Drool

In manga and anime, sometimes characters are drawn drooling. This can happen for various reasons:

• They're sleeping, dozing off, or bored.
• They're stupid.
• They're hungry for food, or lusting for something, someone.

In Japanese

The word for "drool" in Japanese is yodare よだれ, also spelled yodare ヨダレ and yodare 涎. This isn't a jouyou kanji 常用漢字, so the word is typically spelled without kanji.

To say "to drool" in Japanese, the noun for "drool" is combined with the ergative verb pair tareru 垂れる, tarasu 垂らす, meaning "to drip."

• yodare ga tareru
  よだれが垂れる
  Drool drips.
• yodare wo tarasu
  よだれを垂らす
  To drip drool. To drool.

• da-eki

Rendering

In some cases, drool is rendered in manga and anime simplified, by merging the shape of the drool with the shape of the mouth, so it looks like the lower lip is dripping. In this case, the drool becomes the same color of lower part of the mouth. For example:

Character: Izumi Konata 泉こなた
Anime: Lucky☆Star, らき☆すた (Episode 4)

In extreme cases, the "drool" will drips lower than the character's jaw and it will make no sense physically speaking.
