|Kanji in this term|
/tani/ → /dani/
The kanji spelling is unrelated to the reading, and appears to be a case of semantic ateji or jukujikun. The characters literally mean 壁 (“wall”) + 蝨 (“louse”), possibly as an indication that ticks and mites may be found on walls.
- a tick, a mite: any of various small parasitic arachnids of subclass Acari
- (derogatory, figuratively) a parasite, a layabout, a moocher: someone who lives off of other people
