The phrasal verb 'keep in' is generally more common in informal speech, though it might also appear in formal contexts, especially in written form. Its primary meaning is to maintain someone or something in a particular state or position. For example, teachers might use it to mean holding a student indoors, such as when a child is 'kept in' during lunchtime as a punishment or to complete work, which is more common in informal education conversations. Additionally, 'keep in' can refer to continuing to maintain a level of interest or engagement, such as in the sentence 'keep me in the loop.' It also finds use in contexts where it means to suppress emotions, like when someone tries to 'keep in their anger.' These varied usages suggest flexibility but note that their appropriateness can vary based on the context and level of formality required.
