Yiddish: One word doesn't stick to another.

It's incoherent. It doesn't make sense.  SOURCE: Stutchkoff, Der Oytser fun der Yidisher Shprakh.  Compare:

Es klept zikh vi di reyd fun a meturef. | .עס קלעפּט זיך ווי די רייד פֿון אַ מטורף
It makes as much sense as the talk of a madman.

SOURCE: Stutchkoff, Der Oytser fun der Yidisher Shprakh

עס קלעפּט זיך ניט אַ וואָרט צו אַ וואָרט.

Es klept zikh nit a vort tsu a vort.

One word doesn't stick to another.
