Sith fell out of common usage in the 16th century. 14th and 15th century mentions are plentiful and the presence of this word in such works as The Towneley Plays (which were performed up until the latter half of the 16th century) indicates that the word was still probably in use throughout the first half of the 16th century, mostly in various idioms and set expressions. The phrase “by siths” used to mean “at times, sometimes”.
- (obsolete) since.
