it doesn't contains other related words
These are called clauses.
You also can have a group of related words without a subject or predicate that's part of a bigger sentence--that would be a phrase. Prepositional phrases are common - to the window, to the wall, etc.
A phrase is a group of words that does not have a subject or predicate. A phrase may have a noun or a verb, but they do not function as a subject and predicate team like in a clause. Phrases modify, describe, and give information.
