adjective Superlative of good.
Origin: Middle English
Origin: , from Old English betst; see bhad- in Indo-European roots.

This rule is often ignored in practice, but it still has many devoted adherents. In certain fixed expressions, however, best is used idiomatically for comparisons between two: Put your best foot forward. May the best team win! See Usage Notes at have, rather.
