c.1250, from Middle French humain "of or belonging to man", from Latin humanus, probably related to homo (genitive hominis) "man", and to humus "earth", on notion of "earthly beings", as opposed to the gods (confer Heb. adam "man", from adamah "ground"). Cognate with O.Lith. zmuo (acc. zmuni) "man, male person." Displaced its Old English cognate guma (from Proto Germanic *guman-) which survives only in disguise in bridegroom. First record of humankind is from 1645. Humanoid (1918) is a hybrid of Latin humanus and Greek -oeides "like", from eidos "form, shape."
How to use "hu·man"?
Human denotes what pertains to mankind, with no suggestion as to its being good or evil: the human race; human qualities; we speak of human achievements, virtues, or excellences, human follies, vices, or crimes. Humane denotes what may rightly be expected of mankind at its best in the treatment of sentient beings; a humane enterprise or endeavor is one that is intended to prevent or relieve suffering. The humane man will not needlessly inflict pain upon the meanest thing that lives; a merciful man is disposed to withhold or mitigate the suffering even of the guilty. The compassionate man sympathizes with and desires to relieve actual suffering, while one who is humane would forestall and prevent the suffering which he sees to be possible. Compare MERCY; PITIFUL; PITY.
