Answer:
Phrase, Idiom or Sentence
Explanation:
A sequence of words that form a meaning can be a phrase, idiom or a sentence.
A phrase is a group of words that form a meaning. It can be a combination of a preposition and a noun, or an adjective and a noun. <em>Prepositional phrase</em> is for example "in the air", and an <em>adjectival phrase</em> is "a beautiful girl".
An idiom is a phrase that when formed, changes the meaning of the words in a phrase. For example,<em> "It's raining cats and dogs".</em> This sentence doesn't mean that literally cats and dogs fall from the sky, but it has a different meaning, which is <em>"It is heavily raining." </em>
A sentence is a group of words that must consist of at least subject and a verb, which can be followed by other words or phrases. For example, a phrase is <em>"a beautiful girl"</em> - it cannot be a sentence because it doesn't have a verb. If we say <em>"A beautiful girl is here."</em> - we make a sentence, because now it has a <em>subject (A beautiful girl), a verb (is) and a preposition of place (here). </em>
