When “悩” fills a head
Why it is in the set
It comes out on top more often than any other character, which was not planned but is not surprising. It carries a middling weight in the draw and it fits almost every combination of answers to the five questions, so it wins a lot of close contests. The site's own statistics page shows it near the top most weeks.
What a head full of it looks like
The decision you have made and unmade three times. The message you have drafted twice. Lying down and immediately thinking of it. A head led by 悩 is not distressed; it is looping.
Words that use it
悩む (nayamu, to be troubled by), 悩み (nayami, a worry or a problem), 苦悩 (kunou, anguish), 悩ましい (nayamashii, troubling, and also alluring — the two senses sit oddly together and Japanese keeps both).
Kanji it turns up with
迷 (indecision) is its closest relative and they often finish first and second, which the generator treats as a single state rather than two. 悩 with 締 (deadlines) behind it is work; with 恋 behind it, it is not.
Where “悩” comes from
The heart radical 忄 on the left, and on the right a form related to 脳, the brain. A heart and a head, in one character.
That is a good description of what the word means. 悩む is not fear and not sadness; it is the state of a problem going round without resolving.
悩み (nayami) as a noun is what you would call, in English, a thing you are dealing with. It is the ordinary word for it, not a clinical one.
A line you might get for “悩”
