v

v

n. “Version.” See also VERSION NUMBER. Compare “v.” (with a trailing dot) for VERB.

NOTE: Depending on whether you're of the opinion that it's either an abbreviation or a single-letter acronym, it may be written either with (v.) or without (v) a trailing dot (.).

Acronyms are normally written in all-caps. However, despite the typically lower-case usage (as in, “v 2.0”), I favor the latter interpretation and choose to omit that dreadful dot!

Besides, how else would we differentiate between “v” for “Version” and “v.” for “Verb?”
