caught, captured, understood, got
Al principio, ni siquiera sabía por qué nos habían pillado.
At first, I didn't even know why we had been caught.

Lo han buscado durante seis años, ¡y no lo han pillado aún!
They've been looking for him for six years, and they still haven't caught him!
— M: El maldito (1931)
