Prepositions

Prepositions indicate relationships between words and ideas. Most prepositions deal with location and are easy to learn.

* These can also be used as conjunctions.

Some prepositions, however, have more than one meaning and can be very confusing.

in	on	at
to	from	for	of

Generally, in, on and at indicate location.
