The phrasal verb "creep into" is primarily used in informal contexts and is often used to describe a situation where something gradually and often subtly begins to become a part of something else. This phrasal verb is frequently utilized in both spoken and written language to describe unwanted or unanticipated elements entering into an environment, thought process, or system. Common usage patterns include contexts like feelings (e.g., fear creeping into one's mind), errors creeping into a process, or ideas creeping into popular culture. While "creep into" is not typically found in formal written texts, its utility remains in highlighting the slow and barely noticeable nature of the incursion it describes. It conveys a sense of stealth and gradualness, often carrying a slightly negative connotation, suggesting an invasive or insidious quality about the thing that is developing.
