вреда

Etymology

Related to Old Church Slavonic врѣдъ m (vrědŭ, “wound, illness”), dialectal Bulgarian вред (vred) from Proto-Slavic *verdъ (“injury”), but not certainly how. The gender may have been changed in analogy with Bulgarian беда (beda, “trouble”) or, alternatively, the modern form could reflect the deverbal noun from the causative вредя (vredja).
