Who (pronoun)


The pronoun who, in English, is an interrogative pronoun and a relative pronoun, used chiefly to refer to humans.
Its derived forms include whom, an objective form whose use is now generally confined to formal English; the possessive form whose; and the indefinite form whoever ever, and whos.

Etymology

The word who derives from the Old English hwā. The spelling who does not correspond to the word's pronunciation ; it is the spelling that represents the expected outcome of hwā, while the pronunciation represents a divergent outcome – for details see Pronunciation of English ⟨wh⟩. The word is cognate with Latin quis and Greek ποιός.
The forms whom and whose derive respectively from the Old English dative and genitive forms of hwā, namely hwām and hwæs.

Uses

As interrogative pronoun

Who and its derived forms can be used as interrogative pronouns, to form questions:
The same forms are used to make indirect questions:
The corresponding form when referring to non-humans is what. Another similar interrogative is which – this can refer to either humans or non-humans, normally implying selection from a particular set, as either interrogative pronoun or interrogative determiner . What can also be used as a determiner, but who cannot.
Which, who, and what as interrogatives can be either singular or plural.. But who and what often take a singular verb regardless of any supposed number; the questions Who wants some cake? and What's in the bag? do not presuppose anything about number in possible responses: I want some cake, or All of us want some; and A rabbit is in the bag, or Five coins and a bus ticket.

As relative pronoun

The other chief use of who and its derivatives are in the formation of relative clauses:
The corresponding form for non-humans is which, although whose can be used as a possessive in relative clauses even when referring to non-humans: I will have to fix the car whose engine I ruined.
In restrictive relative clauses, when not preceded by a preposition, both who and which can be replaced by that, or by zero.
In relative clauses, who takes the number of its antecedent. Who also takes the person of its antecedent:
Who and whom can also be used to form free relative clauses. The emphatic forms are often used for this purpose: informal: I'll take whoever you choose; formal: I'll take whomever/whomsoever you choose.. This corresponds to the use of what when referring to non-humans. and whom
The emphatic forms can also be used to make adverbial clauses, as in Whoever you choose, I'll be satisfied.

Usage of ''whom''

Tendency to replace ''whom'' with ''who''

According to traditional prescriptive grammar, who is the subjective form only, while whom is the corresponding objective form. However it has long been common, particularly in informal English, for the uninflected form who to be used in both cases, thus replacing whom in the contexts where the latter was traditionally used.
In 1975, S. Potter noted, in Changing English, that "nearly half a century ago Edward Sapir predicted the demise of whom, showing at great length that it was doomed because it was 'psychologically isolated' from the objective pronouns me, us, him, her, them on the one hand, and the invariables which, what, that and where, when, how, why on the other." By 1978 the whowhom distinction was identified as having "slipped so badly that almost totally uninformative". According to the OED, whom is "no longer current in natural colloquial speech". Lasnik and Sobin argue that surviving occurrences of whom are not part of ordinary English grammar, but the result of extra-grammatical rules for producing "prestige" forms.
According to Mair, the decline of whom has been hastened by the fact that it is one of relatively few synthetic remnants in the principally analytical grammar of Modern English. It has also been claimed that the decline of whom is more advanced in the interrogative case than in the relative case, this possibly being related to the degree of complexity of the syntax.
However, some prescriptivists continue to defend whom as the only "correct" form in functions other than the subject. Mair notes that: "whom is moribund as an element of the core grammar of English, but is very much alive as a style marker whose correct use is acquired in the educational system . is highly restricted, but rather than disappear entirely, the form is likely to remain in use for some time to come because of its overt prestige in writing."
Whom is also sometimes used by way of hypercorrection, in places where it would not even be considered correct according to traditional rules, as in Whom do you think you are? For more examples see the section below.
Retention of the whowhom distinction often co-occurs with another stylistic marker of formal or "prestige" Englishavoidance of the stranded preposition. This means that whom can frequently be found following a preposition, in cases where the usual informal equivalent would use who and place the preposition later in the sentence. For example:
In relative clauses, movement of the preposition further allows who to be replaced by that or the empty string:
He is someone that I owe a great deal to or
He is someone I owe a great deal to...

Usage of ''who'' and ''whom''

In the types of English in which whom is used, the general grammatical rule is that who is the subjective form, analogous to the personal pronouns I, he, she, we, they, etc., while whom is the objective form, analogous to me, him, her, us, them, etc. Thus who is used as a verb subject, while whom is used as an indirect or direct object of a verb or as the object of a preposition.
Examples:
Notice that in a relative clause, the form depends on the role of the pronoun in the relative clause, not that of its antecedent in the main clause. For example, I saw the man who ate the pienot whom, since who is the subject of ate ; it makes no difference that its antecedent man is the object of saw.
In the position of predicative expression, i.e. as the complement of forms of the copula be, the form who is used, and considered correct, rather than whom.
In the examples that follow, notice how, when the verb is a form of be, the question "Who is the captain of the team?" or the noun clause "who the captain of the team is" is the same regardless of whether the original placement of the unknown person was before or after be :
A problem sometimes arises in constructions like this:
Use of who here is normal, and to replace it with whom would be grammatically incorrect, since the pronoun is the subject of was, not the object of say. Nevertheless whom is quite commonly encountered, and even defended, in sentences of this type. It may arise from confusion with a form like:
In this case, whom is used correctly according to the traditional rules, since it is now the object of the verb believe.
The use of whom in sentences of the first type referred to as subject whomcan therefore be regarded as a hypercorrection, resulting from awareness of a perceived need to correct who to whom in sentences of the second type. Examples of this apparently ungrammatical usage can be found throughout the history of English. The OED traces it back to the 15thcentury, while Jespersen cites even earlier examples from Chaucer. More examples are given below:
Doubts can also arise in the case of free relative clauses, formed with who, whoever or whosoever. Modern guides to English usage say that the relative pronoun should take the case appropriate to the relative clause, not the function performed by that clause within an external clause. For example, it is correct to write I'll talk to whoever will listen, since whoever is the subject of will listen. On the other hand, Whomever you choose will suit me is correct, since whomever is now the object of choose.
Similarly:
In sentences of this type, however, as with the "subject whom" examples above, use of whom is sometimes found in places where it would not be expected grammatically, due to the relative complexity of the syntax. In fact in Middle English it was standard for the form of the pronoun to depend on the function in the external clause; the modern rule came about through re-analysis of the pronoun as primarily an element of the internal clause.

Usage of ''whose''

Whose is the genitive case of who: The boy whose name I don't remember came from Japan.
Many people feel that whose should only used for persons, and when referring to inanimate things, "of which" should be used, or the sentence should be rephrased.
The movie the title of which I don't remember was very good or: I saw a very good movie, but I don't remember its title.
However, whose has also been used to refer to inanimate things since the 15th century.
See inanimate whose.

Usage notes

Who also forms in relative clause, for a specify information about a person or animals, if replaced by he or she
