I often hear native speakers say for some reason, but I think reason is usually a countable noun and "some reasons" can have the meaning of "an unspecified number of reasons". I think for some reasons ought to be a correct form of it.
What's your comment?
Is "for some reasons" used in everyday English? If it is, what's the difference between it and "for some reason"?
(The answer to the question that people think is a duplicate of mine doesn't help, because it lists both singular and plural words used with "some".)
