Preposiciones

English 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 bya 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 befollowed 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"
The food is on the table.
She lives in Japan.
Tara is looking for you.
The letter is under your blue book.
Pascal is used to English people.
She isn't used to working.
I ate before coming.The name "preposition" (pre + position) means "place before". Prepositions usually come *before* another word, usually a noun or noun phrase:
• Noun (I will meet you IN *London*.)
• Pronoun (Giveit TO *her*.)
• Noun phrase (I'm tired OF *all this work*.)
• Gerund (verb in -ing form) (It crashed ON *landing*.)
If a preposition does not come before another word, it is still closelyassociated with another word:
• *Who* did you talk TO?
• TO *whom* did you talk?
• I talked TO *Jane*.
Notice that many prepositions can also be adverbs:
• He walked DOWN the hill. (preposition)
•Please sit DOWN. (adverb)
A few prepositions can also be conjunctions:
• Everyone came BUT Tara. (preposition)
• I asked her BUT she didn't answer. (conjunction)
