Etymology of names of playing cards? According to the Japanese wikipedia, the playing cards ("trump") are named as follows (written in Japanese in katakana): A: Ace 2: Deuce **3: _torei_** **4: _keito_** **5: _shinku_** **6: _saisu_** 7: Seven 8: Eight 9: Nine 10: Ten J: Jack Q: Queen K: King It's quite clear that many names among those are from English. Those in bold type here are quite etymologically obscure. Does anyone know about their origins?

That Japanese Wikipedia entry says

> " **** 1236"

and English Wikipedia entry about dice says the following:

> "While the terms ace, deuce, trey, cater, cinque and sice have been made obsolete by one to six, they are still used by some professional gamblers to designate different sides of the dice. Ace is from the Latin as, meaning "a unit";[18] the others are 2 to 6 in old French.[19]".

So, these names were borrowed from English (ultimately from old French). Aside from etymology, these are completely obsolete and most Japanese don't even know them.
