What does the name 'Cricket' mean?

Answer 1

The first definition is the insect, coined in the 14th century, after the 12th century Old French criquet, from criquer, meaning "to creak, rattle, crackle", of echoic origin.

The second definition is the game, also from the Old French root word criquet, but probably from the same root as crutch.

In the sense of "fair play", c.1851 "cricket as it should be played".
