Sense: adjective/1
Multi-word describes any grammatical unit formed from two or more separate words, including compounds, phrasal verbs, and fixed expressions. Compound (adj.) refers to words made of two roots written as one unit (e.g. 'toothbrush') or hyphenated ('well-known'), making it narrower because it excludes phrasal verbs like 'give up'. Phrasal (adj.) applies specifically to verb–particle combinations ('turn off', 'look after') and is a subset of multi-word units. Multiword (without hyphen) is a less common variant spelling of multi-word with the same meaning. For example, a teacher might say 'multi-word verb' to include both phrasal verbs and prepositional verbs, while 'compound verb' refers only to verbs formed from two roots (e.g. 'to babysit').

Etymology
Formed by combining the prefix 'multi-' (from Latin multus, meaning 'many') with the noun 'word' (from Old English word). The hyphenated adjective pattern follows similar formations such as 'multi-syllable' and 'multi-purpose'. First recorded in linguistic writing in the mid-20th century as English grammarians began classifying verb structures like phrasal verbs as distinct multi-word units.
