- Nouns & Pronouns
These have many jobs in a sentence. They can be the subject, direct object, indirect object, or the object of the preposition.

They can also be predicate nouns.
Nouns can also be objective complements. An objective complement is a noun or an adjective that completes the direct object.

- Miscellaneous: Appositives
I wasn't sure where to put these, so here they are on the parts of speech page!
Appositives are nouns that rename the subject.

- Miscellaneous: Negatives
Here is another category that landed on the parts of speech page because I don't know where else to put them!
Negatives like not or n't are adverbs. That means that they go on a slanted line under the verb.
If you have a contraction like isn't, you put the verb is on the verb line and the adverb n't on the adverb line.
You can either write n't as n't or not, since n't is a contraction for not.
