Ellipsis: Not saying what you mean

Ellipsis means leaving out certain words that are nevertheless understood by the reader though not expressed in the text. Ellipsis produces an economical and compact text. Hebrew has a greater tendency to ellipsis than English, as poetry has compared to prose. Paradoxically the word "ellipsis" comes from Greek meaning "leave in"! Presumably the notion is that ellipsis leaves a gap in the sentence!?
