Per Brückner and Sławski (accepted by Trubačev /ESSJa/), a doublet of *krupъ. Derksen distinguishes the two lemmas, but accepts that they have intermingled at later time.
Further origin probably from the root of Proto-Balto-Slavic *krúptei (“to contract, to crumple?”), whence Lithuanian krùpti (“to get scabby”), Latvian krupt (“to frawn”), with inchoatic nasal infix. Ultimately from Proto-Indo-European *krewp-, an extension of *(s)ker- (“to bend, to crook”). Akin to Proto-Germanic *hreubaz (“rough, scabby”).
