'Come across' is predominantly used in informal speech and writing, where it conveys the sense of encountering something or someone by chance. It's a versatile phrasal verb often employed in personal anecdotes or narratives, such as "I came across an interesting article today" or "I randomly came across my old friend at the market." It can also be used in a more figurative sense to describe how something appears or is perceived, as in "He comes across as very confident during interviews." It is a commonly used expression that adds a conversational tone to communication, making it less prevalent in formal contexts, where terms like 'encounter' or 'meet' might be preferred. Nevertheless, its ubiquity in spoken English underlines its utility in conveying spontaneity and unexpectedness in discovering or perceiving people, objects, or ideas.
