The phrasal verb "wear out" is commonly used in informal speech and less so in formal contexts. It generally refers to the condition of something becoming damaged or ineffective due to extensive use, signifying a process of deterioration or exhaustion. For example, one might say, "My old shoes have worn out," indicating that the shoes are no longer in good condition due to repeated use. It can also be applied figuratively to describe a person becoming exhausted or fatigued, as in "He is worn out from all the work." In professional writing or formal discussions, alternatives like "exhaust," "deplete," or "wear down" might be preferred for clarity and formality. This phrasal verb is versatile and used both literally for objects and metaphorically for people, making it prevalent in everyday conversations.
