Differences between commerce and trade

In this modern day and age there appears to be no difference between the Words. The Word Commerce derives from the Latin Commercium which means to trade. In the 14th Century the Word Trade developed from a Dutch Word meaning a Track or Course possibly referring to a Trading Ship involved in commerce. Also meaning 'to occupy oneself in something'

.

In the early 20th Century the Word trade adopts an additional meaning other than being connected with commerce. 'Trade' in now refers to an exchange of motor vehicles. In sport, to 'Trade one player for another'. To 'Trade' off is to sacrifice one benefit for another.
