prüfen

Etymology
From (13th c.), originally restricted to Central German. Ultimately from and hence a. The form with umlaut (and also  in the past tense ) suggests a, whence also 🇨🇬, 🇨🇬. The late attestation on the other hand speaks in favour of a later borrowing from. In this case the word may have passed through, which would explain the umlaut as analogical (cf. the lack of long umlaut vowels in western Dutch vs. their presence in eastern dialects).
