The word "full-time" combines "full," from Old English full (meaning "complete" or "entire"), and "time," from Old English tīma (meaning "period" or "duration"). It emerged in the early 20th century to describe employment or activities occupying the standard working hours, contrasting with "part-time." The morphemes retain their original meanings, emphasizing completeness ("full") within a specified period ("time").
