businessman

The word 'businessman' is a transparent compound formed within Modern English. Its first element, 'business', originates from the Old English adjective bisig, meaning "busy" or "occupied," combined with the noun-forming suffix -ness to denote "the state of being busy." By the 14th century, this evolved to specifically mean "one's occupation or commercial dealings." The second element, 'man', from the Old English mann, broadly meant "person" but has historically been used in compounds to specify a person engaged in a particular activity. Thus, 'businessman' logically constructs the meaning of "a person (traditionally male) engaged in commercial activity," reflecting a straightforward compounding process where the modern abstract meaning is a direct sum of its parts.

Structure: business (activity) + man (person) business: From Old English bisig (busy, anxious, occupied) + -ness (noun-forming suffix denoting state or quality). The functional role is the core concept of commercial or professional activity. man: From Old English mann (human being, person, adult male). The functional role is to denote a person associated with the preceding concept.
