Prepositions are words normally placed before nouns or pronouns. Prepositions can also be
followed by verbs but the verb must be in the gerund form:
He is talking of emigrating.
They succeeded in escaping.
The student has two main problems with prepositions. He has to know (a) whether in any
construction a preposition is required or not, and (b) which preposition to use when one is
required.
Alternative position of prepositions
A. Prepositions normally precede nouns or pronouns. In questions beginning with a
preposition + whom/which/what/whose/where:
To whom were you talking? (formal)
Who were you talking to? (informal)
Omission of to and for before indirect objects
A1. A sentence such as I gave the book to Tom could also be expressed
I gave Tom the book, i.e. the indirect object can be placed first and the preposition to
omitted.
2 The construction with preposition is preferred:
(a) When the indirect object is a phrase or a clause:
We kept seats for everyone on our list/for everyone who had paid.
I had to show my pass to the man at the door.
Use and omission of to with verbs of communication
Verbs of command, request, invitation and advice, e.g. advise, ask, beg, command,
encourage, implore, invite, order, recommend, remind, request, tell, urge, warn, can be
followed directly by the person addressed (without to) + infinitive:
They advised him to wait.
The person addressed (without to) can be used after advise, remind, tell, warn with other
constructions also:
Time and date: at, on, by, before, in
A. at, on
at a time: at dawn at six at midnight at 4.30 .
at an age: at sixteen/at the age of sixteen
on a day/date: on Monday on 4 June on Christmas Day
B. by,
by a time/date/period = at that time or before/not later than that date. It often implies
'before that time/date':
The train starts at 6.10, so you had better be at the station by 6.00.
C. on time, in time, in good time
on time = at the time arranged, not before, not after:
The 8.15 train started on time. (It started at 8.15.)
D. at the beginning/end, in the beginning/end, at first/at last
at the beginning (of)/at the end (of) = literally at the beginning/end:
At the beginning of a book there is often a table of contents.
in the beginning/at first = in the early stages. It implies that later on there was a change:2
In the beginning/At first we used hand tools. Later we had machines.
Time: from, since, for, during
from is normally used with to or till/until:
Most people work from nine to five
from can also be used of place:
Where do you come from?
during is used with known periods of time, i.e. periods known by name, such as Christmas,
Easter or periods which have been already refilled:
during the Middle Ages during 1941
for (indicating purpose) may be used before known periods:
I went there/I hired a car/I rented a house for my holidays/for the summer.
Time: to, till/until, after, afterwards (adverb)
A. to and till/until
to can be used of time and place; till/until of time only.
We can use from ... to or from . . . till/until:
They worked from five to ten/from five till ten. (at five to ten would mean 'at 9:55'.)
B after and afterwards (adverb)
after (preposition) must be followed by a noun, pronoun or gerund:
Don't bathe immediately after a meal/after eating.
Don't have a meal and bathe immediately after it.
If we do not wish to use a noun/pronoun or gerund, we cannot use after, but must use
afterwards (= after that) or then:
Don't have a meal and bathe immediately afterwards.
They bathed and afterwards played games/played games afterwards
Travel and movement: from, to, at, in, by, on, into, onto, off, out, out of
A. We travel from our starting place to our destination:
They flew/drove/cycled/walked from Paris to Rome.
B. arrive at/in, get to, reach (without preposition)
We arrive in a town or country, at or in a village, at any other destination:
They arrived in Spain/in Madrid.
I arrived at the hotel/at the airport/at the bridge/at the crossroads.
Transport: by, on, get in/into/on/onto/off/out of
We can travel by car (but in the/my/Tom's car), by bus/train/plane/helicopter/hovercraft
etc. and by sea/air. We can also travel by a certain route, or by a certain place
C. Giving directions: at, into, to etc. (prepositions), along, on (prepositions and adverbs)
and till (conjunction):
