Sense: noun/1
All four words describe giving something and receiving something in return, but they differ in formality, scope, and context. 'Exchange' is the broadest and most neutral term, suitable for both formal contexts (diplomatic exchange, exchange of contracts) and everyday situations (exchange of gifts, phone numbers). 'Swap' is informal and strongly conversational — you swap seats, swap recipes, or swap clothes with a friend. 'Trade' carries a commercial tone and often implies professional or business transactions, though it is also used casually ('I'll trade you my sandwich for your chips'). 'Barter' is the most specific: it refers to exchanging goods or services directly without using money, typically in informal economies or historical contexts. For example, if two friends swap books, that is a swap; if two companies exchange technology patents, that is an exchange; if a farmer gives vegetables to a carpenter in return for a table, that is barter.

Etymology
'Exchange' entered Middle English in the 13th century through Anglo-French 'eschaunge', derived from Old French 'eschangier' — combining 'es-' (meaning 'out, thoroughly') and 'changier' (to change). The French verb traces back to Latin 'cambire' (to exchange, to barter). The word originally referred to the mutual giving and receiving of goods or money, and over centuries its meaning expanded to include conversations, visits, and financial markets.
