Word History

Etymology

Middle English, "height, angular height of a celestial body above the horizon," borrowed from Latin altitūdin-, altitūdō "height, high position, downward extension, depth," from altus "extending upward, tall, high, extending downward, deep" + -i- -i- + -tūdin-, -tūdō -tude; altus going back to dialectal Indo-European *al-to- (whence also Middle Irish alt, allt "height, cliff," Welsh allt "hill, steep slope, cliff"), of uncertain origin

Note: Traditionally equated with Germanic *alđa- "old," and further to a verbal base *al- "nourish" (< Indo-European *h2el- "nourish, feed;" see old entry 1), on the assumption that the verbal adjective *al-to- "fully grown, nourished" leads to both "old" and "high." However, both the Latin and Celtic etyma refer primarily or exclusively to points situated above the ground, not human or animal growth, so such a connection is questionable.
