Description

I read the phrasing "curious to why" instead of "curious as to why" somewhere and did some research on whether it's a common error and what its variants are.

I found it also happens with "unsure" and with most of the "wh- words" and "how".

Common false positives with "to what extent" or "degree" are avoided.
