Antonymns in Arabic

Antonyms in Arabic are a strange phenomenon. There is a whole category of words that mean one thing as well as its opposite. For example, the word, "saleem," means the one who is cured as well as the one who has just been bit by a snake. The word baseer, means one with great sight and insight, but also means blind. Mawla means master and slave and wala means to follow and to lead, The word umma, which is usually translated as nation, means the entity that is followed, or the guide, as well as the entity that follows and is guided.
