Hypenation of twenty-first century
Posted: 05 Sep 2019, 10:08
I recently came across this and it stumps me. I'm accustomed writing the word as "TWENTY-FIRST CENTURY" with one hyphen only. Imagine my shock when I saw the word with two hyphens! Only the numbers are joined because the digits are when written as 21st. So says my British schooling.
Any thoughts?
