weißt du
The German phrase for "you know" is weißt du.
As an interjection, weißt du acts as a filler or a hesitation marker, similar to how "you know" is used in English to signify a pause in speech. In this context, it is almost exclusively used in informal, spoken German.
Meaning: expression signifying a pause or hesitation (intj)
How does it change in a sentence?
weißt du is the informal singular version of "you know" and is used when addressing one person whom you know well.
Did you know?
- The word du is a direct linguistic relative of the archaic English 'thou'. Both evolved from the same Proto-Germanic root used to address a single person familiarly.
- German has a specific term, Füllwort, which literally means 'filling word', to describe terms like weißt du that occupy space without adding meaning.
- While weißt du is a filler, using the formal wissen Sie as a filler can sound overly stiff or sarcastic to native speakers, as formal language rarely uses hesitation markers.
