Trades are fundamentally defined as the exchanging of goods and services for something of equal value. However, there are various synonyms for trades that make the concept richer and more meaningful. 'Barter,' for instance, refers to trading goods or services directly without the involvement of money, while 'commerce' suggests the exchange of goods on a larger scale. 'Merchandising' refers to selling goods, whereas 'transaction' refers to any mutual agreement between two parties that results in an exchange. 'Dealings' is another synonym for trades that often carries a connotation of secrecy or deception. The word 'negotiation' also lends itself to the world of trades, emphasizing the importance of collaboration, communication and compromise.
