Synonym discussion
Sense: noun/1
'Chums', 'friends', 'pals', 'mates', and 'buddies' all describe people who enjoy each other's company, but they differ in tone and variety. 'Friends' is the neutral word and works everywhere. 'Chums' feels older, warmer, and a little British, and it often suggests people who have known each other for years, especially from school or early life. 'Pals' is also informal but sounds more current in American English, while 'mates' is the everyday choice in British and Australian speech. 'Buddies' sounds relaxed and modern, especially in North America. If two retired neighbours meet for tea every week, 'old chums' fits well; if two coworkers chat after lunch, 'friends' or 'buddies' usually sounds more natural.
Etymology
Chums is the plural form of the noun chum and also the third-person singular form of the verb. The friendship sense grew out of late seventeenth-century English university slang, where a chum was originally a roommate or close companion. The fishing bait sense and the related verb come from a different nineteenth-century coastal word, probably linked to a term for food scraps. The salmon sense came into English through Chinook Jargon in the Pacific Northwest. Modern English now uses the same spelling for three different historical lines.
