What is the Roman numeral for 19?

Answer 1

Under today's modern rules now governing the Roman numeral system 19 is now considered to be XIX but the ancient Romans would have probably notated it as XVIIII or as IXX because their Latin words are 'novemdecim' meaning nineteen and 'undeviginti' meaning one from twenty respectively but there is no Latin word for the equivalent of XIX

Latin was the language spoken by the ancient Romans.

Answer 2

The Roman Numeral for 19 is XIX (10 + (10 - 1)).
