What is the longest word composed solely of Roman numeral letters?
The Divi-divi (Caesalpinia coriaria) is a tree native to southern Mexico. If we’ve got to count normal English words only, there is a 5-way tie for: civil, civic, livid, mimic, and vivid. Awesomely, these 5 words of 5 letters have 5 V’s among them, the Latin numeral for 5! There are also 5 words that have 7 letters, one of which is NOT a Roman numeral: civilly, codicil, divided, illicit, and vividly, but no words with 8 or more, even given one “free” letter.
