Seaman comes from Old English 'sǣmann', a compound of 'sǣ' ('sea') + 'mann' ('man, person'). The historical chain includes Old English sǣ and Old English mann. The quoted older senses, "sǣmann", "sǣ", "sea", "mann", and "man, person", supply the semantic anchors for seaman. The formation is best read as compound and borrowed: the word seaman carries its older form-history into a compact English lexical shape. In present English it is used as a noun, "a sailor or person who works aboard a ship". English derivatives include seamanship and seamanlike; related English forms include seafarer and seafaring. The result is a noun whose etymology preserves both the older form and the later English specialization.
