Has HAPPENED. Yes, it is.
Only an independent clause can stand independently. A dependent clause is dependent on an independent clause.
An independent clause stands alone.
I think you can't have a subordinate independent clause. A subordinate clause is a clause which is dependant on another clause it can't stand alone as a sentence. An independent clause can stand alone as a sentence.
An independent clause is a sentence that can stand on its own.
A complex sentence is a sentence that contains an independent clause and at least one dependent clause. The independent clause can stand alone as a complete sentence, while the dependent clause relies on the independent clause to make sense.
A clause can not stand alone in a sentence, whereas an independent clause can stand alone in a sentence.
This question is somewhat ambiguously phrased, because independent and dependent clauses are mutually exclusive categories, and a clause that is introduced by a subordinate conjunction is not independent by definition. However, substituting a coordinating conjunction in a independent clause by a subordinate conjunction can convert an initially independent clause into a dependent clause.
It can be an independent clause or a dependent clause. It is an independent clause if does not have a word at the beginning like "but" or "because". If there is a word like this at the beginning of the clause, it is a dependent clause.
Yes, it is. That is why it is called "a dependent clause." It is dependent upon the independent clause.
An independent clause can also be called a simple sentence.
An independent clause can stand alone as a complete sentence; a dependent one cannot. An independent clause (or main clause, matrix clause) is a clause that can stand by itself, also known as a simple sentence. Independent clauses contain a subject and a predicate. Multiple independent clauses can be joined by using a semicolon or a comma plus a coordinating conjunction (for, and, nor, but, or, yet, so). The dog is running down the street = independent clause Because its master called it = dependent clause
An independent clause without a subordinate clause is NOT a sentence fragment. It is an independent clause, therefore it can stand "independently," or alone.However, if you decide to use a subordinating clause, you will need to add a dependent clause because subordinating conjunctions (because, after, although, et al) are used to create a complex sentences(an independent + dependent clause).
