Possible Duplicate:
If annual means one year, is there any word for two,three, four.. year

...like Olympic Games or World Cup. Is there a word to describe their periodical characteristic or just simply "every 4 year"? There are words like Annual, Biennial, Triennial (every 1, 2, 3 years) but Quadennial seems not to be a valid word.

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

I see the word quadrennial in that question. But it does not appear in Oxford or Cambridge dictionaries. Is it OK if I use it in academic writing? – KiL Aug 29 '12 at 5:01

Quadrennial is the word.
