The phrasal verb "pull away" is generally more common in informal use than in formal contexts as it is often applied in everyday conversations. It typically describes the action of starting to move away from a stationary position, especially with a vehicle, such as a car pulling away from a curb or stoplight. Additionally, it can describe someone emotionally or physically distancing themselves from others, which might be applicable in both personal and sometimes professional settings, although its informal connotation makes it less likely to appear in strictly formal texts. "Pull away" can also refer to gaining a lead or advantage over competitors, commonly used in sports or competitive situations, as in "She pulls away from the other runners." While these uses make it versatile, in formal documents, it might be replaced with more precise or less idiomatic alternatives.
