infierno
/inˈfjeɾno/ · A2 · noun · m
hell
🔥 infierno = inferno with an extra i; both from Latin infernus, the place below
English inferno is the same word, borrowed via Italian. Spanish turned the stressed Latin e into ie, as in tierra and tiempo, so infernus became infierno. Latin infernus means lower or underneath: hell is the place below.
