Everything you need to know to use OF in English correctly:

This time we want to tell you about the correct use of OF in English. Well, we recognize that it is a proposition that, although we usually use it. It is difficult to use OF in English correctly due to the confusion with the apostrophe “S”.

As you can see, on many occasions we can use OF. However, it is also true that sometimes using OF can sound a bit strange. 

That is why in this post we will answer the question: how to use OF correctly in English? and many other things that you have to know about the OF. If you don’t know the use of “OFF” then check out.

All right then, what are we waiting for?

What Is The Correct use of OF in English?

It is very likely that you have noticed that an OF with people’s titles, for example:

  • The King of Australia
  • The Queen of England

This is due to the importance of the title given, which is why OF is said in the middle to make it easier for each word to be pronounced clearly.

Do not say:

  • Australia’s King
  • England’s President

So, as a way of enhancing or highlighting the title or name of a person or place, the use of OF in English should be used instead of OF’s. However, there are also a variety of situations in which both are possible, for example:

  • San Francisco’s streets: The streets of San Francisco. (normal effect)
  • The Streets of San Francisco

(So titled the American television series that way to make it sound more exciting or great)

  • The Aslam’s book: it is a normal effect
  • The book of the Aslam: it sounds more shocking and great

Which way is better?

The above examples show that both context and situation – as is often the case – are extremely important in determining the use of OF in English. 

Aspects such as the importance of highlighting a name or title come into consideration. If it is not so relevant, uses.

As an example, let’s imagine a terrible unforeseen event occurs where there was a car accident, where people could say:

  • In my opinion, the driver’s negligence caused this dangerous accident: I believe the driver’s negligence caused this dangerous accident.

But now, let’s imagine that the driver has been brought to trial where his guilt is proven. To emphasize the sentence, the judge might say something like:

We will evince that the negligence of the driver caused the accident: We will demonstrate that the driver’s negligence caused the accident.

Understanding the differentiation between OF and ‘S’ requires reading and listening to how people or objects are referred to in English. Since, it is very possible that although something seems important to you, using of is not the most convenient.

Use of OF with determinative adjectives in English

There are two types of determinative adjectives (determiners):

  1. a) Those that help us identify things
  2. b) Others, which are mostly quantifiers, which help us determine the amount

Use OF with “both” in English correctly

  • Both OF our cars broke Our two cars broke down.
  • Both OF my brothers like Van Gogh – My two brothers like Van Gogh.
  • Both OF these drawers are empty – These two drawers are empty.

When can’t you use OF?

When it comes to personal objects or possessions, as well as parts of the body, we must refrain from using OF; this, even though they may seem important to us. So, “S” is used with this type of case. For example:

  • My Sister’s pen

No matter how valuable this watch may be to your brother, it will not be used of:

  • The pen of my sister

When are both used?

We must also recognize that there are a variety of circumstances in which we can resort to both structures. That is, both to the apostrophe “S” and to the use of’ of ‘in English. 

But, more than a rule, let us remember that “custom” plays an important role in its use as well. Due to the need to simplify the language, it is common for the “Saxon genitive” to be used more.

Let’s look at some examples:

  • The Queen’s statement: The statement of the queen
  • Mar’s atmosphere: The atmosphere of the mars
  • American’s history: The history of America
  • The school’s guidelines: The guidelines of the school

We have reached the end of this post. Hopefully, you understand a little more how to use OF correctly in English, as it is a preposition that often leads to confusion. 

Always keep in mind that both importance and naturalness are important to know when to use it.
