monja
/ˈmonxa/ · B1 · noun · f
nun
⛪ monja = monk + a, the feminine ending; both come from Greek monos, alone
Spanish monja and English monk share one root: Greek monachos, a solitary person, from monos, alone (as in monologue). Swap monk's k for the j sound and add the feminine -a to get monja, a nun.
