Some tropes can be pretty broad. Some can be so broad that even a specific form of them can be tropes by themselves.

Let's say there's a trope for "Juggling". You realize that "Scarf Juggling" and "Knife Juggling" are pretty common as well, to the point where you can think of half a dozen examples for both. Those would be Sub-Tropes, whereas "Juggling" in general is their SuperTrope. In [[http://en.wikipedia.org/wiki/Genus–differentia_definition logic terms]], "Juggling" is the genus and the different kinds of juggling are the differentia; they share the same common theme in their definition, but they each have additional features that distinguish one from another.

What makes a sub-trope can vary. Perhaps the most common way is that several examples of a trope have a distinctive common element not seen in the other examples. That makes the super trope separate from the larger trope. Or, as mentioned above, a trope can have several possible variations built in, and once examples of any of those variations are common enough, they form a sub-trope. These sub-tropes can be listed instead of the super trope, seeing as the sub-trope implies the presence of the super trope.

Heck, some tropes can be sub-tropes of more than one super trope. This can be a shared aspect of them or actually [[JustForFun/XMeetsY combining the two tropes]].

Now the definition of the super and sub tropes are what's important. In most cases, every example of a sup trope will also be an example of its super trope, but there are some exceptions. Fortunately it's good troping etiquette to just list sub trope examples on those pages instead of the super tropes (to avoid page bloat), rather than worrying if every example fits the larger trope.

!!Notable Sub-Tropes

* ChemicalMessiah is a subtrope of TerminallyDependentSociety.
* HeroBall and VillainBall are subtropes of IdiotBall, just applying to actions typical of those characters.
* MarySue has enough variations that it's split into several types.
* OurMonstersAreDifferent shows that fantasy writers often use various and different rules to portray some of the most popular mythical creatures. Each subtrope deals with the most common rules that appear in works involving [[OurDragonsAreDifferent dragons]], [[OurVampiresAreDifferent vampires]] (actually, vampires get [[YourVampiresSuck two]]), [[OurWerewolvesAreDifferent werewolves]], [[OurGhostsAreDifferent ghosts]]...
* ParentalAbandonment refers to the common device of parents who are missing or dead. Some subtropes are MissingMom and DisappearedDad, when only one parent is unavailable.
* WhatMeasureIsANonCute points out the recurring protrayal of cute animals as the good guys and non-cute animals as the bad guys. ReptilesAreAbhorrent is a subtrope of this, as it points out that reptiles are almost always protrayed as evil and vicious.
* DeusExMachina is a subtrope of AssPull, where the pull is used to resolve the conflict.
* ImpossiblyCoolClothes is like an ImpracticallyFancyOutfit, but almost strictly done in drawn media, because that kind of outfit can barely even be worn at all in real life.
* FanHater is a subtrope of {{Hatedom}}, in that they hate both the work and the fans of that work. If they hate just the work, it's the latter trope.
* TooIncompetentToOperateABlanket is a variation of StrawmanProduct, in that the strawman aspect is making a product look far harder to use than it actually is.
* HeroicResolve is a subtrope of both HeroicSpirit and UnstoppableRage.
* PrincessClassic is a form of EverythingsBetterWithPrincesses, but about a specific archetype of them.
* HypnotizeThePrincess is literally the DistressedDamsel being [[{{Brainwashed}} Hypnotized]].
* BigBulkyBomb is StuffBlowingUp when the explosive device is really big (regardless of the actual explosion).
* CanisMajor and MegaNeko are BiggerIsBetter applied to canines and felines, respectively.
* SomethingElseAlsoRises is a form of DoesThisRemindYouOfAnything, where the "anything" is... male... "excitement".
* AliceAllusion is a basically a ShoutOut to ''Literature/AliceInWonderland''
