The phrasal verb "go with" is predominantly used in informal speech, though it can occasionally appear in semi-formal contexts. It is highly versatile, serving multiple functions. Commonly, "go with" is used to indicate accompaniment, either physically, as in choosing to accompany someone (“I'll go with you to the store”), or metaphorically, as in supporting someone’s decision or idea. In another context, it signifies compatibility or suitability, often regarding aesthetics or choice (“Those shoes go with that dress”). Additionally, it is colloquially employed to mean choosing or selecting an option over others ("I’ll go with the steak for dinner"). While its usage is broad, it's less likely to be found in strictly formal settings, such as academic writing. The phrasal verb's contextual flexibility makes it a staple in everyday English conversation.
