Ran across this yesterday, figured I'd pass it along based on my previous post on this word:

Aposiopesis ( = "hushing") is the abrupt termination of a sentence whose ending may be inferred from tone or gesture, or gathered from what has gone before. Examples may be seen in Lu 13.9; Lu 19.42; Jn 6.62; Ac 23.9.
