According to Derksen, inherited from Proto-Balto-Slavic *kálˀdāˀ, from Proto-Indo-European *kold-eh₂; cognate with Proto-Germanic *hultą (“wood”) and Ancient Greek κλάδος (kládos, “branch, shoot”). Ultimately may be from the root of *kolti, from PIE *kelh₂- (“to beat, chop, hew”).
The /ɡ/ of Old Church Slavonic глада (glada) is perhaps modified to resemble гладъкъ (gladŭkŭ, “smooth; even”), гладити (gladiti, “to stroke; to smooth, polish”), or otherwise unexplained.

* -asъ is the expected Balto-Slavic form but is found only in some Old Czech documents; -axъ is found everywhere else and is formed by analogy with other locative plurals in -xъ.
** The second form occurs in languages that contract early across /j/ (e.g. Czech), while the first form occurs in languages that do not (e.g. Russian).
