An economical or condensed expression that represents a complete statement or command (eg: Indeed. / Been there. Done that. / Enough on that subject. / Now, to proceed to your next point.); and is therefore concluded by a period. Elliptical expressions often occur as answers to questions or as transitional phrases. Unlike an elliptical expression, a "sentence fragment" is a word, phrase, or clause that is incomplete; and should either be joined with other elements to form a complete sentence, or punctuated as a fragment (v: ellipses). See phrase, clause, sentence, period, punctuation, parts of speech, stylebook.
