Yes. LinguaFlow is GDPR-compliant, encrypts data in transit and at rest, and lets you export or permanently delete your data anytime.

Can I use it for group classes?

It’s built for one-on-one tutoring but works for small groups — create a profile per learner and generate level-appropriate content for each.

Business English Vocabulary and Expressions

Name: LinguaFlow
Author: LinguaFlow

General vocabulary lessons rarely prepare a student for the specific language of a workplace. A student can know thousands of everyday words and still freeze the first time a colleague says "let's circle back on this" or asks them to "touch base" before Friday. Business English has its own register, part fixed vocabulary, part idiom, and it's worth teaching as its own category rather than assuming it'll come up naturally in general conversation practice.

This is a working reference: core vocabulary by context, common idioms and expressions, and how to actually teach this so it sticks rather than just gets recognized on a list.

Core Vocabulary by Context

Meetings

Agenda: the list of topics a meeting will cover. "Can you send the agenda before the call?"
Action item: a specific task someone commits to after a meeting. "Let's list the action items before we wrap up."
Stakeholder: someone with an interest in a decision or project's outcome. "We need buy-in from all the stakeholders first."
Follow up: to continue a conversation or task after the initial meeting. "I'll follow up with you by email."
Table (a topic): to postpone discussing something. "Let's table that until next week's meeting."
Consensus: general agreement among a group. "We reached consensus on the new schedule."

Email and Written Communication

CC / BCC: copying someone on an email, visibly or invisibly. "I'll CC the whole team on this."
Per my last email: a (often pointed) way of referring back to something already said. "Per my last email, the deadline is Friday."
Attach / attachment: a file sent along with an email. "Please find the report attached."
Out of office: an automatic reply while someone is away. "I'm out of office until Monday."
Circle back: to return to a topic later. "Let's circle back on pricing once the team weighs in."
Flag: to bring attention to something, often a concern. "I wanted to flag a potential issue with the timeline."

Negotiation and Deals

Ballpark figure: a rough estimate. "Can you give me a ballpark figure before we finalize the contract?"
Bottom line: the final, most essential point, often financial. "What's the bottom line on cost?"
Win-win: an outcome good for both sides. "We're looking for a win-win on this deal."
Deal-breaker: a condition that would end negotiations if not met. "Payment terms are a deal-breaker for us."
Leverage: an advantage used in negotiation. "We don't have much leverage here since they have other suppliers."
Concession: something given up to reach agreement. "They made a concession on delivery time."

Presentations

Key takeaway: the main point an audience should remember. "The key takeaway is that costs are down 12%."
Deck: a slide presentation. "I'll send you the deck before the meeting."
Q&A: the question-and-answer segment after a presentation. "We'll open it up for Q&A at the end."
Drill down: to examine something in more detail. "Let's drill down into the regional numbers."
Big picture: the overall context, as opposed to details. "Zooming out to the big picture, we're on track for the year."

Performance and Feedback

KPI (key performance indicator): a measurable target used to track success. "Our main KPI this quarter is customer retention."
Constructive feedback: criticism intended to help someone improve. "I have some constructive feedback on the report."
Onboarding: the process of integrating a new employee. "Onboarding usually takes about two weeks."
Touch base: to check in briefly. "Let's touch base at the end of the week."
Underperform: to do worse than expected. "Sales underperformed this quarter."

Common Business Idioms Worth Teaching Directly

Idioms like these rarely appear in general vocabulary lists, but they show up constantly in real workplace conversation:

On the same page: in agreement or mutual understanding. "Before we proceed, let's make sure we're on the same page."
Low-hanging fruit: an easy win, tackled first. "Let's start with the low-hanging fruit before the harder problems."
Think outside the box: to think creatively, beyond usual approaches. "We need to think outside the box on this one."
Get the ball rolling: to start something. "Let's get the ball rolling on the new project."
Back to the drawing board: to start over after a failed attempt. "That approach didn't work, back to the drawing board."
Bring something to the table: to contribute value or a skill. "She brings a lot of experience to the table."
The elephant in the room: an obvious problem nobody wants to address directly. "Let's address the elephant in the room: the budget."
Move the needle: to make a meaningful difference. "This campaign really moved the needle on brand awareness."

How to Actually Teach This So It Sticks

Match idiom introduction to level, not enthusiasm. Idioms are genuinely useful, but they're mostly a B2+ skill. Introducing them too early, before a student has a solid grasp of literal, direct business vocabulary, tends to create confusion rather than fluency. See our CEFR guide for what's realistic at each level.

Give every term a real example sentence, not just a definition. A translated word list teaches recognition, not usage. This same principle applies across any complete lesson materials set: context is what makes vocabulary usable, not just known.

Practice the vocabulary inside a real scenario, not as an isolated list. Pairing these terms with an actual business conversation topic or set of business conversation questions gives the vocabulary somewhere real to live, instead of sitting on a list the student memorizes and forgets.

Distinguish formal from informal register explicitly. "Touch base" and "circle back" are casual enough for most teams but might read as too informal in a very traditional or hierarchical workplace. Flag this distinction directly rather than assuming a student will pick up on it themselves.

Common Mistakes When Teaching Business Vocabulary

Treating idioms and core vocabulary as one category. They need different teaching approaches. Core terms (stakeholder, agenda, KPI) can usually be taught directly; idioms need more context and repetition to land naturally.

No example sentence, just a translation. This is the single most common gap, and it's the difference between a student who can recognize a term and one who can actually use it in a meeting.

Ignoring the student's actual industry. A student in finance and a student in tech will encounter genuinely different vocabulary day to day. Generic business vocabulary is a reasonable starting point, but it shouldn't be the whole plan for long.

Building Vocabulary Around a Specific Student's Work

Generic business vocabulary is useful groundwork, but a student's actual job usually calls for more specific terms than any general list can cover. LinguaFlow generates vocabulary personalized to each student's real goals and industry, paired with the context and example sentences that make it stick, not just a translated word list.

Frequently Asked Questions

At what level should business idioms be introduced? Generally B2 and above. Below that, students usually benefit more from mastering direct, literal business vocabulary first.

How many new terms should one lesson introduce? Around 8 to 12, consistent with vocabulary teaching generally. More than that and there's rarely enough practice time left to make them stick.

Should I teach American and British business terms differently? Only where they genuinely diverge (for example, some scheduling and email conventions), and it's worth flagging when a term is regionally specific rather than universal.

Is memorizing a list of idioms actually useful? Not on its own. Recognition from a list is a starting point, but usage comes from seeing and practicing the term inside a real scenario, not from memorization alone.
