Showing abilities or qualities at an earlier age than usual, especially in terms of intelligence or talent.

Precocious → It is formed from "prae-" (meaning before) and "coquere" (meaning to cook or ripen). The word describes someone who is developed or matured before the usual time, as if they have 'ripened' early.
Think of someone who is 'ripening' ('coquere') 'before' ('prae-') their peers — that's why precocious means developing early.
