abandonner

to give up; to abandon, forsake; to give oneself (to someone)

“Le drap de sa robe s'accrochait au velours de l'habit. Elle renversa son cou blanc, qui se gonflait d'un soupir; et, défaillante, tout en pleurs, avec un long frémissement et se cachant la figure, elle s'abandonna.” — The cloth of her habit caught against the velvet of his coat. She threw back her white neck, swelling with a sigh, and faltering, in tears, with a long shudder and hiding her face, she gave herself up to him.

From Middle French, from Old French abandoner, from a ban doner (“give up to banishment”), from Frankish *bann, from Proto-Germanic *bannaną.
