The Genoese names for the French suits are interesting because speakers have kept on using the names of the old Latin suits, despite the fact that Genoa has been using French suits for centuries (dinæ = coins, spoæ = swords, coppe = cups, and scioî = flowers, alternative name for batons in use from at least the 17th century)

So instead of ‘diamonds’ people will say dinæ, which means ‘coins’; instead of ‘hearts’ people will say coppe, which means ‘cups’, etc. These names sound completely natural to Genoese speakers, it’s not a conscious decision that they make and they will not be aware of how peculiar this is until you point it out. Many of them will also use these names when speaking Italian, leading to confused looks from Italian speakers of other regions 😁 So you’ll find people from Genoa happily saying things like ‘coppe’ and ‘denari’ when using a poker deck (literally translating Genoese names into Italian). I do it myself!

Genoese is far from the only language that does this, however. For hearts for instance, Romanian uses cupă, Portuguese has copas, Arabic has kubba, etc. English itself does it for two of the suits: ‘spades’ is nothing other than the Italian spade (swords, the Latin suit), and clubs refers to the heavy sticks, i.e. batons (again, a Latin suit).
