what are the differences between those 3 sentences?
Quote = use someone else's exact words
Phrase = group of words that go together
Sentence = grammatically complete unit starting with a capital letter, containing a main verb and ending in with termal punctuation like a full-stop (period). By terminal punctuation, I mean wyas of ending things- commas, semi-colons and colons don't mark the end of the whole sentence, but fullstops, question marks and, sometime, exclamation marks do.
