Sin embargo vs. Empero

Question

I know that that both can be used to say 'however". But are they completely interchangeable, or are there any differences in how they should be used?

Answer 1

You're right, they are interchangeable, but sin embargo is much more common. You almost never hear empero said (at least, I don't). It is mainly used in writing.

I'd say only in (very) formal writing. - lazarus1907, Aug 20, 2010

I've only come across it once, myself. - MacFadden, Aug 20, 2010
