assumer

To take on or accept — a responsibility, a role, a consequence, or, very commonly in casual speech, a fact about oneself (assumer qui on est, to own who you are). This reflexive-identity sense ('j'assume') is everywhere in contemporary French media and conversation.

• Elle assume ses choix, même les plus critiqués. — She owns her choices, even the most criticized ones.
• Il faut assumer les conséquences de ses actes. — You have to accept the consequences of your actions.
• Le nouveau ministre assume ses fonctions dès lundi. — The new minister takes up his duties starting Monday.

Don't translate 'to assume' in the English sense of 'to suppose' with assumer — that's a false friend; French uses supposer or présumer for guessing something, while assumer means to take on or own something.

Often confused with supposer.
