It vs. This

Difference Between It and This

It and this are two words in the English language that are often confused in terms of their meaning. They are really two different words with different meanings. The word ‘it’ is the third person singular pronoun. On the other hand the word ‘this’ is a demonstrative pronoun. This is the main difference between the two words this and it.

The word ‘it’ is normally used to start sentences that pose an emphasis on a topic or idea as in the sentence ‘It is important to follow the rules and regulations.’ In this sentence the word ‘it’ is used in that place to emphasize on an idea. On the other hand the demonstrative pronoun is used to indicate something to someone as in the sentence ‘this is the book I mentioned in my talk’. In this sentence the word ‘this’ is used in a bid to demonstrate or present the book to someone by someone. It is also a significant difference between the two words ‘it’ and ‘this’.

Sometimes the word ‘it’ is used at the beginning of assertive sentences as in the sentence ‘It is raining heavily now’. You can see that this sentence begins with the word ‘it’. One of the primary uses of ‘it’ is its use as the third person singular form as the third-person pronouns ‘he’ and ‘she’. Look at the two sentences

1. It shines very well

2. It roars loudly.

In both sentences the word ‘it’ is used as the third person singular form. In the first sentence the pronoun ‘it’ refers to ‘the Sun’ and the second sentence in the third person singular form refers to a ‘lion’. Sometimes the demonstrative pronoun ‘this’ is used at the end of the sentence as in ‘I know this’.
