些微 is listed as a noun meaning 'a tiny amount, a very small quantity'. However, in modern usage, it often functions adverbially like 'slightly' — before adjectives or verbs — but strictly speaking, its core noun sense appears in phrases like '加些微的糖' (add a trace amount of sugar). The POS field labels it as a noun, but the gloss is primarily adverbial, which creates a mismatch.
