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.

Word Origin and History for he's

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)

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.
