Etymology: Psycholinguistics is a modern compound, built in English from two Greek-derived pieces. The first, "psycho-", comes from ancient Greek "psūkhḗ", meaning soul, breath or mind, and the second is "linguistics", which itself combines Latin "lingua" (tongue, language) with the "-ist" and "-ics" endings that English uses for fields of study. Put together, the word names the study of how the mind acquires, produces and understands language. The pieces are older than the compound. "Psūkhḗ" was used in ancient Greek for the breath of life and, later, for the soul, and English took the "psycho-" element from it in modern scientific coinages. "Linguistics" is likewise a relatively recent English formation from Latin roots, with the "-ist" suffix passing through Old French and Middle English before English added its own "-ics" for disciplines. Psycholinguistics is therefore a straightforward combining form rather than a word with a dramatic history. Its meaning is simply its parts: the psychology of language, with the mind as the object of study and language as the tool being examined.
