Can you start a sentence with the word sentence?

The noun sentence (a text form, or a prison term) requires an adjective or article (a, the). But you can use it as an adjective itself, or as an imperative of the verb to sentence, to announce a judicial penalty.

Example : "Sentence construction is important in English grammar."

Example : "Sentence criminals to realistic prison terms and you will go a long way towards discouraging crime."
