The word "wears thin" is a phrase rather than a single word. It refers to something becoming less effective, convincing, or enjoyable over time. The etymology of this phrase can be explained by breaking it down into its constituents:
1. "Wears": It comes from the Old English word "werian", meaning "to carry, bear, or have on one's body". It later evolved to also mean "to deteriorate, or become weaker through use or friction". Over time, "wears" came to be associated with the gradual decline of something.
2. "Thin": This word traces back to the Old English word "thynne", meaning "narrow" or "slender". It was sometimes used metaphorically to describe something weak, insubstantial, or lacking substance. "Thin" in the phrase "wears thin" implies that something gradually loses strength or effectiveness.
