3. HOW DO YOU RECOGNIZED THE
PREPOSITIONAL PHRASE?
At the minimum, 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 modifiersto describe it. These are the patterns for a
prepositional phrase:
PREPOSITION + NOUN, PRONOUN, GERUND, OR CLAUSE
PREPOSITION + MODIFIER(S) + NOUN, PRONOUN,
GERUND, OR CLAUSE

4. SOME EXAMPLES OF THE MOST BASIC
PREPOSITIONAL PHRASE
At home
At = preposition; home = noun.
In time
 In = preposition; time = noun.
From Richie
From = preposition; Richie = noun.
With me
With = preposition; me = pronoun.

8. SUBORDINATING CONJUNCTIONS
Subordinating conjunctions can have several types of
meanings:
TIME CAUSE
After As
As because
as long as not what
as soon as in as much as
Before since

9. • A few conjunctions can be used with more than
one meaning:
Since I’m here, I might as well help you.
(Cause)
Since I was ten years old, I’ve enjoyed soccer.
(Time)
As I told you before, soccer is fun. (Manner)
As I was going home, I saw my friend. (Time)

10. CONJUNTIVE ADVERBS
• We can also join two clauses with a conjunctive adverb.
These are words like however, therefore, or consequently.
These words are sometimes called transitions. For example:
Bob says he speaks ten languages; however, I
don’t believe him.
Bob says he speaks ten languages. However, I
don’t believe him.
Homework is important; therefore, I’ll do it
carefully.
Homework is important. Therefore, I’ll do it
carefully.
The bus was late; consequently, I was late for
class.

11. • Punctuation: There are three possibilities:
• Put a semicolon after the first clause and a comma after
the conjunctive adverb:
Bob says he’s a millionaire; however, I don’t
believe him.
 Or you can put a period after the first clause and a
comma after the conjunctive adverb:
Bob says he’s a millionaire. However, I don’t
believe him.
• Sometimes a conjunctive adverb comes in the middle of
a clause. Then it has commas before and after it.
Bob says he’s a millionaire. I, however, don’t
believe him.
