状 is a bound form (bound morpheme) that never stands alone in modern Chinese; it always appears as part of a compound word. Depending on the compound, it can mean 'state/condition' (状态, 状况), 'shape/form' (形状), or 'account/record/legal document' (告状, 诉状, 奖状). The compound 状语 is a linguistic term meaning 'adverbial modifier'. Because its meaning varies widely by context, you need to learn the full compound rather than treating 状 as an independent word.
