Finalise vs. Finalize: What's the Difference?

Edited by Harlon Moss || By Janet White || Updated on October 3, 2023
"Finalise" and "finalize" both mean to complete or conclude something, with "finalise" being British English and "finalize" being American English.

Key Differences

"Finalise" represents a word that is predominantly observed in British English, primarily referring to the act of completing, concluding, or making a decision or agreement final and unalterable. On the other hand, "finalize" is the counterpart used in American English, signifying essentially the same: reaching a conclusive point where something is determined or rendered complete. The variation in spelling, with “-ise” versus “-ize”, is a typical difference found in British and American English respectively.
In a context where an individual might say, "We will finalise the details tomorrow" in the UK, an American counterpart might express the same intent by saying, "We will finalize the details tomorrow". The meaning remains intact across these two versions, even as the spelling changes to align with regional language norms. Both words imply reaching a resolution or firm conclusion regarding the matter being discussed.
In documents or communication where adherence to British English is expected or necessary, "finalise" would be the suitable choice to convey completion or conclusiveness. Conversely, in settings where American English is the standard or where international audiences (who often engage with American English) are the target, "finalize" would be appropriately employed.
The importance of choosing "finalise" or "finalize" appropriately extends to maintaining consistency in language use across a document or communication. For instance, adhering to British English might also involve selecting "organise" over "organize", maintaining a coherent linguistic approach. When considering these two words in professional, academic, or formal writing, paying attention to the intended or expected language variant is crucial.
In summary, while "finalise" and "finalize" provide identical semantic value, serving to express the act of completing or making something definite, the selection between these two is generally guided by the linguistic norms of either British or American English. Knowing your audience, the context, and the applicable language standards will guide the appropriate use of either term.
