益 is a bound form (b.f.) that does not stand alone as an independent word. It appears in compounds with the core meanings of 'benefit', 'advantage' (noun), 'beneficial', 'profitable' (adjective), and 'increasingly', 'even more' (adverb). Common compounds include 利益 (lìyì, benefit), 有益 (yǒuyì, beneficial), and 日益 (rìyì, increasingly). It has a classical Chinese origin and is used in formal and written contexts. Its hexagram sense (䷩) is very rare.
