Tentative → It is formed from "tentare" (meaning to try or attempt) and the suffix "-ive" (meaning having the nature of). The word "tentative" describes something that is in the nature of trying or is not fully decided or definite.
Think of 'trying' ('tentare') something out — that's why tentative means something that is not yet fully decided.
