Preposition

PREPOSITIONS


§  preposition is a word which precedes a noun (or a pronoun) to show the noun's (or the pronoun's) relationship to another word in the sentence.
§  The word preposition comes from the idea of being positioned before. It is not true to say that a preposition always precedes a noun or a pronoun, but it does most of the time.

The following are all prepositions:
above, about, across, against, along, among, around, at, before, behind, below, beneath, beside, between, beyond, by, down, during, except, for, from, in, inside, into, like, near, of, off, on, since, to, toward, through, under, until, up, upon, with and within.
Examples:
§  The book is on the table.
§  The book is leaning against the table.
§  The book is beside the table.
§  She held the book over the table.
§  She read the book during class.
Preposition Rule
There is one very simple rule about prepositions. And, unlike most rules, this rule has no exceptions.
Rule: A preposition is followed by a "noun". It is never followed by a verb.
By "noun" we include:
§  noun (dog, money, love)
§  proper noun (name) (Bangkok, Mary)
§  pronoun (you, him, us)
§  noun group (my first job)
§  gerund (swimming)
A preposition cannot be followed by a verb. If we want to follow a preposition by a verb, we must use the "-ing" form which is really a gerund or verb in noun form.
Here are some examples:
subject + verb
preposition
"noun"
note
The food is
on
the table.
noun
She lives
in
Japan.
proper noun
Tara is looking
for
you.
pronoun
The letter is
under
your blue book.
noun group
Pascal is used
to
English people.
She isn't used
to
working.
gerund
I ate
before
coming.
