encarcelar
/enkaɾθeˈlaɾ/ · B2 · verb
to imprison, incarcerate
⛓️🔒 en + cárcel (jail) + ar = put into a jail; cárcel sounds like car-sell
Break it down: en- (in) + cárcel (jail, prison) + -ar (verb ending). Literally to in-jail someone. Cárcel comes from Latin carcer, the same root as incarcerate, so the English cognate is a direct match.
