The phrasal verb "wear off" is predominantly used in informal speech and writing, often appearing in casual conversations and everyday contexts. It typically means that the effects of something, such as a feeling, a drug, or an emotion, diminish or gradually fade away over time. Commonly used in discussions about medications, such as when a painkiller or anaesthetic loses its effect, 'wear off' can also describe the lessening impact of emotions or states, such as excitement or nervousness, over a period. While used less frequently in formal contexts, it may appear in scientific or medical texts where less formal language is permitted, or in efforts to simplify ideas for the general public.
