2255: Hebrew Contronyms Feb 17, 2021
Hebrew has a causative form for verbs which effectively reverses the meaning of the word, so הוא לומד means 'he learns' and הוא מלמד means 'he teaches', from the same root. It also has a number of contronyms that don't need to change form at all. For instance ללכת usually means 'to go' and לבוא usually means 'to come' but in certain cases that can effectively switch, such as in בא השמש (literally: the sun is coming) referring to a Sunset.
