- Accidental Innuendo: The word "Gorn" was mentioned while trying to make a corn for a party.
- And they didn't even wash the letters between unmaking non-food words and making food words. Ew.
- Accidental Nightmare Fuel: If the WordFriends' words are debuilt, they might look like they're dead. Good thing that didn't happen, as this is a show for preschoolers.
- Ear Worm:
- The theme song.
- "It's time to build a word! Let's build it! Let's build it now!" It doesn't help that it's generally used Once per Episode.
- Friendly Rivalry: With Super Why!. Not only do they teach us about letters or air on the same channel, but they also premiered on the exact same day.
- Also WordGirl and Martha Speaks, which also involved words.
- Les Yay: One episode centers on Sheep writing a love song to Bear (for Valentine's Day, but still). Um...
- The same episode centers on Frog helping Bug write his name on a Valentine. Turns out the Valentine is for Frog, and they hug for a very long time, gazing into one another's eyes.
- Uncanny Valley: Enough said.
- What Do You Mean, It Wasn't Made on Drugs?: The premise, to some.
