inmortal
/immoɾˈtal/ · B1 · adj
immortal
♾️ in- (not) + mortal: in-mortal is not mortal, same as English im-mortal
From Latin immortalis: in- meaning not, plus mortalis, from mors, meaning death. Spanish keeps the n in front of m (inmortal), but English changes it to im-. The m sound gets held longer, so it comes out as im-mor-TAL, stressed on the last syllable.
