asumir
/asuˈmiɾ/ · A2 · verb
to assume, take on
Latin ad + sumere = take to oneself; twin of English assume
From Latin assumere: ad (to) + sumere (take). Same root as English assume, so both senses carry over: taking on a duty or role (asumir la responsabilidad) and supposing something is true. Drop one s and swap the ending to -ir.
