The word 'chigger' originates from the American English dialect, derived from the word 'chigoe' (from Spanish 'chigüire', meaning a type of flea or mite). It refers specifically to a small, biting mite that infests the skin.
Think of the word 'chigoe' which refers to a small biting insect — that's why 'chigger' means a tiny mite that bites.
