"In", "on", "of", "off", "around", "with" and "under" are all prepositions; there are lots of others.
A preposition usually precedes a noun to show the noun's relationship to something else in the sentence. (e.g. In the sentence "It is a shelf
for ornaments.", the preposition "for" shows the relationship between "ornaments" and "shelf".

Some verbs include prepositions which modify their meanings (e.g. to pass up, to pass out, to pass over).
However, when the preposition does not add anything, you should omit it to make the sentence more succinct.

This is more succinct than the version below.

The prepositions "up to" do not add anything to this sentence.
Where possible, a sentence should not end in a preposition. In order to avoid ending in a preposition, it is often necessary to re-word your sentence.
It is behaviour I will not tolerate.
This has the same meaning as the sentence below and does not end in a preposition.
It is behaviour I will not put up with.
This sentence ends in the preposition "with". (In fact, it ends in two prepositions: "up" and "with".)
A sentence should not end in a preposition. However, if all alternative solutions sound too contrived, leave the preposition at the end.
This is an event we cannot account for.
Ending a sentence in a preposition does not constitute a grammatical howler; and, quite often, re-wording sounds too contrived.
This is an event for which we cannot account.
Although grammatically sound, this version sounds too contrived.
The word "who" never follows a preposition. It is always "whom". This is because prepositions govern the objective case.
Anne went to the meeting with whom?
After a preposition, like "with", you must use "whom". Anne went to the meeting with who?
"Who" is never the object of a preposition (i.e. never follows a preposition).
