word choice - When women use わ at the end of a sentence, is it different from よ?

My understanding of using わ at the end of a sentence is that it's essentially just for emphasis, just like using よ, and that only women can use it.

However, as far as I know, women can, and often do, use よ as well.

So is there a difference in meaning, nuance, or context which would make a woman choose to use わ instead of よ?

Answer

• よ expresses that the speaker assumes that the recipient does not know what is said.


• わ does not have such implication, and it just adds feminine flavour to the sentence.
