What is passive voice of it rains yesterday?

Answer 1

In linguistics, an impersonal verb is one that has no determinate subject. For example, in the sentence "It rains", rain is an impersonal verb and the pronoun it does not refer to anything. In many languages the verb takes a third person singular inflection and often appears with an expletive subject. In the active voice, impersonal verbs can be used to express operation of nature, mental distress, and acts with no reference to the do-er.[1] Impersonal verbs are also called weather verbs because they frequently appear in the context of weather description.[2] ValencyImpersonal verbs appear only as infinitives or with third-person inflection(s).[3] In the third person, the subject is either implied or a dummy referring to people in general. The term "impersonal" simply means that the verb does not change according to grammatical person. In terms of valency, impersonal verbs are avalent, meaning that they altogether lack semantic arguments. In the sentence It rains, the pronoun it is a dummy subject; it is merely a syntactic placeholder - it has no concrete referent. In many other languages, there would be no subject at all. In Spanish, for example, It is raining could be expressed as simply llueve. Indo-EuropeanIn English

The following sentences illustrate impersonal verbs:(1) It rains.(2) It is cold.(3) It is growing dark.(4) It seems that there is no end to this.(5) It is unclear why he cut the rope.

The expletive pronoun it in these sentences does not denote a clear entity, yet the meaning is clear. In other words, the pronoun it has no clear antecedent. [6]. English is so strict about requiring a subject that it supplies them for verbs that do not really require them. In sentences (4) and (5), it is in the subject position, while the real subject has been moved to the end of the sentence.

A simple test can be done to see if the sentence contains an impersonal verb. One checks to see if a given subject pronoun takes an antecedent in the previous clause or sentence, e.g.Bukit Timah is 163.63 metres tall. It is the highest point in Singapore.Bukit Timah is 163.63 metres tall. It rains frequently there.

The two examples may seem similar, but only the pronoun it in the first example links with the previous subject. The pronoun it in the second example, on the other hand, has no referent. The hill (Bukit Timah) does not rain, it rains. This demonstrates that rain is an impersonal verb.[7]
