善し悪し
よしあし · yoshiashi · JLPT N1 · noun
bad
⚖️ 善 (good) + 悪 (bad) + し (verb suffix): 'good-bad' weighed like a scale, so it means the pros and cons, the merits and demerits
Read it as 'good-and-bad' and you get the sense of weighing both sides. Sounds like 'yoshi-ashi', as in 'yosh, ashi' (good, bad).
善 — sheep 羊 over 言 (speech), simplified to 善
Originally written with 羊 (sheep, auspicious) above two 言 (speech) elements, depicting auspicious or kind words. The form was simplified to one mouth-like base under 羊. The meaning shifted from 'auspicious speech' to the broader senses 'good, virtuous, skilled at.'
