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:
“On the death of a friend, we should consider that the fates through confidence have devolved on us the task of a double living, that we have henceforth to fulfill the promise of our friends life also, in our own, to the world.”
—Henry David Thoreau (18171862)
