I would like to start a sentence with "But nothing compares to..." and it seems like I should place a comma between "but" and "nothing."
But when I say it aloud, there's no pause there at all, and it all seems to be one phrase. In fact, adding the comma seems to change the meaning.
"But nothing compares to your beauty." - I've seen some beautiful things, but you're the most beautiful.
"But, nothing compares to your beauty." - You've got some faults, but at least you're beautiful.
Should there be a comma there, or not?
