A phrase and a clause are two different topics you would have learned in the English Language, even at the secondary stage of schooling. Foremost, the phrase is known to be a short and simple expression, but it is meaningful. It can be defined as a word or group of words that functions as a unit in the syntax of a sentence, and it usually consists of a central word or a head and elaborating words.
The phrase can be simplified as a fragment of a sentence that contains a noun or a verb. You should kindly note that a phrase does not contain both noun and verb, but just one of the two. In contrast, the clause simply refers also to a fragment of a sentence that actually contains both noun and verb.
There majorly two kinds of clauses, which are the dependent clause and the independent clause. The independent clause can stand on their own to make a meaningful statement, while the dependent clause needs to be attached to another clause to make a meaningful sentence.
