Causes of Breast Bone Pain. 1  Heartburn or reflux is the most common cause of a burning pain along and under the breast bone as a result of esophagitis. Gastroesophageal reflux (GERD) may also result in episodes of severe sharp pains in the chest and is often mistaken for a myocardial infarction (heart attack) during these episodes.
A complex sentence contains an independent clause and at least one dependent clause. A sentence with two or more independent clauses plus (one or more) dependent clauses is referred to as a compound-complex sentence. (Every clause contains a subject and predicate).
A clause is a statement or a question that generally consists of a subject and a verb phrase and constitutes a complete thought. Sentences can consist of a single clause, but they often include two: a main, or independent, clause and a subordinate, or dependent, clause. A main clause can form a complete sentence. (The preceding statement is both a clause and a sentence.) A subordinate clause, by contrast, depends on a main clause to provide the primary proposition of the sentence, which is why itâs also called a dependent clause.
