A2 Expression ニュートラル

Dat weet ik niet

I do not know that

意味

Stating lack of knowledge.

🌍

文化的背景

Dutch people value honesty. Saying 'Dat weet ik niet' is better than guessing and being wrong. Flemish speakers use the same phrase, but might sound slightly softer in tone. They might use 'Ik zou het niet weten' more often. In Surinamese Dutch, the phrase is common but might be followed by more expressive body language or 'no' (from Sranan Tongo). In Dutch tech companies, 'Dat weet ik niet' is often followed by '...maar ik zoek het uit' (but I'll find out).

💡

Add 'eigenlijk'

Adding 'eigenlijk' (actually) makes you sound much more like a native speaker: 'Dat weet ik eigenlijk niet.'

⚠️

Don't just say 'Nee'

Just saying 'Nee' can be too blunt. 'Dat weet ik niet' is much more polite.

The 'Dat' vs 'Het' trick

Use 'Dat' when you want to point specifically to the question asked. Use 'Het' for a more general 'I don't know'.
