It and There

It: "It" is an introductory word. Where there is no subject in a sentence, we have to use 'it' as the introductory subject of that sentence. Now, let's know about the form of verb using after it. Here is a special note that 'it' always follows a singular verb. If we want to see the full combination of "it" and its "verb", the sentence structure will be like below:

• It + verb (singular) + extension....

There: "There" is also an introductory subject. It also performs as a subject where there is no apparent subject in a sentence. An important information to give about "there" is that, it can take a SINGULAR VERB as well as a PLURAL VERB. Actually it has no effect on the verb of the sentence it is used. Rather, the singularity and plurality of the verb this type of sentence depends on the noun and pronoun placed after the verb of the sentence. So, let's see the sentence structure of the sentence related to "there" -

• There + verb (singular) + noun (singular) + extension

• There + verb (plural) + noun (plural) + extension
