Most managers are strong in general English. Both new and experienced managers hit the same wall. The words for managing people are different from the words for doing the work yourself.
You can explain a technical decision clearly. You can write a precise status update. You can hold your own in a client call. Then you are in a 1:1, trying to say why a deadline slipped, and the right word does not come. The gap is not confidence. It is a specific set of words you can learn. Native-speaking managers use these words without thinking. They have heard them in a hundred talks with their own team.
This is not a grammar problem. It is not a vocabulary-size problem either. Below, the words are grouped by the situation you are in, not by the alphabet.

Assigning and owning work
Most of what a manager does day to day is decide who does the work, and who answers for the result. English has two different words for this. Mixing them up causes real confusion.
Responsible describes who does the work. Accountable describes who owns the result, even if they did not do the work themselves. A manager can be accountable for a deadline that a team member is responsible for meeting. Saying "I'm responsible for the launch" when you mean "I'm accountable for the launch" makes your role sound smaller than it is. Saying it the other way makes someone else's role sound smaller.
Delegate means you hand off a task, along with the context and the power to decide. Handing off a task without those two things is closer to dumping it on someone. "I delegated the vendor talks to Priya" tells you she can make calls on her own. "I gave Priya the vendor thing" does not tell anyone what she is allowed to decide.

Understanding is only the first step.

People use three verbs for very different relationships. Each one is about someone's growth in a different way. Picking the wrong one changes what the other person expects from you.
Coach means you help someone get better at one specific thing. This is usually through direct feedback on their work. Mentor means you share broader experience and perspective, often without direct power over their day-to-day work. Manage covers the whole relationship. It includes both of the above, plus decisions about their role, pay, and rating. "I'm coaching her on presentation skills" is a narrower, more specific claim than "I'm mentoring her." Neither one is the same as "I manage her."
Calibrate, in a performance review, means you adjust your ratings against other managers' ratings. This keeps the same bar across the team. It's not just "thinking it over." "We calibrated the ratings across the team before we finalized them" describes one specific process. "We thought about it some more" does not.
Talking about performance
This is where an unclear word does the most damage. The word itself shapes how serious the talk sounds to the person hearing it.
Underperforming is a specific, documented claim: someone is not meeting a set bar, again and again. Struggling is softer and more short-term. It describes a rough patch, not always a pattern. Calling someone "underperforming" when you mean they had one bad month makes the talk feel more serious than you meant. Calling a real, ongoing pattern "struggling" can make it sound less serious than it really is.
A stretch goal is a target set on purpose above what people expect. Missing it is not meant to count as a failure. A regular target carries the normal expectation that you will meet it. If you present a stretch goal as a target, or the other way around, someone may feel like they failed when they did not, or may coast when they should not.
For the actual conversation — naming the fact, the impact, and the expectation, without softening it into vagueness or escalating it into a verdict — see How to Raise a Performance Concern With a Direct Report in English.
Day-to-day oversight
The line between staying informed and controlling someone's work too closely comes down to which word you use.
Oversee means staying informed and available, without directing every step. Micromanage means controlling the details of how work gets done, more than the situation needs. Almost nobody calls themselves a micromanager — people mostly use that word about someone else. That is exactly why it helps to know it well: "I oversee the migration" and "I'm micromanaging the migration" describe very different levels of involvement. Only one of them is usually what you meant to say.
Why this vocabulary is worth learning deliberately
None of these words are empty jargon. Each pair marks a real difference. It changes what the other person expects next. Saying "accountable" instead of "responsible" tells your manager something specific about your role. Saying "coach" instead of "manage" tells a direct report something specific about the talk ahead. Most non-native managers already know these words. The real problem is picking the right one in the moment. Without it, people default to a vaguer word that says less than they meant.
That precision is exactly what steady practice builds. Lyra Practice is built around workplace situations like the ones above -- 1:1s, performance talks, and delegation moments -- with feedback on whether the word you picked actually fits.
Frequently Asked Questions
What is business English for managers?
It's the specific words used in the people side of a manager's job: assigning and owning work, coaching, performance talks, and day-to-day oversight. This is separate from the technical or functional words for whatever the team actually does. Words like accountable, delegate, coach, and underperforming carry exact meanings here, and they're worth learning on purpose.
What vocabulary do managers actually need at work?
Based on real management cases, the most useful words fall into four groups: ownership words (responsible vs. accountable, delegate vs. dump), growth words (coach vs. mentor vs. manage, calibrate), performance words (underperforming vs. struggling, stretch goal vs. target), and oversight words (oversee vs. micromanage). These come up in nearly every 1:1 and performance cycle, far more than generic "leadership" words.
How is this different from general leadership vocabulary?
General leadership content tends to teach style: how to sound confident, how to run a meeting. This guide is narrower and more concrete. It covers specific word pairs. Choosing the wrong one changes what the other person understands, no matter how confident you sound.
