Reconstruction:Proto-Slavic/korpъ

Uncertain. Opinions split between:

• Sobolevsky, Berneker: Of native origin, substantivized from the root of Proto-Slavic *korpa (“toad”), Ukrainian коропа́вий (koropávyj, “scrubby”) (< *korpavъ). Possibly further akin to Lithuanian karpà (“wart”), Lithuanian kar̃pa (“callus”).
• Hirt, Uhlenbeck, Šakhmatov: Borrowed from Germanic, perhaps Gothic *𐌺𐌰𐍂𐍀𐌰 (*karpa) or Old High German karpho, karpo, karpfo. The later is the source of terms without liquid metathesis: Polish karp, Russian карп (karp), etc (borrowed in post-Common Slavic period). Also borrowed in Lithuanian kárpa (“carp”).
• Meyer, Machek: From a pre-Indo-European substrate, spoken in the Danube region.

In either case, related to Old High German karpo, Late Latin carpa. Vasmer excludes Slavic origin for the Germanic terms (and from there for Latin), however, leaves as a possibility spread from some paleo-Balkan or paleo-Pannonian Indo-European dialect.

South Slavic descendants point towards acute root *kőrpъ,[1] while East Slavic towards lax *kȍrpъ > Old East Slavic ко́ропъ (kóropŭ).
