No. This is a sentence with only one word: "Go."
One possible sentence is: "What is a sentence that uses the word particular?"
A "sentence" in grammar is a group of words that expresses a complete thought. Most sentences consist of at least a subject (noun form) and a predicate (verb form). The word "sentence" can also mean the punishment given for a criminal offense. Specifically, a sentence may include incarceration, or fines, or both, and may contain a period of supervised probation.
A sentence can have just one word, so "No." can be a sentence.
Other than strengthen, the word could be reinforce, fortify, boost, or toughen.
