The antonyms for the word "finalization" are the terms like provisional, preliminary, unfinished, incomplete, and tentative. These words are used in cases where something is not yet final or definitive, but still subject to change or revision. The opposite of finalization means that the task, goal, or objective in question is still in the process of being achieved, and there is no clear or definitive outcome. In some cases, these antonyms may represent a state of uncertainty or ambiguity, suggesting that further work needs to be done before a final decision or conclusion can be reached. However, in other situations, they may simply indicate that a definitive result is not necessary, and that some level of flexibility or adaptability is desirable.
