Phrasal Verb: Catch Up With / Run Into

Catch up with and run into are two common English phrasal verbs related to people and progress. This lesson explains both with clear examples. Catch up with means to reach the same level as someone or something, often used for academic or professional progress, as in I studied hard to catch up with my classmates. Run into means to meet someone by chance, unexpectedly, as in I ran into an old friend at the mall, describing a surprise encounter. The key difference is that catch up with is about closing a gap in progress or knowledge, while run into is about an unplanned meeting. Both phrasal verbs are common in everyday English, especially when talking about relationships, school, or unexpected encounters. Learning them together helps you describe both effort and coincidence naturally in conversation.
