Interjections are words that show excitement or emotion.
Nouns of direct address name the person or people being spoken to. (This is another
noun job. Now, you’ve learned that nouns can be subjects, objects of the preposition,
and nouns of direct address.)
Interjections and nouns of direct address are not grammatically related to the rest of the sentence. This means that they don’t describe, modify, or affect anything else in the sentence.
When diagrammed, they sit on a line floating above the sentence.
