Where this word comes from
Uncertain. De Vaan 2008 reconstructs Proto-Italic *gʷregs and Proto-Indo-European *gʷreg- (“group, herd”), and assumes it is cognate to Khotanese [script needed] (haṃ-grīs, “to gather, assemble”). A variant form of the same root, *g(ʷ)reg(ʷ)-, may possibly be the source of Ancient Greek γάργαρα (gárgara, “heaps, lots (of people, etc.)”) and Lithuanian gurguole (“mass, crowd”) and gurgulys (“chaos, confusion”). In contrast, Beekes views the Greek and Lithuanian terms as independent onomatopoeic formations, not cognates of each other. Matasović 2009 alternatively reconstructs Proto-Indo-European *greg- (“group, herd”), suggesting this comes from Proto-Indo-European *ger- or Proto-Indo-European *h₂ger- (“gather”). This reconstruction is based on treating grex and γάργαρα (gárgara) as cognates to Welsh gre (“herd”) and Old Irish graig (“horses”), from Proto-Celtic *gregi-: this cannot be inherited from a root starting with *gʷr-, since that would yield Proto-Celtic *br- (as in Proto-Celtic *brātus). However, it is debated whether the Celtic terms are cognate to or borrowed from Latin grex. Schrijver considers a connection with *h₂ger- doubtful but not completely impossible. Compare gremium and Proto-Germanic *krimmaną as other potential derivatives of *h₂ger-. Another potential cognate is Old Church Slavonic гръсть (grŭstĭ, “handful”).
