Category talk:Saltires couped in heraldry

What is this doing here?

Firstly, what is a "Flanchis"? By convention, we are supposed to use plurals for the names of categories, so the singular would be a Flanchi. What is a Flanchi? I have never heard of one, certainly not in English speaking heraldry.
Secondly, why is this category a sub-category of Crosses? What we are seeing are not crosses, they are saltires couped. Only if they were on a bend could they be classed as crosses - in all other instances, they are not crosses, but saltires couped. Kiltpin (talk) 14:30, 2 January 2016 (UTC)

It's a French heraldic term: de:Flanchis, [1] and [2]. Category:Saltires in heraldry is a subcategory of Category:Crosses in heraldry by type aswell, so why shouldn't flanchis be a subgroup of crosses? They're both derived from the Saint Andrew's cross. Cycn (talk) 11:55, 3 March 2016 (UTC)

Correct me if I am wrong, but don't we have a convention that all categories in Wikimedia Commons 'in heraldry' are to be in the English language? Both the Cross and the Saltire are honourable ordinaries in their own right and neither one should be a sub-category of the other. They both have equal standing and neither one is subordinate to the other. Kiltpin (talk) 11:58, 4 March 2016 (UTC)
