vt.

Where alternate spellings or pronunciations are given, alt.
separates two possibilities with nearly equal distribution, while
var. prefixes one that is markedly less common than the primary.

Where a term can be attributed to a particular subculture or is known
to have originated there, we have tried to so indicate. Here is a
list of abbreviations used in etymologies:
