What are the opposite words for xii?

Sadly, we can't write a 100-word article on antonyms for the word "XII" since it is actually a Roman numeral that stands for 12. Antonyms, by definition, are words that have opposite meanings. It doesn't typically hold true for numerical figures. In Roman numerals, "XII" simply means "twelve" and is commonly used in watches, clocks, and calendars to refer to 12 o'clock or the twelfth month of the year. For example, "December" is the twelfth month, and "August" is the eighth month. There isn't much else to write about antonyms in this context.
