Signification
Limiting your knowledge.
Contexte culturel
The phrase reflects 'nuchterheid' (sobriety/pragmatism). Dutch people value facts over speculation. In Flanders, the phrase is also common, but you might hear 'Dat is al wat ik weet' (dropping the -les). Speakers might add 'toch' at the end for emphasis or confirmation. Using this phrase is seen as professional boundary-setting, not as a lack of effort.
The 'Wat' Rule
Always use 'wat' after 'alles'. This is a high-frequency grammar rule that will make you sound much more native.
Don't be too blunt
If you say it too fast or without a smile, it can sound like you are annoyed. Add a 'hoor' at the end to soften it: 'Dat is alles wat ik weet, hoor!'
