'gossip-related' originates in Modern English as a compound formed from 'gossip' + 'related'; 'gossip' itself ultimately comes from Old English 'godsibb', where 'god-' meant 'god' and 'sibb' meant 'relation/kinsman', and 'related' comes from Latin 'relatus' via English 'relate'.

'gossip' changed from Old English 'godsibb' (originally 'god-parent, sponsor') into Middle English 'gossip(e)' meaning 'close companion, familiar', then shifted to mean 'person who engages in chatter' and finally 'idle talk' in modern English; 'gossip-related' arose by compounding the noun with the adjective 'related'.

Initially, 'godsibb' referred to a godparent or intimate relation; over time the sense shifted through 'close companion' to 'one who chatters' and then to 'idle talk' or 'rumor'. The compound 'gossip-related' now means 'connected with that idle talk or rumor behavior'.
