Synonymous with and pronounced the same as "enby."
Sometimes "nb" is used to abbreviate "non-binary," which is not entirely correct. "Nb" is already the abbreviation for "non-black;" so in order to distinguish between the two meanings, "nby" or "enby" is much more encouraged and should be used in place of "nb" when referring to non-binary people in shorthand.
