The double hyphen (＝, ゠, or ⸗) is a punctuation mark that consists of two parallel hyphens. It is not to be confused with two consecutive hyphens (--), which usually represents an em dash (—) or en dash (–). In order to avoid its being confused with the equals sign (=), the double hyphen is often sheared slightly.
Famous quotes containing the word double:
“Hollywood held this double lure for me, tremendous sums of money for work that required no more effort than a game of pinochle.”
—Ben Hecht (1893–1964)
