Answer:
Clause
Step-by-step explanation:
A clause is a group of related words that at least contains a subject and a verb, and that may be independent or dependent. An independent clause, also called "sentence", expresses a complete thought and therefore, it can stand by itself. A dependent clause, on the other hand, cannot stand by itself because it does not have a full meaning on its own, and in a sentence, these clauses function adjectives, adverbs or nouns.
Here is an example of a sentence with a dependent clause (underlined) and an independent clause (not underlined):
After drinking that much liquor, I felt sick.
