Meaning
Used when you cannot comprehend what is being said or explained.
Cultural Background
Americans value directness. If you don't understand, it's better to say it immediately. People will not think you are unintelligent; they will think you are being efficient. British speakers often use 'politeness markers' like 'I'm sorry' or 'I'm afraid' to soften the phrase. Saying just 'I don't understand' might sound a bit too blunt. When speaking English with Japanese colleagues, they may nod while you speak. This often means 'I am listening,' not 'I understand.' You may need to ask 'Do you understand?' gently. In Germany, clarity is key. If you say 'I don't understand,' a German speaker will likely give you a very detailed, logical explanation. They appreciate the honesty.
Be Specific
Instead of just saying 'I don't understand,' try saying 'I don't understand this word' or 'I don't understand the second part.'
Don't just nod
Many learners nod 'yes' when they are confused. This stops you from learning! It is always better to say you don't understand.
