Can you have two best friends? Someone posted this question on Grammarly Answers. Why a question about friendship? The grammar issue has to do with the adjective “best.” Best is a superlative. Let’s discuss what that means.
Suppose you have three rich friends. Bob has five million dollars. Bill has eight million dollars. Bernice has two million dollars. If you were comparing two friends, you would use a comparative adjective: Bill is richer than Bob.
