negarvsnegarse
/neh-GAR/
/neh-GAR-seh/
💡 Quick Rule
Negar = Deny a fact. Negarse = Refuse an action.
Think: 'Negar' is for your mouth (denying words). 'Negarse' is for your body (refusing to act).
- The main confusion comes from English, where 'deny' can mean both. For example, 'they were denied entry' is 'les negaron la entrada', not reflexive.

Frequently Asked Questions
Why does 'negarse' need the 'se' part?
The 'se' is a reflexive pronoun. In Spanish, many verbs change their meaning when you add a reflexive pronoun. For this pair, the pronoun turns the meaning from 'to deny a fact' (negar) to 'to refuse an action' (negarse a + infinitive).
Can I say 'negar a hacer algo'?
No, that's incorrect. When you're talking about refusing to do an action, you must use the reflexive form: 'negarse a hacer algo'. For example, 'Me niego a salir' (I refuse to go out).
