who
Etymology
From Middle Englishwho, hwo, huo, wha, hwoa, hwa, from Old Englishhwā (dative hwām, genitive hwæs), from Proto-West Germanic*hwaʀ, from Proto-Germanic*hwaz, from Proto-Indo-European*kʷos, *kʷis.
The sound change /hw/ > /h/ (without a corresponding change in spelling) was due to wh-cluster reduction after an irregular change of /ɑː/ to /oː/ in Middle English (instead of the expected /ɔː/) and further to /uː/ regularly in Early Modern English. A similar change occurred in two. Compare how, which underwent wh-reduction earlier (in Old English), and thus is spelt with h.

Usage notes
Who is a subject pronoun. Whom is an object pronoun. To determine whether a particular sentence uses a subject or an object pronoun, rephrase it to use he/she/they or him/her/them instead of who, whom; if you use he, she or they, then you use the subject pronoun who; if you use him, her or them, then you use the object pronoun. The same rule applies to whoever/whosoever/whoso and whomever/whomsoever/whomso. In the case of who(m)(so)ever, which usually plays a role in two phrases at once, it is the role in the internal ("downstairs") clause that determines the case. For example, Sell the sofa towhoeveroffers the most money for it uses whoever because it is the subject of the verb offers; the fact that it is also the object of to is irrelevant.
Who can also be used as an object pronoun, especially in informal writing and speech (hence one hears not only whom are you waiting for? but also who are you waiting for?), and whom may be seen as (overly) formal; in some dialects and contexts, it is hardly used, even in the most formal settings. As an exception to this, fronted prepositional phrases almost always use whom, e.g. one usually says with whom did you go?, not *with who did you go?. However, dialects in which whom is rarely used usually avoid fronting prepositional phrases in the first place (for example, using who did you go with?).
The use of who as an object pronoun is proscribed by many authorities, but is frequent nonetheless. It is usually felt to be much more acceptable than the converse hypercorrection in which whom is misused in place of who, as in *the savage whom spoke to me.
For more information, see "who" and "whom" on Wikipedia.
When “who” (or the other relative pronouns “that” and “which”) is used as the subject of a relative clause, the verb typically agrees with the antecedent of the pronoun. Thus “I who am...”, “He who is...”, “You who are...”, etc.
