2. Phrases – a group of words that lacks a subject, a verb, or both.

3. Prepositional
Preposition – a word used to show the relationship of a noun or pronoun to some other word in the sentence. Common prepositions: about, above, across, around, at, before, between, by, concerning, during, except, for, from, in, into, of, over, since, through, to, toward, under, until, up, upon, with, within.
Def. – A prepositional phrase is a group of words beginning with a preposition and usually ending with a noun or pronoun.
Examples – at the lake; inside the house; under the sea; along the path
Rule of thumb – Prepositional phrases do not stand by themselves; they are parts of a sentence and are used as modifiers (a modifier is a word or phrase that describes or makes more definite), sometimes as adjectives and at other times as adverbs. [An adjective phrase is a prepositional phrase that modifies a noun or a pronoun; ex. That tall building with the red tower is our new library.] [An adverb phrase is a prepositional phrase that modifies a verb, an adjective, or another adverb; ex. Louisa May Alcott wrote with great care.]

5. Participial phrases
Participle – a word that is formed from a verb and used as an adjective; ex. The talking students were asked to be quiet. The cheering fans waited for their team to arrive.
Def. – A participial phrase is a phrase containing a participle and any complements (complement - one or more words in the predicate that complete the meaning of the subject and verb) or modifiers it may have. A predicate is the part of the sentence that says something about the subject [i.e. the verb and those words that follow; ex. John (subject) walks by the road (predicate).]
Examples – Nodding his head, the student agreed with the teacher. Holding her breath, the cheerleader waited for the results. Disturbed by his letter, she called him on the phone.

Appositive – a noun or pronoun that follows another noun or pronoun to identify or explain it. Ex. Her sister Nancy was a year older. My favorite dog Sherman ran away from home.
Def. – An appositive phrase is made up of an appositive and its modifiers.
Examples – We drove through Tallahassee, the capital of Florida. George Washington, the first president of America, was a great military leader.
