Phrasal verbs cause a specific kind of trouble that other vocabulary doesn't. With most words, if you know the parts, you can guess the meaning. Phrasal verbs break that rule on purpose: "loop in" has almost nothing to do with loops, "chime in" has nothing to do with bells, and "push back" as a noun means resistance, while "push back" as a verb means to resist or to delay a date — two different things depending on how it's used.
That unpredictability is exactly why they're worth learning deliberately rather than picking up by accident. They're also not optional: phrasal verbs show up constantly in spoken workplace English, including from senior people, which means avoiding them entirely doesn't read as more formal — it just reads as slightly stiff.
Here are the ones that actually come up in professional contexts, not the huge general-English lists most phrasal verb guides default to.
Loop in — bring someone into a conversation or decision
"I should have looped in the design lead before sending that mockup to the client."
The person being looped in wasn't part of the conversation yet; the verb is the act of including them, usually before a decision moves too far without their input.

Push back — resist, or delay
"Legal pushed back on the contract language."
"Can we push back the launch by a week?"
This is the phrasal verb most likely to trip someone up, because the same two words carry two unrelated meanings depending on context: resisting a decision, or delaying a date. Native speakers switch between them without noticing; non-native speakers often default to only one and get misread in the other context.

Chime in — join a conversation briefly
"Feel free to chime in if you see it differently."
Chime in is lighter than "interrupt" or "add a comment" — it implies a short, natural contribution, not taking over the conversation. It's often used as an invitation ("feel free to chime in") as much as a description of what someone did.

Strike up — start, usually a conversation or relationship
"He struck up an easy rapport with the new hire during the airport layover on the way to the conference."
Strike up specifically suggests something starting naturally or spontaneously, not through a formal process. "We started a conversation" is neutral; "we struck up a conversation" implies it happened easily, almost by chance.
Full breakdown: what "strike up" means at work.
Drive home — make sure a point is fully understood
"One angry customer quote in the deck drove home the churn risk more than any of the survey numbers did."
Drive home is about landing a point, not just stating it — it implies the point is now understood and remembered, not just technically communicated. It's frequently used in the passive sense above, with the point itself as the subject, which is a pattern non-native speakers often avoid without realizing it's the more natural phrasing.

Why phrasal verbs are worth the specific effort
Two things make phrasal verbs harder than ordinary vocabulary, and both are reasons to practice them deliberately rather than hope they'll click from exposure.
The first is that the meaning is genuinely non-compositional — you can know every individual word and still not be able to guess the phrase. Reading widely helps eventually, but it's a slow way to acquire something this arbitrary.
The second is register. Phrasal verbs sit in an unusual place: they're common in spoken professional English, including from executives and senior leaders, but they can also sound casual or imprecise in formal written documents. Knowing when "push back" is exactly the right word and when "raise a formal objection" is the better one is a register judgment, not just a vocabulary one — and it's the kind of judgment that only comes from producing the phrase in context and getting feedback on whether it fit.
