I've always been taught that 'irrelevant' is not a word, yet when I look it up on the research dictionary(AOL feature, which may be why...) it is found. However, in a regular, college dictionary, 'irrelevant' and 'irrelevance' are both not found.
So I am curious, is 'irrelevant' and/or 'irrelevance' a real word or one that belongs here?
I've made a mistake. I confused 'irrelevant' with 'irregardless.' My apologies.
