- \ \ [OE] He comes ultimately from a prehistoric Indo-European base *ki-, *ko-, which denoted in general terms ‘this, here’ (as opposed to ‘that, there’) and occurs in a number of modern English demonstrative pronouns and adverbs, such as here and hence. The most direct use of the demonstrative is for the ‘person or thing referred to’, and so *ki- has come down directly via Germanic *khi- as the third person singular pronoun he (of which him, his, she, her, and it are all derivatives).\ \ Cf.⇒ HIM, HIS, IT, SHE
