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.
Quick Quiz: In the following sentences, why is “to” followed by a verb? That should be impossible, according to the above rule:
I would like to go now.
She used to smoke.
Here are some examples:
Subject + verb preposition “noun”
