Hanging punctuation or exdentation is a way of typesetting punctuation marks and bullet points, most commonly quotation marks and hyphens, so that they do not disrupt the 'flow' of a body of text or 'break' the margin of alignment.
A hanging quote is way of setting the quotation marks.
Explanation:
Hanging punctuation, also known as exdentation, refers to a certain way of setting the quotation marks or inverted commas, not incorporated into the block of the text but hanging in the margin of it so that the flux of such text do not be disturbed.
