grey (Spanish)

Where does "grey" come from?

The Spanish noun 'grey', meaning 'flock' or a group of believers, is inherited from Old Spanish 'grey'[1]. This form traces back to Latin 'gregem', an accusative of 'grex'[1]. Ultimately, these terms derive from Proto-Indo-European '*h₂ger-', meaning 'to assemble, gather together'[1].
