Usage Note

Decimoquinto is the ordinal numeral for 'fifteenth' and agrees in gender and number (decimoquinta, decimoquintos, decimoquintas). In formal writing, ordinals beyond tenth are often replaced by cardinal numbers (el 15 aniversario instead of el decimoquinto aniversario), making decimoquinto more common in literary and legal texts. It can also be written as two words: décimo quinto.

"Celebraron el decimoquinto aniversario de la empresa."
