Usage note

Traditionally, the masculine singular pronouns he1 , his, and him have been used generically to refer to indefinite pronouns like anyone, everyone, and someone ( Everyone who agrees should raise his right hand ) and to singular nouns that can be applied to either gender ( painter, parent, person, teacher, writer, etc.): Every writer knows that his first book is not likely to be a bestseller. This generic use is often criticized as sexist, although many speakers and writers continue the practice.
Those who object to the generic use of he have developed various ways of avoiding it. One is to use he/she or she/he (or he or she or she or he ) or the appropriate case forms of these pairs: Everyone who agrees should raise his or her (or her or his or his/her or her/his ) right hand. Forms blending the feminine and masculine pronouns, as s/he, have not been widely adopted, probably because of confusion over how to say them.
Another solution is to change the antecedent pronoun or noun from singular to plural so that the plural pronouns they, their, and them can be used: All who agree should raise their right hands. All writers know that their first books are not likely to be bestsellers. See also they.

Usage alert

Long before the use of generic he was condemned as sexist, the pronouns they, their, and them were used in educated speech and in all but the most formal writing to refer to singular indefinite pronouns or singular nouns of general personal reference (which are often not felt to be exclusively singular): If anyone calls, tell them I'll be back soon. A parent should read to their child. Such use is not a recent development, nor is it a mark of ignorance. Shakespeare, Swift, Shelley, Scott, and Dickens, as well as many other English and American writers, have used they and its related case forms to refer to singular antecedents. Already widespread in the language (though still rejected as ungrammatical by some), this use of they, their, and them is increasing in all but the most conservatively edited American English. This increased use is at least partly impelled by the desire to avoid generic he or the awkward he/she and he or she when the antecedent’s gender is not known or when the referent is of mixed gender: The victim had money and jewelry taken from them. It’s hard to move an aging mother or father from their long-term home.
However, while use of they and its forms after singular indefinite pronouns or singular nouns of general personal reference or indefinite gender is common and generally acceptable, their use to refer to a single clearly specified, known, or named person is uncommon and likely to be noticed and criticized, as in this example: My hair stylist had their car stolen. Even so, use of they, their, and them is increasingly found in contexts where the antecedent is a gender-nonconforming individual or one who does not identify as male or female: Tyler indicated their preferences on their application.
And although they may be used as a singular pronoun, they still takes a plural verb, analogous to the use of "you are" to refer to one person: The student brought in a note to show why they were absent. See also he1.

Word Origin and History for their

c.1200, from Old Norse þierra, genitive of þeir "they" (see they). Replaced Old English hiera. Use with singular objects, scorned by grammarians, is attested from c.1300. Theirs (c.1300) is a double possessive. Alternative form theirn (1836) is attested in Midlands and southern dialect in U.K. and the Ozarks region of the U.S.

they

pron.

c.1200, from Old Norse þeir, originally masculine plural demonstrative pronoun, from Proto-Germanic *thai, nominative plural pronoun, from PIE *to- (see that). Gradually replaced Old English hi, hie, plurals of he, heo, hit (see he, she, it) by c.1400. Colloquial use for "anonymous people in authority" is attested from 1886.

it

pron.

Old English hit, neuter nominative and accusative of third person singular pronoun, from Proto-Germanic demonstrative base *khi- (cf. Old Frisian hit, Dutch het, Gothic hita "it"), from PIE *ko- "this" (see he). Used in place of any neuter noun, hence, as gender faded in Middle English, it took on the meaning "thing or animal spoken about before."

The h- was lost due to being in an unemphasized position, as in modern speech the h- in "give it to him," "ask her," "is only heard in the careful speech of the partially educated" [Weekley]. It "the sex act" is from 1610s; meaning "sex appeal (especially in a woman)" first attested 1904 in works of Rudyard Kipling, popularized 1927 as title of a book by Elinor Glyn, and by application of It Girl to silent-film star Clara Bow (1905-1965). In children's games, meaning "the one who must tag the others" is attested from 1842.

she

pron.

mid-12c., probably evolving from Old English seo, sio (accusative sie), fem. of demonstrative pronoun se "the," from PIE root *so- "this, that" (see the). The Old English word for "she" was heo, hio, however by 13c. the pronunciation of this had converged by phonetic evolution with he "he," which apparently led to the fem. demonstrative pronoun being used in place of the pronoun (cf. similar development in Dutch zij, German sie, Greek he, etc.). The original h- survives in her. A relic of the Old English pronoun is in Manchester-area dialectal oo "she." As a noun meaning "a female," she is attested from 1530s.

he

pron.

Old English he (see paradigm of Old English third person pronoun below), from Proto-Germanic *hi- (cf. Old Saxon, Old Frisian, Middle Dutch he, hi, Dutch hy, Old High German he), from PIE *ki-, variant of *ko-, the "this, here" (as opposed to "that, there") root (cf. Hittite ki "this," Greek ekeinos "that person," Old Church Slavonic si, Lithuanian šis "this"), and thus the source of the third person pronouns in Old English. The feminine, hio, was replaced in early Middle English by forms from other stems (see she), while the h- wore off Old English neuter hit to make modern it. The Proto-Germanic root also is the source of the first element in German heute "today," literally "the day" (cf. Old English heodæg).

-masc.neut.fem.(all genders)
nom.hehitheo, hiohie, hi
acc.hinehithie, hihie, hi

Pleonastic use with the noun ("Mistah Kurtz, he dead") is attested from late Old English. With animal words, meaning "male" (he-goat, etc.) from c.1300.
