Sense: noun/2
All three words describe something newly created, but they differ in scope and register. 'Neologism' is the formal, technical term used in linguistics and academic writing — it refers specifically to a brand-new word or expression that has entered a language, such as 'cybersecurity' or 'vlog'. 'Coinage' (the target word) overlaps closely with 'neologism' but sounds less academic; it can also refer to the process of inventing, not just the result. 'Invention' is much broader — it applies to any newly created thing, from a machine to a story to a word. Use 'invention' when the focus is on creativity itself rather than language. 'New word' is the plainest, most everyday alternative, best suited for casual conversation. For example: 'Scientists track each new coinage in the dictionary' (natural), 'Linguists study the lifecycle of a neologism' (formal), and 'She has an invention for every problem' (broad).

Etymology
The word 'coinage' comes from the Latin 'cuneus' meaning 'wedge'. This became 'coigne' in Old French — a wedge-shaped metal stamp used to press designs onto blank pieces of metal to make coins. English added the suffix '-age' to 'coin' to form 'coinage', which first meant the process of stamping metal into money, and later expanded to mean the coins themselves. The linguistic sense (creating new words) appeared in the 1800s, drawing on the metaphor of 'coining' phrases as if stamping them into existence.
