455: I Am Mar 7, 2016

“I am” is the shortest complete sentence in the English language, since it contains the shortest subject, and the shortest verb (as conjugated). Although "I'm" as a contraction would be shorter, forms of 'to be' don't get contracted at the end of English sentences, and would therefore not count. Some people argue that 'go' would be the shortest so long as it is considered to be imperative, but since it would be circumstantial, it would be a hard case to argue.
