What does complete mean?
Complete is one of English's most versatile everyday words, serving both as an adjective meaning 'having all its parts' or 'finished' — a complete meal, a complete set of tools — and as a verb meaning 'to bring to an end' or 'to make whole', as when you complete a form, a course, or a jigsaw puzzle. Beyond its literal sense, complete works as a powerful intensifier: a complete failure, a complete stranger, a complete surprise — usages that stress absolute degree rather than physical wholeness. The word carries broadly positive connotations of thoroughness and accomplishment, though in intensifying uses it can attach to negative nouns too. Derived forms such as completely, completion, and completeness extend its usefulness across registers. Its Latin ancestry, rooted in the idea of 'filling up', quietly reminds speakers that to complete something is, at heart, to fill it full.
Having all the necessary or appropriate parts; entire; also, finished or ended.
"The collection is now complete after thirty years of searching."
Often used attributively as an intensifier before a noun to indicate totality.
To bring to an end; to make whole or perfect by adding what is lacking.
"She completed the marathon just under four hours."
Common in instructional and administrative contexts, e.g. forms, courses, and transactions.
Every time you say 'complete,' you're literally saying 'filled up' — it comes straight from the Latin for 'to fill full.'

Etymology of complete
Complete entered English from Latin completus, the past participle of complere, meaning 'to fill up' or 'to fill full', formed from com- ('together, thoroughly') plus plenus ('full'). It arrived via Old French in the late Middle English period, around the fourteenth to fifteenth century. The same Latin root gave English a cluster of relatives, including complement, comply, plenty, and replenish, all preserving the core notion of fullness or filling.

How complete is actually used
As an adjective, complete frequently functions as an intensifier before nouns ('a complete waste of time'), where it emphasizes totality rather than literal wholeness. The verb is standard in both formal and everyday contexts, especially in instructions ('complete this section'). British and American usage are essentially identical.
Easily confused with complete
'Complete' means whole or finished, while 'complement' (with an e) refers to something that completes or enhances something else — often confused because both derive from the same Latin root.
