<h3>What is a sentence?</h3>
A sentence is actually known to be a group of words that have a subject and a predicate. Sentences are known to give complete thought. Independent clauses can be known to be sentences also as they give a complete thought.
Complex sentences are known to be sentences that have one independent clause and at least one dependent clause. We see here that the independent and dependent clauses are joined together by a conjunction and/or relative pronoun.
We see here that the above complex sentences have conjunctions like "because" and "although".
