acts their intellectual age. See also From the Mouths of Babes and Most Writers Are Adults. Contrast Totally Radical. The Brainy Baby and Teen Genius are likely to talk this way. Subtrope of TV Genius. In a work where the writer has no understanding of children whatsoever, this can coexist with its opposite, Kiddie Kid.

Can be Truth in Television to an extent; kids can quickly pick up quite complex phrases and even the appropriate time to use them, without necessarily being sure what they mean.

  • Used in the E-Trade commercials featuring a baby that apparently knows more about investing money than most adults. This is Played for Laughs and not intended to be taken seriously.
    "Just a man and his thoughts. [Beat] And his iPhone. With an E-Trade app."
  • A Dutch advert for a supermarket chain has science tidbits trading cards or something similar. A cop pulls over these two guys in a car saying "Well you nearly went the speed of light, didn't you?" in comes a kid in the backseat explaining exactly how fast the speed of light is compared to the vehicle. The officer, flabbergasted, says, "I'll let you off this one time." Kid replies, "I'll do the same, then."

    Anime & Manga 
  • Kyon from Haruhi Suzumiya. The offhand math references, the science, the multi-cultural references, ancient philosophy, history, phonetics. All from a supposedly average High School Student. Top that with how his choice of words and terminology even in casual dialogue, in Japanese, makes him sound like someone in their 50s. Then again he is telling the story in the past tense... That, and Kyon is heavily hinted to be much, much smarter than he lets on, occasionally. After all, he did solve the Remote Island Incident with little help.

    Comic Books 
  • Features heavily in PS238, mostly from children who are Wise Beyond Their Years such as Zodon, Victor, and Tom (Murphy may or may not count — as a child, that is). USA Patriot and American Eagle also do this a lot, though much of what they're saying sounds more like rehearsed talking points than things they've come up with on their own. Most of the kids avert it, however.
  • Inverted, straightened, riffed upon, and generally explored in the Mad Magazine article "How to Rewrite Your Way to a PHD."
  • The Chick Tracts occasionally slip into this with his, with small children (surely no more than eight years old) knowing waaaaay too much about the Bible. And actively preaching. It is true that kids from religious homes will probably have some Biblical knowledge, but they're much more likely to say something along the lines of "Jesus is my friend!" in everyday conversation than "The substitutional atonement doctrine explains why the incarnation of Christ was necessary for mankind's redemption."

    Comic Strips 
  • Peanuts arguably pioneered this trope, between Charlie Brown's expositions on his anxieties, Linus quoting various authors & philosophers, and of course Lucy and her "Psychiatric Help" booth.
  • Calvin and Hobbes features allegedly six-year-old Calvin, who doesn't talk like any six-, or even twelve-, year-old that most of us have ever met. Bill Watterson sometimes lampshaded this by having Calvin follow up a spate of Little Professor Dialog with a more typical six-year-old reaction. The whole joke of about one-third of the strips is Calvin expressing a stupid idea natural to a six-year-old with the language of an adult. For example, when he justifies spending an afternoon collecting frogs by saying: "I must obey the inscrutable exhortations of my soul."
  • In Non Sequitur, Danae embodies this trope to a tee, but with an alarmingly good justification. She largely bases her assumptions on what is acceptable social behavior by watching politicians and pundits on television. When she emulates them, she'll use the words pretty much the same way they do — to make a bizarre political point. In spite of the fact that she only uses very basic mimicry to develop her points, she is still able to gain think-tank funding and cable news time because her arguments end up indistinguishable from legitimate pundits — even though her thesis is usually something ridiculous like "boys are boogerbrains".
  • The Argentinian comic strip Mafalda was published and set during the Cold War and revolved around the title character, a little girl (5 years old at the start of the comic, though she aged in real time) who was deeply concerned about humanity and world peace, and would comment at length about the geo-political situation at the time. Her friends, while not concerned about politics, would also frequently talk like adults. However, Mafalda was the most extreme case and often lampshaded at times, such as her parents occasionally telling her to worry about things "her own age" and her friends occasionally tiring of her musing.
  • A Dilbert comic portrayed the title character as a child trying to get permission to skateboard near a construction site. When his mom brought up the "Jump Off a Bridge" Rebuttal, he replied "Well, that would depend on many factors, including height, training, and equipment. But if 100% of the people who jumped off cliffs said they enjoyed it, as in my skateboard example, then I would conclude that it was safe. A better question might have been, 'If everyone wore clothes, would you do that?'" Rule of Funny, of course.
  • Frazz regularly employs 5-9-year-old students more intelligent than most adults. The other main character aside from Frazz himself, the irresistible Caulfield, plays a bored genius who has read more books in a month than most adults do a year and spouts observations about life and culture like nobody's business. Every other student Frazz gets to know likewise seem to carry inexplicable wisdom that, if only put into the hands of their administrators, would probably fix many of America's public education problems.
  • Cul-de-sac:
    • Ernesto looks like a pint-size Latino John Hodgman, and it carries over into the way he talks.
    • Alice and the other preschool children aren't always this advanced, but their vocabularies and speech patterns are pretty elaborate for their age. They can play this trope totally straight as well, such as when Alice describes one of her paintings as "post-expressionistic imagery of power, innocence, and repression."
  • The Brilliant Mind Of Edison Lee is about a six-year-old who fancies himself a scientist. Of course it plays this trope straight. Sometimes it reads like they're trying, and failing, to recapture the popularity of Calvin And Hobbes.
  • Phoebe and Her Unicorn Phoebe describes a story she wrote as "semiautobiographical".
  • Eight-year-old Thandi of Madam & Eve regularly speaks with an adult-level vocabulary.

    Fan Works 
  • In the Discworld continuum where Ponder Stibbons is married with children, his youngest daughter Ruth can talk like this. However, as she is truly a Child Prodigy and also has a practical intelligence inherited from her Assassin mother, Ruth has learnt to tone it down to what she describes as talking-to-parents, so as to get her ideas across more simply.
  • In Dragon Ball Z Abridged, Son Gohan can speak like this, to the point of Sesquipedalian Loquaciousness, since he's a Child Prodigy who's mastered theoretical physics ("although at this point I guess it's just 'physics'") before hitting puberty. On the other hand, piss him off and he can devolve into Hulk Speak.
  • Dungeon Keeper Ami has Keeper Mercury constantly explaining her scientific and magical discoveries with accurate and advanced words. She often realizes that her employees aren't as intelligent as her, and has no qualms repeating herself with "words that even Usagi would understand."
  • Sword Art Online Abridged has Yui who, in contrast to her canonical first appearance, doesn't do a good job as passing for an ordinary little girl instead of a sentient AI, and thus uses words like "dullard" or "geopolitical" in everyday conversation.
    Kirito: Yui? Where did you learn a word like that?
    Yui: Um... you know... books?
    Asuna: Like what, the dictionary?
    Yui: Yes! (beat) Is that weird?

    Films — Live-Action 
  • In The Man with Two Brains, when Steve Martin, playing a brain surgeon, hits a woman with his car he turns to the little girl standing nearby and tells her to phone his hospital, giving her explicit medical instructions. She repeats everything back word for word and the dialogue continues as follows:
    Girl: Sounds like a subdural hematoma to me.
    Dr. Hfuhruhurr: Oh, it does, does it? Well, it's not your job to diagnose.
    Girl: But I thought...
    Dr. Hfuhruhurr: You thought, you thought. Just go. Three years of nursery school and you think you know it all. Well, you're still wet behind the ears. It's not a subdural hematoma. It's epidural. Ha.
  • This was featured heavily in The Wizard, where all the kids talk like drug dealers and the adults talk like, well, kids.
  • The little girl at the end of Spider-Man 3 haggled like a professional adult and managed to con a fully grown man.
  • Henry talked like this in The Good Son.
  • North and Winchell from North. But then again, the entire point of North is that the bulk of the movie is a hallucination being experienced by a bigoted so-called child prodigy with an overinflated sense of his own importance, so maybe that's not so surprising.
  • In Annie Hall Alvy Singer remembers his child self getting in trouble in first grade for forcing kisses on one of his classmates. When he defends himself as just exhibiting natural curiosity, the little girl says, "For God's sake, Alvy, even Freud spoke of a latency period."

  • Tori Amos's supposedly autobiographical book Piece by Piece has extensive scenes where a single-digit-aged Tori delivers paragraphs of neopagan philosophy to her parents and authority figures that there is no way the young Tori would even have known about, let alone been able to express.
  • Pre-Teen Genius Artemis Fowl uses this extensively. The Eternity Code sees him scare the wits out of an ordinary waitress with his adult (and ultra-sophisticated) behavior, and in The Time Paradox it gets put into perspective when we realize that the "present" Artemis is actually a lot better at acting his age than he was when he was 10. It is tempting to blame Parental Abandonment for this, but The Time Paradox also revealed that he was acting — and speaking — like that even before his father went missing. Though he still thinks like a kid in some ways; in the first book, Holly says something sarcastic about lollipops as she's making her escape, and Artemis' first two thoughts are, in order, that he doesn't like lollipops, and that using the word "lollipop" is beneath the dignity of his intellect. Which, of course, leads one to the question of how he plans to patronize children himself when he grows up.
  • One problem people have with the writing in Ascendance of a Bookworm is that the main characters are mostly very young children, but speak like adults. Characters like Lutz are considered unusually mature, but maturity doesn't equal education and experience.
  • Averted in Ender's Game. Although the children are all child prodigies who are perfectly capable of speaking like this should they choose, among themselves they speak in a multilingual pidgin slang made up of some of the least professorial vocabulary available.
  • Kendra and Seth from the Fablehaven books often use large vocabularies and explain concepts that a thirteen and fifteen-year-old wouldn't be able to fathom. Of course, seeing all of the other words thrown into the narration of the story, the author may just be trying to get kids to learn how to use a dictionary.
  • Played with in Judy Blume's Fudge series - after spending the entire book misusing or mispronouncing words and expressions he picks up from his brother and parents, he finally figures out how to use them correctly just in time to say them to a visiting author/artist at his school, making him seem very precocious.
  • Taken to ridiculous extremes in William D. Hayes' Project: Genius. Basically, the main character discovers while doing homework that reading the dictionary to his infant brother puts the kid to sleep (especially the "S" section). Later on, he decides to convince a local TV station to broadcast a new show using his brother as the "typical baby" for a school project. Shortly before airtime, he points at his brother and tells him to say "Da" and the then eleven-month-old kid says "Pusillanimous."
  • Roys Bedoys: Downplayed. All of the kids (though Roys is the least likely to do it) occasionally use big words, most often Maker (who, in fact, once expressed a desire to “learn all the big words”), but none of them make a habit out of it.
  • George Eliot, in Silly Novels by Lady Novelists, cites the frequent appearance of this as an example of how these novelists can't represent life.
  • Played for laughs in A Spy in the Neighborhood with smart preteen Paul, who goes into too much detail about mundane things in an almost stereotypically Asperger's-like fashion.
  • The protagonists of Twig are a group of eleven- and twelve-year-olds, but they speak using advanced terminology, mimicking the environment and time they were raised in (an Alternate History early twentieth century, in a lab environment). However, they'll often insert more childlike phrases into their dialogue with one another.
  • The Wee Free Men: The Achings only own so many books, and one of them is a dictionary. Also humorously subverted in that Tiffany doesn't know how to pronounce some of the longer or more unusual words. Which is typical of children who learn words from reading books instead of from hearing them. Lampshaded:
    "Zoology, eh? That's a big word, isn't it."
    "No, actually it isn't," said Tiffany. "Patronizing is a big word. Zoology is really quite short."

    Live-Action TV 
  • Inverted, ironically, in Star Trek: The Next Generation with Wesley Crusher; though he's supposed to be a little professor, he sometimes talks like someone half his age. The first season episode "The Naked Now" has him saying "It was an adult who did it!", for example.
  • Dawson's Creek was forged out of this in the fires of Mt. Doom. This was actually lampshaded in a commercial for reruns on TBS. It went something like, "They act like kids, but they don't talk like kids. Coming up next...Dawson's Creek!"
  • Both Frasier and Niles Crane on Frasier, in flashbacks to when they were kids. Also evident in excerpts of their childhood writing, like journals, essays, etc.
  • Henry Dillon from Shake it Up. He's a 10-turned-11-year-old super genius.
  • On Bones, Brennan is teaching her young daughter to speak precisely, including using 5-dollar words.
  • And then there's Young Sheldon, which has the nine-year-old Doctor Sheldon Cooper in it.

     Music Videos 
  • The three singers in Preschool Popstars are only preschoolers. Doesn't stop the blonde one from using the word "fulcrum" in "See Saw" though.

    Video Games 
  • Ace Attorney:
    • Pearl is surprisingly deductive, logical, and aware of the consequences of many things legal and moral, often seen giving advice and added perspective to Phoenix Wright when in a serious moment. Sure, she is the coddled daughter of a Chessmaster, and a spiritual prodigy, but the girl is only nine. Then again, her favorite TV show is Kid's Masterpiece Theatre. In Japanese, she also has an impressive grasp of the complicated system of honorific/humble language. The last case in the original trilogy, however, has as a plot point that while she talks above her grade level, she's not too hot at reading yet. In the Japanese version, she can't fully understand kanji; in the English version, she misreads the phrase gravely roast as roast's gravy.
    • Cody Hackins from the first game is a second grade fan of the Steel Samurai kids show who happened to witness the crime. When Phoenix tries to coax some information out of him by giving him his own trading card, the following exchange occurs:
      Cody: But that's my card! By offering me something I already own, you're in effect eschewing the very basis of our consumer society, namely the principle of fair trade! Man, for a grown-up, you sure are dumb!
      Phoenix: (W-what do they teach these kids in school these days!? Quantum physics!?)
  • Played with in Golden Sun: The Lost Age by Eoleo, who thinks like this when you use your Mind Read spell on him... because he's not old enough to speak yet. However, it also gets lampshaded; one of his playmates complains about his "grown-up attitude". This is given a Call-Back in Golden Sun: Dark Dawn when it's used to hand-wave a grown-up Eoleo's ability to remember events from The Lost Age.
  • The children in Kindergarten and its sequel often use words and phrases you wouldn't expect kindergarteners to know, such as "neanderthal", "octogenarian", and "probable cause". Of course, considering the children's other characteristics, this isn't that surprising.
  • Many important characters in The Legend of Zelda: The Wind Waker are around Link's age, which is somewhere around 10-12. Yet, their dialogue barely differs from that of the adult characters. Especially Medli and Tetra, who are Wise Beyond Their Years. Played with in Ocarina of Time with Saria, who speaks very sophisticated from time to time as well. She looks like a child but is probably much Older Than They Look.
  • Simba, Uhura's infant son in Quest for Glory II, will do this the first time you talk to him. Attempting to talk to him again will have the hero decide not to since he's such a show-off.

    Web Animation 

    Web Comics 
  • In Penny Arcade, Tycho's niece, Anna or "Annarchy," not only speaks with almost ludicrous Sesquipedalian Loquaciousness, apparently taking after her uncle in that regard, but is advanced enough as to be the standby Professor type in the computer game. There is one strip where she speaks somewhat normally, and is immediately chided for it by her uncle.
    • Also, she beat the original Famicom versions of Final Fantasy 1- 3. In Japanese.
  • Several Homestuck characters speak like this. Rose is probably the worst offender, being a thirteen-year-old human girl who talks like H. P. Lovecraft. Karkat and Kanaya talk in a garbled (and in Karkat's case, sweary) version of this kind of speech.
  • Something*Positive: Just about every child talks like a snarky, cynical adult. Including the other snarky, cynical adults that make up the main cast.
  • Lampshade Hanging in Kevin & Kell, when Coney is worrying her group of friends is developing psychologically and she's not:
    Coney: Lin is maturing rapidly ... Tyler has a keen ability to read others ... Harcourt has a transcendent inner awareness about himself ... What's my attribute?
    Wendell: Vocabulary?
  • Saturday Morning Breakfast Cereal constantly has young children discussing advanced philosophical and mathematical concepts, using the correct jargon.

    Web Original 
  • Whateley Universe: Whateley Academy is supposed to be a high school for mutants, with most of its students indeed belonging to the right age group because mutations generally manifest during puberty. You wouldn't believe it from listening in to most of their conversations, though. (In some cases it's justified — some of these kids were already highly educated before they arrived and/or have superhuman mental faculties —, but it's too universal a phenomenon to be explained by that alone.)

    Western Animation 
  • Penny from Inspector Gadget uses semi-big words like "infiltrate" and such, but that's not too bad. What does stick out, however, is something she says in an episode where MAD is trying to turn metal into gold: "If MAD can turn metal into gold, they'll undermine the world economy!" Wow! For someone who's not even in middle school, she's able to understand a concept that most don't learn — or even understand — until high school! Then again, her uncle is a cyborg and she runs around with a laptop before laptops even existed, and no explanation of why is ever given. Penny might just be really, really smart.
  • Hey Arnold! has a kid who said that he wants a role model "that I can look up to emulate." Seeking a role model, and using a word like "emulate"? Not nearly as bad as Arnold telling a marketing man that he "saturated the market" with too much of his product. How old are these kids? Fourth grade.
  • Edd in Ed, Edd n Eddy is a preteen boy who often speaks in long-winded vocabulary, which even Ed of all people comments on.
    Eddy: (to Edd) What's your problem?
    Ed: It's his hat, Eddy. He always wears it, and he talks forever about stuff!
  • The Simpsons: Bart Simpson switches in and out of this trope Depending on the Writer. Lisa, however, is permanently bound to it.
  • This is pretty much the whole gag behind Home Movies.
  • Animaniacs: All three of the Warners have pulled it at some point, if only for a gag.
  • The kids on South Park are ridiculously sophisticated for their age, especially Stan, Kyle, and Cartman. Of course, they pretty much have to be, given that all the adults in town are complete idiots.
  • The ten-year-old Green Lantern from Batman Beyond speaks like this. He is a ten-year-old Green Lantern — and is also the Dalai Lama.
  • Speaking of ten-year-old Green Lanterns, averted in the Justice League Unlimited episode "Kid Stuff", where John Stewart, Superman, Batman, and Wonder Woman are turned into kids to save the day after adults are banished from the Earth. Although this would have been a Justified Trope had they done it, it was much more entertaining to see the superheroes acting like kids, rather than just cuter versions of themselves. Except for Batman who adheres to this trope religiously, which gets a Lampshade Hanging. A rather poignant one, at that.
  • A kid dressed as Batman does this in the Justice League Action episode "Trick or Threat," which is a tip-off he's actually the real Batman, de-aged and memory-wiped by Klarion.
    "It is gratifying seeing adults concerned with preteen oral hygiene."
  • Try watching any cartoon that has been dubbed into Latin American Spanish and pay attention to the dialogue. When a little kid starts talking fancy, with neutral accent and using baroque words, the rest of the world assumes he/she saw way too much TV. And there starts the mocking.
  • Most of the cast of Recess speak like this, but Gretchen is the most obvious example.
  • The Adventures of Jimmy Neutron, Boy Genius. Admittedly Jimmy Neutron tones it down a lot of the time, but sometimes he just can't help it.
  • Dexter from Dexter's Laboratory is a young mad scientist who uses big words a lot in his talking.
  • This is Lincoln's normal way of speaking in Dogstar. He frequently has to dumb it down so the rest of the crew of the Valiant can understand him.
  • The Brain on Arthur is wise beyond his years, so he often uses polysyllabic synonyms for ordinary words, like "minuscule" or "rigorous". He sometimes gets confused by shorter, simpler terms like "goon", though.
  • Apricot does this in Strawberry Shortcake in Big Apple City; justified, since she's a "baby" character like Apple Dumplin', and is just learning to talk. Orange Blossom even explains that Apricot only knows a few words, but they're all big.

    Real Life 
  • The Little Professor speech is considered a sign of Asperger Syndrome (by some). Even Dr. Hans Asperger, who identified the condition, would playfully refer to his patients who had it as "the little professors".
  • Early readers often have this and may run the risk of being mistaken for autistic.
  • Seems to happen a lot with child actors:
  • Harry Truman talked like this as a kid.
  • "Woke Toddler Tweets" are a social media phenomenon where an adult, attempting to create a From the Mouths of Babes effect, quotes their young child as having a right-on opinion about some political topic. Due to most writers being adults, however, these tend to be written in an adult style, making them seem unconvincing. ("Watching the debates and my four-year-old turned to me and said, 'why is democracy dying?'") After a few high-profile Twitter pundits got caught out making up dialogue for their children (or the fact that they even have children in the first place) in 2016, it became common to see parodies exaggerating the implausibility. (e.g. "Watching the debates and my 7-day-old embryo said 'in accordance with Marxist dialectic, capitalism will sow the seeds of its own destruction.'")
