Punctuation permitted to appear beyond the edges of the margins, rather than retained within the normal text area. A typographical style where punctuation at the end of flush-right lines is placed beyond the margin in order to ensure a clean and precise paragraph edge. See also MARGIN PUNCTUATION
In justified type, punctuation set just outside the measure, to achieve optical alignment.
Punctuation, very often speech-marks, placed in the margin oversized for the same effect as a drop-cap.
