Is "scythe" ever pronouced like "sith"?

It’s got a long I. It rhymes with tithe

No. It is s (long i) th (as in “the”).

No. Three strikes, you’re out.

It’s pronounced as sith if it is spelled that way, as in Sith Lord (from the movie)

Spelled scythe, it’s a farm implement and pronounced with a long i as in eyes.

short i as in
