Off vs. Of
This time, let's focus on some grammatically confusing words. Do you wanna expand your knowledge of the English language? Join me, then.
What Is Their Main Difference?
Both can be prepositions and have nearly identical dictations. 'Off', however, is the contrasting word for 'on' and indicates separating something from the other. It can be an adverb, too. 'Of' refers to something that is part of another thing. We can also use 'of' to indicate a specific point in time or space. Additionally, we can make a noun phrase out of a verb phrase using 'of'.
Diffrernces
As mentioned above, 'off' shows disconnecting something/someone from another thing/person. It can function as both a preposition and an adverb. Look at the examples below:
Let me take
The airplane took
'Of', on the other hand, can have several meanings. We can use it to make a noun phrase out of a verb phrase. When we want to refer to something that is a part of another thing, we mainly use 'of'. Also, we can use 'of' to refer to a particular point in time and space. Another use of 'of' is to refer something that contains another thing in itself. Look at the examples below:
Let me get you a glass
Here, 'of' indicates something that contains another thing.
A part
Here, it is referring to something that is part of another thing.
At the time
In this example, it is referring to a particular period of time.
Similarities
Their only similarity is that they can both be prepositions. Look:
Clean
We will all be celebrating the victory on the 5th
Are They Interchangeable?
Although they can both be prepositions, they can never be used interchangeably. Compare:
✓ The students ran
X The students ran
As you can see, this one is grammatically and semantically incorrect.
