What is the difference between definite and definitive?
These words are not that different, as both refer to something precisely defined or set forth. Definitive, however, specifically applies to a description or judgment that is a standard or reference point for others, or being the most complete or authoritative. Definitive means 'having the function of deciding or settling' or being 'conclusive'. Here are some examples: She has a definite opinion on most topics. I want a definite answer on what we shall eat for dinner tonight. / The Oxford English Dictionary is the definitive guide to the English language. It was a definitive victory for the political candidate.
