The word 'tradesman' is a transparent compound formed within English. Its first element, 'trade', originates from the Middle Low German 'trade', meaning "track, course", which metaphorically extended to the regular course of business. The '-s-' is a fossilized genitive or plural marker, common in English compounds (e.g., 'kinsman', 'sportsman'), indicating "of or pertaining to trade". The second element, 'man', from Old English, denotes the person performing the associated action. Thus, the literal construction "man of trade(s)" logically evolved to specify a person whose occupation involves buying, selling, or skilled craftwork for commerce, distinguishing them from professionals or laborers.

Its functional role is the core semantic root. - s: A Middle English genitive or plural inflection, here forming a compound.
