 A preposition is a word that connects one thing with another and shows how they are related. It is usually followed by a noun or a pronoun.

Prepositions can tell us about place or position:

The book fell off the table.
My shoes are under the bed.
I jumped into the pool.
I keep my keys in my handbag.
Sarah is at school.

They can also tell us about time:

For giving advice or expressing a conclusion 'should' and 'ought to' are interchangeable. They are used to express the same ideas.

The structure used to + infinitive is used to refer to a past routine or situation which no longer exists at the present time.

Inversion describes a sentence where the verb is placed before the subject. It is sometimes difficult to remember when inversion is used and it is important to also understand when it should not be used.

In every day English the most common use of inversion is in questions:

Does he like pasta? Can you speak Chinese?

And after 'so', 'neither' or 'nor':

So do I. Neither does she. Nor do I.

Be/Get used to

Average: 3.9 (18 votes)

The structures be used to and get used to are used to talk about being accustomed to something or getting accustomed to something. Get used to talks about the process. Be used to talks about the result.

When Giovanni moved to London from Italy it took him long to get used to the cold. For Ivan, who moved from Moscow to London, the cold was not a problem because he was used to it.

Subject-Verb Agreement

Average: 5 (11 votes)

When we write a sentence we need to make sure that the subject and the verb agree. This means:

If the subject is a singular noun or the pronouns he, she, it, it must take a singular verb.

He enjoys playing tennis.
The dog barks loudly.
The cat is eating its food.
Carol has bought a new dress.
Does she know the answer?

Of and From

Average: 3.8 (26 votes)

Many learners of English find it difficult to know when to use 'of' and when to use 'from' in English. This is probably because in their languages the same preposition is used for both.


'of' for possession

We use 's for living things, groups and institutions. For inanimate objects we use 'of'
's – Tom's cat.
Of – The title of the film – the name of the game.

There, Their and They’re

Average: 4.1 (16 votes)

It is common for learners of English to confuse 'there', 'their' and 'they're' especially since they all have the same sound when being pronounced. Here is an explanation of each one:


'There' has the opposite meaning of 'here'. It is used to mean 'not a place close to' the speaker.
Have you seen mu glasses?
Yes, over 'there', on the table.

I'm driving to work. I'll call you when I get 'there'.
