The word "washer" derives from the verb "wash," which traces back to Old English wæscan (to cleanse with water), from Proto-Germanic waskaną. The suffix "-er" is an agentive suffix in English, indicating a person or thing performing an action. Originally referring to a person who washes (e.g., a laundry worker), the term later expanded to mechanical contexts (e.g., a washing machine or a sealing ring in machinery). The dual meaning reflects the word's functional evolution from human labor to mechanical utility.
