Prosiopesis (from Ancient Greek προσιώπησις prosiṓpēsis 'becoming silent') is a term coined by Otto Jespersen for pronouncing a word or phrase without vocalizing its initial sounds.
Jespersen introduced the idea in 1917;[1] he also discusses it in The Philosophy of Grammar (ISBN 0-226-39881-1; reprint 1992).
Prosiopesis is studied as a mode for originating interjections, which can shed light on their meaning.
This is similar to aposiopesis, where the ending of a sentence is deliberately excluded.
