A declarative sentence is a statement. A compound-complex sentence has at least two independent clauses joined with a coordinating conjunction and at least one dependent clause. An appositive is a noun that serves to describe another noun. A linking verb is a verb that connects the subject noun to a predicate adjective (describing the noun) or predicate noun (renaming the noun). A pronoun is a word that takes the place of a noun, to avoid repeating it (“it” is a pronoun!)
Consider the following declarative sentence.
Charles Dickens is my favorite author.
It is declarative because it gives information. It contains a linking verb (is) connecting the subject noun (Charles Dickens) to the predicate noun that renames it (author). This sentence also includes a possessive pronoun (my).
However, this is a simple sentence. It is one independent clause. I need to add at least one more independent clause and a dependent subordinate clause.
Charles Dickens is my favorite author, and I have read all of his books.
I added a coordinating conjunction (and) set off by the required comma and a second independent clause. Right now the sentence is a compound sentence.
Now we can add the word “smugly,” which means arrogantly or full of oneself.
Charles Dickens is my favorite author, and I have smugly read all of his books.
Now all we need is a dependent subordinate clause.
Charles Dickens is my favorite author, and I have smugly read all of his books, because I am so smart.
The dependent subordinate clause is because I am so smart and is separated by a comma as all dependent clauses are. Note that you actually have three pronouns altogether (my, I, his).
The only thing missing is the appositive.
Writer Charles Dickens is my favorite, and I have smugly read all of his books, because I am so smart.
I have replaced the word “author” with “writer” and made “Charles Dickens” the appositive describing “writer.”
And we're done!
