The correct answer is "go on" and "catch up". You don't have to wait for me, go on, I'll catch up later with you.
These two phrasal verbs are fundamental in English, and they show up constantly in real conversation. "Go on" means to continue or proceed, while "catch up" means to reach someone who is ahead of you, either physically or in terms of progress. The mistake many learners make is mixing them up or reversing their order, but once you see them in context, the pattern locks in.
What does "go on" mean?
"Go on" has several uses. Most commonly, it means to continue what you are doing. If someone says, "Should I stop?" you might reply, "Go on, I'm listening." It can also mean to proceed to the next thing, like "After we finish this chapter, we'll go on to grammar." In the example above, "go on" means the speaker is telling their friend to move forward or continue their journey without waiting.
What does "catch up" mean?
"Catch up" means to reach someone who is ahead of you or to complete something you have fallen behind on. If you are walking slowly and your friend walks faster, you might say, "Wait, I'll catch up with you in a minute." You can also catch up on work, meaning you complete tasks you missed. In the phrase above, the speaker is saying they will reach their friend later.
Why learners mix these up
The confusion comes from the fact that both phrasal verbs involve movement or progress. A learner might think the pattern is "catch on" or "go up," but these combinations mean something entirely different. "Catch on" means to understand something, not to reach someone. "Go up" means to increase or move upward. The words "go" and "catch" each have their specific partners, and switching them breaks the meaning.
How to remember the difference
Think of it this way: if you are ahead and moving forward, you "go on." If you are behind and need to reach someone, you "catch up." The word "up" literally suggests moving toward someone, while "on" suggests forward motion. Once you connect the imagery to the words, the combination stays with you.
Practice these in real sentences
Here are real examples you would hear in English: "Don't wait for me at the station. You go on, and I'll catch up." Or: "She went on with her presentation while the latecomer caught up in the hallway." Another common one: "Go on without me. I have some things to finish, but I'll catch up with you later."
Build your phrasal verb skills through real speaking
Phrasal verbs live in conversation. Reading about them helps, but you learn them fastest when you use them with a real person who corrects you naturally. This is where speaking practice with native speakers changes everything. When you hear a native speaker say "go on" in context, and you respond using "catch up" correctly, the phrasal verb becomes part of how you think, not just a rule you memorize.
At PBC Languages, free language exchanges connect you with native English speakers who use phrasal verbs every day. These exchanges are genuinely free, always will be, and no money changes hands. You speak English for half the time, and your partner practices their native language with you for the other half. You are both teaching and learning at once. Beyond the exchanges, PBC Languages offers live classes in very small groups, with a maximum of 4 students, so you cannot hide. Everyone actually speaks. The experienced teachers chosen by PBC Languages weave phrasal verbs into natural conversation, not as isolated grammar points.
