Q2
What English words are also correctly
formed Roman numbers?
There are only two common, everyday words which are valid
Roman numbers - I (1) and mix (1009).
But there are seven words altogether - div (504), dix (509), I (1), li
(51), mi (1001), mix (1009), and xi (11).
The Scrabble Dictionary (third edition) also allows di (501), which
is really just a prefix.

Q4
How many English words can you make
using only letters from the Roman
numeral alphabet - C D I L M V X? (each
letter can be used more than once or not
at all)
There is no simple answer to this question. The bigger the
dictionary the more you find. Allowing only complete
words which are not proper nouns, I have found 35
using both the Oxford English Dictionary, second
edition 1989 (OEDII) and the Scrabble Dictionary,
based on Chamber's Dictionary, and now in its third
edition. If you count common abbreviations, allow
proper nouns, and include prefixes then I get up to 52.
The longest contains 6 letters.
