m not sure, but maybe Duo is more specific for *coup doeil* or glance.
maybe regarde can be used on that sense..
but I`m not sure or i forgot some past lessons....
maybe some native french people here can answer this very relevant question for us who are trying to learn french
Honestly, there is just no percentage at all in asking why any particular word is masculine or feminine. Don't waste energy on fretting about it.
(Although, as it happens, "ion" endings are very, very likely to indicate feminine - it's probably more reliable than most rules about gender of French words.)
Thanks. The -ion definition you gave is the sort of thing for which I was looking. I am not concerned at all about historical words from yestercentury so to speak but rather recently introduced words. Assuming the process is not random, some institution or authority would have some rationale in their decision-making I would believe .
