I dont know about the last one (because we don't have any butter) Sorry!
Explanation:
Phrases are basically complete sentences while clauses need more explanation.
Like, if you said "The house has 4 windows" then I wouldn't need to ask for more information. But, if you just said "this train goes" then I'd be like...this train goes....where?
Clause: The house has four windows. The Train goes.
Phrase: Under the table. The cow in the shed. Because we don't have any butter.
Explanation:
Phrases are parts of a sentence that describe parts of a sentence. They don't have both a subject and a verb, so we can eliminate the house has four windows, and the train goes because these sentences both have a subject and a verb. In the sentence "the house has four windows", the subject is "house", and the verb is "has". In the sentence "the train goes", the subject is "train" and the verb is "goes" By eliminating these two sentences from being a phrase, we know that the rest of the parts are phrases.
