What is the shortest sentence?

The shortest sentence in English is "I am." It consists of two words, a subject pronoun "I" and a linking verb "am." Despite its brevity, it is a complete sentence and expresses a complete thought. The shortest sentence in other languages may vary. For example, in Spanish, the shortest sentence is "Yo soy," which means "I am" in English. In languages that use cases, one word sentences are also possible, such as in Latin where the sentence "Avis" means "Bird" and is a complete sentence.
