How to use it
Constituir means 'to constitute', 'to represent', or 'to make up'. It is one of the most formal assertion verbs in Spanish academic and legal writing: 'esto constituye una infracción' (this constitutes a violation), 'el acuerdo constituyó un hito' (the agreement constituted a milestone). It is irregular: conjugated like construir (yo constituyo, él/ella constituye, etc.). Don't confuse with consistir en (to consist of — defining composition) or conformar (to make up/compose — more neutral, less evaluative).
Common mistake
Constituir (to constitute/represent) is one of the 'stately' verbs of formal Spanish — overuse in informal contexts sounds stilted. It conjugates like construir: yo constituyo, no *constituisco. The key test: if you can replace it with 'to represent' or 'to amount to' in formal written English, constituir is likely the correct choice. Don't confuse with conformar (to form/make up — more structural, less evaluative).
