Using さ as an interjection


I sometimes see a single さ at the end of a sentence, not being appended to an
adjective of either type, so I determined that this さ must be an interjection
or a 語尾｛ごび｝ of some type. Thus, what meaning does さ used as an interjection/語尾
convey, or is it more of a matter of personal preferences?
