損う
そこなう · sokonau · JLPT N1 · verb-godan
to harm
🩹 損 (son) means loss or damage, so 損う = to cause loss, i.e. to harm (cf. 損害 songai, damage)
The kanji 損 (son) carries the sense of loss or damage, as in 損害 (songai, damage). Sokonau turns that sense into a verb meaning to harm or hurt someone or something.
