You’ve got that mixed up (: di is Greek, bi is latin. You are correct about Latin prefixes being uni, bi, tri, and quad. Think of the word bicentennial, it is Latin based.
Yeah, I actually mixed it up with du (and I also mixed up cardinal and multiple prefixes). So to correct, in Latin it should be: simcaprio, bicaprio, tercaprio, quatercaprio etc…
OP, please title your posts something more descriptive/creative. This isn’t facebook, and someone might want to search for this pic at some point in the future
