Origin
From French psychologie, from Renaissance Latin psychologia, from Ancient Greek ψυχή (psukhḗ, “soul”) + -λογία (-logía, “study of”), equivalent to psycho- + -logy. The Latin term is believed by some to have been coined in a lost treatise by Croatian humanist Marko Marulić (1450–1524), but this is disputed by other scholars. It is first attested in the 1570s, at which time it was apparently already current, and may be a Hellenization of the established expression dē animā (“on the soul”) in titles.
