agenciárselas

A common reflexive idiom meaning to manage, fend for oneself, or find a way to get something done through resourcefulness — se las agenció para terminar a tiempo. Interchangeable in most contexts with the equally common arreglárselas; both always carry the fixed las.

• Siempre se las agencia para conseguir lo que quiere. — He always finds a way to get what he wants.
• Nos las agenciamos sin ayuda de nadie. — We managed on our own without anyone's help.
• Tuvo que agenciárselas para pagar el alquiler. — She had to figure out a way to pay the rent.

Dropping the fixed las — the idiom only exists as agenciárselas with that pronoun; *agenciarse alone doesn't carry the same 'get by through resourcefulness' meaning.

Often confused with arreglárselas.
