Etymology
From Medieval Latin nadir, from Arabic نَظِير السَّمْت (naẓīr as-samt), composed of نَظِير (naẓīr, “counterpart, corresponding to”) and السَّمْت (as-samt, “the zenith”).
Unknown. It has been suggested that it is from Arabic نَزِير (nazīr, “rare, trivial”), but if it is Arabic, perhaps more likely would be نَذِير (naḏīr, “auspicious, boding well (?)”). Represents the word 'rare' in Hebrew.
Webster’s 1913
- noun That point of the heavens, or lower hemisphere, directly opposite the zenith; the inferior pole of the horizon; the point of the celestial sphere directly under the place where we stand.
- noun The lowest point; the time of greatest depression.
Etymology [F., Sp., & It. nadir; all fr. Ar. nasiru's samt nadir, prop., the point opposite the zenith (as samt), in which nasir means alike, corresponding to. Cf. Azimuth, Zenith.]
