Last week the origins of the word agora came up in conversation and I thought I’d find out more.
An agora was a place of gathering or marketplace in Ancient Greece. It comes from the Ancient Greek ἀγείρω [ageirō] (I gather, collect), from the Proto-Indo-European *ger- (to assemble, gather together), which is the root of the English words gregarious, aggregate, congregate, egregious, segregate, allegory, category, and panegyric, via the Latin gregārius (of the herd, common), which comes from grex (herd, flock).
In Romance languages, such as Aragonese, Asuturian, Galician, Ladino, Mirandese and Portuguese, the word agora is also found, but it means ‘now’ and comes from the Latin expression hāc hōra (‘this hour’). The Spanish word ahora (now) comes from the same root. hōra comes from the Ancient Greek ὥρα [hōra] (time, season, year), from the Proto-Indo-European *yōr-ā, a suffixed form of *yēr/*yeh₁r- (year, season), which is the root of the English word year, and the words for year in many other Indo-European languages.

The friend who asked about agora wondered whether the Welsh word agor (open) might come from the same root. I haven’t been able to find any information about this. Does anybody know?
