How do you tell a sentence is positive in english grammar.

A positive sentence is a sentence that tells you how something is, as opposed to how it is not. These sentences can be identified in two different ways. First, we can identify them by their meaning. If the meaning is affirmative (it does not deny anything), then the sentence is positive. These sentences can also be identified by their lack of negative words, such as no, never, not, no one, nobody, etc.

therefore, the fact that the grandfather is wearing a bolo tie refers to his heritage as native american.
