Nadir Has Arabic Roots
Nadir is part of the galaxy of scientific words that have come to us from Arabic, a language that has made important contributions to the English lexicon especially in the fields of mathematics, astronomy, medicine, and chemistry. The source of nadir is naḍhīr, meaning "opposite"—the opposite, that is, of the zenith, the highest point of the celestial sphere which is positioned vertically above the observer. (The word zenith itself is a modification of another Arabic word that means "the way over one's head.") According to our sources, usage of nadir reached an apex in the 1980s. But worry not for the word’s future: it’s still flying high.
