What does finalise mean?
Finalise means to complete or settle something by giving it its final form, so that it is ready to take effect and no further changes are anticipated. It is most commonly applied to plans, agreements, contracts, deals, schedules, and decisions — things that pass through stages of drafting and discussion before being concluded. The word carries a strong sense of conclusiveness: to say that terms have been finalised signals that negotiation is over and commitment has been reached. In everyday and professional English alike, it appears frequently in phrases such as 'finalise a deal' or 'finalise the details'. The spelling with '-ise' follows British convention, while American English typically writes 'finalize'; the two are otherwise identical. Derived from the Latin root finis, meaning 'end' or 'boundary', the word neatly embodies its own meaning: it marks the end of a process. Its usefulness lies precisely in this ability to signal closure clearly and unambiguously.

Whether you write finalise or finalize says more about where you learned English than what you mean — they're the exact same word.

Etymology of finalise
Finalise derives from 'final', which traces back through French to the Latin root finis, meaning 'end', 'boundary', or 'limit'. The verb form arose from combining 'final' with the '-ise' suffix used to form verbs from nouns or adjectives, following a pattern common in verbs like 'legalise' and 'modernise'. The '-ise' spelling is characteristic of British usage, whereas American English favours the Greek-derived '-ize' ending, yielding 'finalize'. Cognates sharing the same Latin root include 'finale', 'finite', and 'infinite'.
