entrenar
/entɾeˈnaɾ/ · B1 · verb
to train
🚂 en-TREN-ar: tren is Spanish for train, so entrenar = to train
English train (to coach) and train (railway) are the same word, and Spanish keeps the link: tren sits inside entrenar. Both come from French traîner, to pull or drag along. A coach pulls athletes forward the way an engine pulls carriages.
