cargar

One of the most common Spanish verbs: to load or carry (cargar el coche, to load the car; cargar una maleta, to carry a suitcase), to charge (cargar el móvil, to charge the phone; cargar una tarjeta, to charge/bill a card), and reflexively, colloquially, to break or ruin something (se cargó el jarrón, he broke the vase) or, more darkly in slang, to kill someone.

• Cargó las maletas en el coche. — He loaded the suitcases into the car.
• Necesito cargar el móvil, se está quedando sin batería. — I need to charge my phone, it's running out of battery.
• Se cargó el jarrón sin querer. — He accidentally broke the vase.

The reflexive cargarse has a very different, informal meaning ('to break/wreck something,' or worse) from the plain cargar ('to load/charge') — context and the reflexive pronoun matter enormously here.

• expression "Cargar las tintas" — A common fixed expression meaning to exaggerate or overstate something for effect, originally from journalism, where a paper would keep running articles on a story to milk its importance.
• expression "Cargar con el muerto" — A widely used idiom meaning to take the blame for something one didn't do, traced by popular etymology to medieval Spanish law, under which a town found with an unclaimed murder victim within its bounds could be collectively fined.
