What does haeyo (해요) mean?

Edit: Jesus Christ. I didn't mean for this question to come out as a 'I have no interest in Korean, I just want to know' question. I have been studying Korean for almost a year now and now I can say anything you ask me to, including read Hangul, know the Korean grammar, make phrases informal and formal, and the basic Korean word order including the particles. None of the books I read mentioned what the literal translation for 'haeyo' is. Not even web searches or google translate. I had an IDEA that 'haeyo' meant something to do since I already know that 하다 (dictionary form) means 'to do', but I wanted to be 100% sure for future occasions.
