Homo as the genus of the human race, within the order Primates, was formally instituted in Modern Latin 1758 by Linnaeus (originally also including chimpanzees). Used since in various Latin or pseudo-Latin combinations intended to emphasize some aspect of humanity, as in Henri Bergson's Homo faber "man the tool-maker" (in "L'Evolution Créatrice", 1907).
Latin word once used in various phrases in English, often in legal language, where it means "the condition of something, the matter in hand or point at issue;" literally "thing" (see re). For example res ipsa loquitur "the thing speaks for itself;" res judicata "a point decided by competent authority."
