ORIGIN

Middle English: from Latin anniversarius ‘returning yearly,’ from annus ‘year’ + versus ‘turning.’

I should be talking to you about how you celebrated your 1 month anniversary as a newlywed but instead I'm trying not to cry, I know this won't be the first anniversary this year that will make me cry.
