I know you could use the word wants, like "He WANTS to go with you" and it wouldn't have an apostrophe. But with an apostrophe, it says it's spelled wrong in Word, and in the Google search bar. However, in Ke$ha's song, What the Hell (is wrong with me), she sings the line, "And all I really want's a boyfriend", with it being a conjunction for "want is", like, "All I really want is a boyfriend." So, in this case, could "want's" become a word?
I'm asking because I make Kesha lyric videos, and the soul purpose I started was because I hate lyric videos with bad grammar, and now I feel conflicted because I'm not sure. I know a lot of people hate her, but this isn't about her, I just used her song lyrics for the example. Thank you so much for answering! :)
