estómago
/esˈtomaɡo/ · B1 · noun · m
stomach
🍽️ estómago = e + stomach-o: same Greek root, stómakhos, from stóma (mouth)
Spanish adds an e- before st- at the start of words (estación, estudiante) and ends in -o. Strip those and you have stomach. The stress falls on TO, marked by the accent: es-TÓ-ma-go.
