🤖 AI Quick Answer
How do you politely say you don’t understand at work?
Say something like “I’m sorry, I didn’t quite catch that” or “Could you explain that one more time, please?” These phrases sound polite and professional, and most colleagues would much rather repeat themselves than have you make a mistake.
🔑 Key Vocabulary
| Word/Phrase | Meaning |
|---|---|
| Catch that | To hear or understand what someone said |

💬 Essential Phrases
“I’m sorry, I didn’t quite catch that.”
When to use: You couldn’t hear what someone said due to noise.
Example: “A forklift drives past while someone is talking. You say: ‘I’m sorry, I didn’t quite catch that.'”
Explains that you missed their words and prompts them to repeat.
“Could you explain that one more time, please?”
When to use: The instructions were too complicated to understand the first time.
Example: “The manager explains a new safety rule. You ask: ‘Could you explain that one more time, please?'”
A formal request for someone to repeat their instructions.
“Would you mind speaking a little slower?”
When to use: Someone is talking too fast for you to process the English.
Example: “A colleague is rushing through the handover. You ask: ‘Would you mind speaking a little slower?'”
Politely asks the speaker to reduce their pace so you can understand.
“I am not sure I follow — could you explain again?”
When to use: You understood the words but not the overall meaning.
Example: “Your manager explains a new process. You say: ‘I am not sure I follow — could you explain again?'”
More specific than “I don’t understand” — it focuses on losing the thread of the explanation.
“I want to make sure I do it right.”
When to use: Adding a reason after asking for clarification.
Example: “I’m sorry, could you explain the calibration part again? I want to make sure I do it right.”
Shows you are professional and care about quality, not just confused.
🏭 Real Workplace Scenario
Situation: Receiving complex instructions.
Manager: “…and then you need to calibrate the sensor before restarting.”
You: “I’m sorry, could you explain the calibration part again? I want to make sure I do it right.”
Manager: “Of course. First, you press this button…”
💡 Why this works: Adding “I want to make sure I do it right” shows you are professional and care about quality — it reframes the question as diligence, not confusion.

- Use a polite opener: “I’m sorry, I didn’t quite catch that”

🇬🇧 UK Workplace Tip
Asking for clarification is especially important for health and safety instructions. Never guess or nod along if you’re unsure — a few extra seconds asking a question is always worth it compared to a mistake or accident.
