What is the role of そうよ in そうよ存外怖くはないわ?

Question

I heard そうよ存外怖くはないわ in a song, but I don't get the meaning of そうよ.

Answer 1

そうよ just means "That's right" or "Yes" (or sometimes "No" in a negative sentence). そう means "so" or "that way", and よ is a sentence-end particle (sounds feminine because it directly follows a noun).

If this is taken from this song, this そうよ is simply used to emphasize 怖くはない — "No, I'm not afraid". (Please always try to include the link to the original song; it's often difficult to interpret a line from a song unless we have the whole context.)
