"tal vez" vs "acaso"

Question

What's the difference between "tal vez" and "acaso"?

Answer 1

I was wondering about this today. From the SD dictionary, acaso is a lot more versatile in its uses than tal vez.

The word acaso seems to be a favorite for sayings like: por si acaso (just in case).

Yes, it does. - rac1, Nov 24, 2012

Answer 2

I think that few Spanish speakers would worry about which they use except for "por si acaso" which is not the same as plain "acaso". Obviously there are bound to be regional and even personal preferences but I think that they serve the same purpose.

I look forward to being put right if this is not so.
