Origin & History of “gravity”

Gravity comes from Latin gravitās, a derivative of the adjective gravis ‘heavy, important’. this in turn goes back to a prehistoric Indo-European *gru-, which also produced Greek bárus ‘heavy’ (source of English baritone (19th c.) and barium (19th c.)), Sanskrit gurús ‘heavy, dignified’ (whence English guru (17th c.)), Latin brūtus ‘heavy’, hence ‘cumbersome, stupid’ (from which English gets brute), Gothic kaurus ‘heavy’, and Latvian grūts ‘heavy, pregnant’. English descendants of gravis, apart from gravity, include grave ‘serious’, gravid ‘pregnant’ (16th c.), gravitate (17th c.), grief, and grudge.
