3. The Basics
At the very least, a prepositional phrase will begin with a preposition and end with a noun, pronoun, gerund, or clause- the "object" of the preposition.
The object of the preposition will often have one or more modifiers to describe it.

4. preposition + modifier(s) + noun, pronoun, gerund, or clause
Format
preposition + modifier(s) + noun, pronoun, gerund, or clause

5. Examples At home At = preposition; home = noun About what we need
About = preposition; what we need = noun clause.
In the weedy, overgrown garden
In = preposition; the, weedy, overgrown = modifiers; garden = noun.

6. What They Do
A prepositional phrase will function as an adjective or adverb. As an adjective, the prepositional phrase will answer the question Which one?
As an adverb, a prepositional phrase will answer questions such as How? When? or Where?

7. Unnecessary
Prepositional Phrases never contain the subject of the sentence. You should be able to take the phrase out of the sentence and it will still make logical sense.
