The word 'washerwoman' is a transparent compound formed within English. Its first element, 'washer', derives from the Old English verb 'wæscan', which has Proto-Germanic origins related to the concept of water. The agent suffix '-er' (from Old English '-ere') was added to create 'washer', a common term for one who washes. This was then combined with 'woman', a word of Old English origin ('wīfmann'), to specify the gender of the laborer. The term vividly illustrates a historical occupation, literally meaning "a woman who is a washer," and reflects a time when laundry was a significant, often gendered, form of manual labor.
