補う
おぎなう · oginau · JLPT N2 · verb-godan
to compensate for
🧵🩹 補 = 衣 (clothing) + 甫: patching a garment, filling what is missing
補 began as mending torn clothes. The same kanji appears in 補足 (supplement) and 補助 (aid). For the sound, oginau works like oh, gimme now: you ask for more to make up a shortfall.
