What comes after "primary" and "secondary"?

Have you ever said something like "the primary..., the secondary..."? What comes after that? I knew the next one started with a "t" but wasn't sure. Well AskOxford.com has the answer, the order goes as follows: primary = 1 secondary = 2 tertiary = 3 quaternary = 4 quinary = 5 senary = 6 septenary = 7 octonary = 8 nonary = 9 denary = 10
