The phrasal verb "pour in" is commonly used in informal contexts and can also appear in more formal speech or writing depending on the context. It generally describes the action of something arriving or accumulating in large quantities or numbers, often unexpectedly or continuously. For example, it may be said that entries for a contest or requests for information 'poured in' after the announcement, indicating a significant influx. It's flexible in usage, often linked with things like rain, money, or people, especially in contexts where there's a sudden or substantial increase. While less formal than alternatives like 'arrive en masse,' it still finds acceptance in formal writing, particularly in a journalistic or reporting context. Additionally, the physical image of something literally being poured, like liquid, adds a vivid quality to its metaphorical uses.
