Prevalence[edit] Waking up in the middle of the night, or nocturnal awakening, is the most frequently reported insomnia symptom, with approximately 35% of Americans over 18 reporting waking up three or more times per week.
Definitions. A clause is a group of words containing a subject and verb. An independent clause is a simple sentence. It can stand on its own. Examples: She is hungry. I am feeling well today. A dependent clause cannot stand on its own. It needs an independent clause to complete a sentence. Dependent clauses often begin with such words as although, since, if, when, and because.
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.
