descender
/desθenˈdeɾ/ · B1 · verb
to descend
🪜 descender = descend + -er, the Spanish verb ending: to go down
From Latin descendere: de- (down) + scandere (to climb), so it means to climb down. English descend comes from the same root. It is irregular: the e changes to ie in forms like desciendo (I go down).
