The word 'anybody' is formed from 'any' (from Old English 'ænig', meaning any or one) and 'body' (from Old English 'bodig', meaning body or person). The term 'anybody' refers to any person or any individual without specification.
Think of 'any' meaning one of many and 'body' referring to a person — so 'anybody' means any one person.
