Etymology: Antineoplastic is a modern medical coinage built from Greek parts, and its history runs through a bundle of older words. The first piece, "anti-", comes from Ancient Greek "ἀντί", meaning "against" or "opposite". The second part, "neoplastic", combines "neo-", from Greek "νέος" meaning "new", with "plastic", from the Greek verb "πλάσσω", meaning "to form or mould", which gave Latin "plasticus" and English "plastic". So a neoplasm is literally a "new formation", the medical term for an abnormal growth such as a tumour. The word itself is not ancient. Its parts were combined in the medical vocabulary of the modern era, so no Greek or Roman physician would have recognised it. English took "neoplastic" first as a technical term describing growths, and "antineoplastic" was then formed by attaching "anti-" to it, describing agents that work against tumour growth. The pattern is the same as in other clinical words, such as "antibiotic", where a classical prefix is simply stacked onto a newer coinage.
