Sentence Structures: The basic form of an English sentence is subject + verb + object. However, there are other sentence structures to make up larger sentences.
Clause: There are two types of clauses: an independent clause and a dependent one.
Independent clauses make up a subject + verb + predicate. This is why they are able to stand alone as a sentence.
"I'm currently living in the city of Chicago."
A dependent clause/subordinate clause is also made up of a subject + verb although they are not complete sentences, therefore are not able to stand alone.
These sentences can often begin with the words because, since, although, as they borrow the information from the previous sentence.
"I've visited Niagara Falls every year since I was young."
A complex sentence is made up of an independent clause and a dependent one.
"I am flying for a business trip, but you can hand me the papers after I arrive."
-----
Simple sentences are made up of only a single clause. Subject + verb + sometimes an object.
"I'm reading."
"I'm reading a book."
"My teacher gave us an exam."
-----
Compound sentences: These are made up of two independent clauses brought together by a comma as well as a coordinating conjunction such as: and, for, but, or ,yet, so
"Daniel is yelling and he is screaming at the protest."
