exchange
🔄🤝 inter + cambio = between + change, like a change passed between two sides
From Latin inter (between) + cambiare (to change, swap). Cambio alone means change or currency exchange, as at a casa de cambio. Add inter- and it becomes a swap between parties, as in an intercambio de idiomas, a language exchange.
