I have heard that two letter verbs are the shortest verbs in English. Is this totally true? Are any of the letters official recognized as verbs?
Forms: Pa. tense x-ed, x'd.
- trans. To supply with x's in place of types that are wanting. rare—1.
1849 E. A. Poe X-ing a Paragrab in Wks. (1856) IV. 265 ‘I shell have to x this ere paragrab,’ said he to himself, as he read it over... So x it he did, unflinchingly, and to press it went x-ed.
I'm sure there are others.
"Go" isn't any shorter than "do" or "be", so you heard a partial truth. The whole truth is that "Go, do, and be are the shortest verbs in English".
None of the vowels is officially recognized as a verb: an indefinite article -- a; a personal pronoun --I; an interjection -- O (variant of Oh); a texting abbreviation for why -- y; and a texting abbreviation for you --u.
None of the single vowel combinations are verbs - 'A' is an article, 'O' is an exclamation, and 'I' is a pronoun. Depending on how far you want to stretch the definition of "officially recognized" 'U' is a common shorthands for "you", and are hence is a noun and noun/adverb/exclamation respectively. None are verbs, and the others are not standard English words.
The shortest verb, technically, is 'X':
Mark or make a sign with an X.
Although it is reasonably uncommon.
There are, however, several two-letter verbs in common usage - such as "be", "do" and "go".
