late Old English godsibb, ‘godfather, godmother, baptismal sponsor’, literally ‘a person related to one in God’, from god ‘God’ + sibb ‘a relative’ (see sib). In Middle English the sense was ‘a close friend, a person with whom one gossips’, hence ‘a person who gossips’, later (early 19th century) ‘idle talk’ (from the verb, which dates from the early 17th century).
