Usage Note
Veintiuno apocopates to veintiún directly before a masculine noun: veintiún años, but veintiuna chicas. The written accent on the final o marks stress. It is written as one word, unlike the tens-and-units compounds from 31 onwards (treinta y uno), which are three separate words.
Examples
"Tiene veintiún años recién cumplidos."
Natural Translation
He has just turned twenty-one.
