Etymologies

Middle English, from Latin hūmidus, from hūmēre, to be moist.
(American Heritage® Dictionary of the English Language, Fourth Edition)
From French humide, from Latin humidus, correctly umidus ("moist"), from humere, correctly umere ("to be moist"), akin to ūvēns ("moist"), ūvidus, ūdus ("moist"); all from Proto-Indo-European *wegʷ-, *wogʷ- (“wet”). Cognate with Old Norse vǫkr ("moist, damp, wet"), Scots wak ("moist, damp, wetness, moisture"), English weaky ("moist, wet"). More at weaky. (Wiktionary)
