The word 'worker' is a transparent compound from the Germanic linguistic tradition. Its first element, 'work', originates from the Old English noun weorc, which itself stems from the Proto-Germanic werkan, carrying the fundamental sense of "to do" or "to perform." The agentive suffix '-er' has a complex history, entering Old English as -ere from a Proto-Germanic form that was influenced by the Latin agent-noun ending -ārius. The literal combination, "one who works," has remained remarkably stable in meaning from its Old English formation to modern English. It logically evolved from denoting any person performing an action to specializing in signifying someone engaged in physical or industrial labor, reflecting societal and economic structures.

Structure: work (action of labor) + er (agent suffix) - work: From Old English weorc, meaning "something done, action, deed, labor." Its functional role is the core semantic root denoting productive activity. - er: From Old English -ere, an agent-noun suffix derived from Proto-Germanic -ārijaz, borrowed from Latin -ārius. Its functional role is to form a noun indicating a person who performs the action of the verb.
