How and when to use せや and its variants in Kansai-ben?


Here in Kansai I hear せや, せやねん, and せやな everywhere. I was wondering if anyone
could clarify the meaning and usage of these, as well as their equivalent in
more standard Japanese?

Additionally, are there any other variations based on せや that are used
commonly?




I think I say:

  * せや (or そうや) for そうよ / そうだ / Yes. / You're right. / Oh, (I just remember)... etc. 
  * せやねん (or そうやねん）for そうなのよ / そうなんだよ/ Exactly. / Yes, (actually you're right)... 
  * せやな (or そうやな) for そうね / そうだな/ You're right. / You may be right. / Let me see... etc. 

I also say:

  * せやで (or そうやで) for そうなのよ / そうなんだよ (Compared with せやねん, I think せやねん is more subjective and せやで sounds a bit more objective) 
  * せやて / せやって (or そうやて・そうやって) for そうだって / そうだってば / Right,(trust me, that's the truth...) / (sounds like you're trying to persuade or repeating what you've just said) 
  * せやかて (or そやかて) / せやけど (or そやけど) for そうだけど / それでも / そうだとしても / You're right, but... / You may be right, but... / You say so, but... 
  * せやし (or そやし) for だから / そうだから / so... / therefore... 
  * せやった (or そやった) for そうだった (the past tense of そうだ)
