"Stay out" is a phrasal verb more commonly used in informal contexts, though it can occasionally appear in semi-formal settings, depending on the discussion. This phrase is primarily used to advise or instruct someone to remain outside of a particular place or to refrain from becoming involved in a particular situation. In everyday conversation, it can be applied to various scenarios, such as a parent telling their child to "stay out of trouble," or a friend advising another to "stay out of a heated argument." "Stay out" carries the implication of distancing oneself from something potentially problematic or preferred to be avoided. While not typically used in highly formal writing or speech, this phrasal verb is effective in conveying a clear, straightforward message in relatable terms.
