The phrasal verb 'blow in' is typically used in informal contexts rather than formal speech. It is commonly employed to describe the act of someone arriving suddenly or unexpectedly, often without warning, as if blown in by the wind. For example, 'She just blew in from New York without telling anyone.' This usage connotes a casual or sudden arrival that does not involve the meticulous planning often associated with formal events. The term can further imply a sense of surprise or disruption, depending on the context. Additionally, 'blow in' can sometimes refer to the act of blowing something into a space, such as air or electricity, though this usage is less common. Overall, 'blow in' tends to appear more in conversational English and literature than in formal writing or professional settings.
