Many use the words of and off interchangeably, due to lack of knowledge about their meaning and usage. ‘Of‘ is a preposition which is used in sentences to show belongingness or possessiveness. It is commonly contrasted with the word ‘off‘ which is used when we mean ‘away from a person, object or place’. Let’s take a look at the examples given below to understand their difference:
- The game had to be called off because of incessant rains.

In the first sentence, we are using a phrasal verb called off to mean cancel, whereas of is used to give a reason. In the next sentence, take off implies remove, while of is used to show the source or derivation.
