kayaker

The word 'kayaker' is a modern English formation that combines a borrowed noun with a native agent suffix. Its core, 'kayak', entered English in the mid-18th century from Danish 'kajak', which itself was borrowed from Greenlandic Inuit 'qajaq', referring to a sealskin-covered, one-person canoe used for hunting. The English suffix '-er', of Germanic origin, is productively attached to nouns to indicate a person who uses or is associated with that object. Thus, the literal construction "kayak-user" directly and logically yields the modern meaning of a person who paddles or operates this specific type of lightweight canoe.

Structure: kayak (a type of canoe) + er (agent suffix) kayak (from Inuit/Eskimo-Aleut languages, via Danish, meaning "man's boat" or "hunting boat"); er (from Old English -ere, an agent-noun suffix denoting a person associated with an action or thing).
