Class, may I have your attention please.
You may mean a noun of direct address, which is a noun for the person you are speaking to. It can be removed from a sentence without changing the meaning of the sentence, and is marked in the sentence by commas.Examples:Nancy, you have a meeting at ten.You have a meeting at ten, Nancy.Or, you may mean a noun as direct object, which is the noun that receives the action of the verb. The subject is the person or thing that the sentence is about; the verb tells what the subject does; the direct object is what receives the action expressed by the verb. A direct object can be a noun or a pronoun.Examples:Nancy, you have a meeting at ten.The class boarded the bus.The officer gave the driver directions. (gave directions to the driver)
Sometimes! Direct address can be anywhere in the sentence -beginning, middle, and end!Examples:Beginning: 'Jennifer, please do your homework.'Middle: 'After you clean your room, Caitlyn, we can eat some ice cream.'End: 'Which dog would you like, Joe?'By the way, the direct address is 90% of the time a name, except when someone says: Whatchamacallit, get me a burger!
A noun of direct address is a the noun for the person spoken to. For example:Mom, can John come over to do homework?It's okay John, mom said you can come over.Thank you sir. Or, Thank you ma'am.Hey mister, you forgot your change.Excuse me miss, you dropped your pen.
The function of a noun in direct address to get the attention of the one spoken to or to identify the person spoken to among two or more people. A noun in direct address is not a subject or an object of a sentence. A sentence should be a correct sentence when the noun of direct address is removed, for example:Greg, please pick up your things. OR Please pick up your things. (The subject of the sentence is the implied pronoun 'you'.)Listen for the telephone, kids. OR Listen for the telephone. (Again, the implied subject is the pronoun 'you'.)Please, Greta, accept my apologies. OR Please accept my apologies.Jack, you can pick up the kids and, Jane, you can stop at the store. (This is more polite than pointing at the person and saying "You can...")Note: A noun of direct address is always separated from the rest of the sentence by commas, whether it begins the sentence, is in the middle of the sentence, or ends the sentence.
Example sentence with a name in direct address (Mr. Campbell) and a possessive noun (Nancy's):Mr. Campbell, thank you for fixing Nancy's bicycle.
The noun in the sentence is "class," as it refers to a group of pupils.
"song" is the direct object in that sentence.
There are no nouns used as collective nouns in the sentence. A collective noun is a function of a noun, not a characteristic inherent in a noun The noun 'class' can be a collective noun for 'a class of students', but in this sentence, it is not functioning as a collective noun.
