How it's used
Unlike the everyday word 蠢, which is used constantly in casual speech, 愚 is a morpheme primarily found in formal, literary, or compound words. It carries a more serious or intellectual weight compared to the blunt, informal nature of 蠢. You will rarely hear it used as a standalone adjective in spoken Cantonese.
Examples
He is usually quite silly and gets tricked all the time.

Common mistake
Learners often try to use 愚 as a direct replacement for 蠢 in casual conversation, but this sounds unnatural and overly formal. Stick to 蠢 or 笨 for daily life.
