I was interested in determining words to describe ordinal Latinate series numbering above orders of 10 (i.e., "denary").
I found "duodenary", which makes sense based on the latin root duodecim, meaning 'twelve.' (see also etymology of the duodenum of the small intestine -- duodeni, meaning 'in twelves.').
However, I found no evidence of other ordinal numbering adjectives other than that for 20.
I have two questions:
Here, here and here suggest that "vigenary" is the Latinate ordinal term for "twentieth" (or "of the twentieth order"). However, none of these sources come across as legitimate. Can anyone confirm for me (through a more trustworthy and proper source) that "vigenary" is in fact the proper word to use here?
Do other Latinate ordinal adjectives (for orders > 10) exist?
