344: Impersonal Pronouns Nov 17, 2015
Pronouns in general are used to take the place of one or more previously identified nouns. There are occasions when pronouns with no conceivable antecedents will exist. The verb in these types of sentences is called 'impersonal'. Much to the same effect that 'there' is used factually and existentially, such as in the sentence, 'there is suffering", pronouns such as 'it' and 'they' can express an action or circumstance that has no subject, such as, "it is raining" or "it's peculiar that cats don't have collar bones".
