When “怒” fills a head
Why it is in the set
Because irritation takes up more room in an ordinary day than any grander feeling does, and a set without it would be dishonest. The trick was making it funny without making it aggressive. What the quips describe is the anger that has outlived its cause: the one you are still carrying about something that stopped mattering weeks ago.
What a head full of it looks like
Rehearsing what you should have said. Being short with someone who had nothing to do with it. Discovering that a small noise has become unbearable. A head led by 怒 is usually a head that is tired and has misfiled the reason.
Words that use it
怒り (ikari, anger), 激怒 (gekido, fury), 怒鳴る (donaru, to shout), 怒りっぽい (okorippoi, quick to anger), 天の怒り (ten no ikari, the wrath of heaven — used about weather, half jokingly).
Kanji it turns up with
忙 (busy) behind 怒 is the most common combination and the most explanatory one. 怒 with 眠 (sleep) behind it gets a quip about four hours of sleep, because that is usually what it is.
Where “怒” comes from
A heart, 心, at the bottom. Above it 奴, which supplies the sound DO.
Japanese has two readings with slightly different weights. 怒る as okoru is everyday: a parent okoru at a child. 怒る as ikaru is heavier and more literary.
The heart radical at the bottom of a character is a reliable signal. 思 (to think), 怱 (to worry), 悲 (sorrow), 感 (to feel) all have it, all in the same position.
A line you might get for “怒”
