When “癖” fills a head
Why it is in the set
Because the things a head does without being asked are as much a part of it as the things it chooses, and nothing else in the set covers that. It was also checked carefully against the site's own rule about illness: the radical means sickness, but the word does not, and the generated lines stay well clear.
What a head full of it looks like
The phrase you have said four times in this conversation. Checking a pocket you already checked. Noticing yourself doing it and doing it again twenty seconds later. A head led by 癖 is running routines it did not write.
Words that use it
くせ (kuse, a habit or quirk), 口くせ (kuchiguse, a phrase someone always uses), くせ毛 (kusege, unruly hair), 寝くせ (neguse, bed hair), 悪いくせ (warui kuse, a bad habit).
Kanji it turns up with
悩 (worrying) behind 癖 is somebody aware of it. 笑 (laughing) behind it is somebody who has made peace with it.
Where “癖” comes from
The sickness radical 疒 on the outside — the same one in 病 (illness) and 疲 (fatigue) — with 辟 inside for the sound HEKI.
The radical is telling. A 癖 is not a habit you built; it is one that settled on you, like a complaint.
くせ (kuse) covers a nervous tic, a turn of phrase you overuse, and hair that will not sit flat (くせ毛).
A line you might get for “癖”
“Doing the thing again. Has been told about the thing.”
