atangayarse

A rare regionalism from El Salvador and Honduras (marked "poco usado" even there) meaning to become exhausted or worn out, left without strength — describing a person or animal too tired to go on. It's not part of standard Spanish and would be unfamiliar to the vast majority of Spanish speakers, including most Central Americans outside those two countries.

• El caballo se atangayó después de la larga subida. — The horse became worn out after the long climb.
• Terminó tan atangayado que no pudo ni cenar. — He ended up so exhausted he couldn't even eat dinner.
• Con este calor uno se atangaya rápido trabajando en el campo. — In this heat you get worn out fast working in the field.

Expecting atangayarse to be recognized outside El Salvador and Honduras — agotarse or cansarse are the words that would be understood across the Spanish-speaking world.

Often confused with agotarse.
