Artificial intelligent assistant

either

either, a. (pron.) and adv. (conj.)
  (ˈiːðə(r), ˈaɪðə(r))
  Forms: 1 ǽᵹ-, œ́ᵹ-, éᵹhwæðer, 1–2 ǽᵹðer, 2 eiᵹðer, (3 Orm. eȝȝðer), 3 æiðer, aieþer, 2–4 eiðer, eiþer, 3–5 aiþer, aither, ayther, (ayder, 5 eyder), 3–6 ether, (? 4–6 aþer, ather, -ir, 4 euther, ewther), 3–7 eyther, -thir, (5 eithar), 6 eather, 4– either. See also er.
  [OE. ǽᵹhwæðer (contracted ǽᵹðer) = OHG. eogihwedar (MHG. iegeweder), f. WGer. *aiwo(n (in OE. á, ó) ay, always + *gihwaþaro-z (in OE. ᵹehwæðer: see y- and whether) each of two.
  In OE. and early ME. the word appears only in its original sense ‘each of two’, or as adv. = ‘both’; but about the beginning of 14th c. it assumed the disjunctive sense ‘one or the other of two’ (and the corresponding adverbial use), which properly belonged to OE. áhwæðer, áwðer, ME. owþer, oþer (see outher). This disjunctive sense has so far prevailed that in mod.Eng. such expressions as on either side = ‘on both sides’ are felt to be somewhat arch., and must often be avoided on account of their ambiguity. The word outher became obs. in literary use in 16th c.; its mod. dial. forms (pronounced ɔːðə(r)) are popularly regarded as belonging to either. (It is not quite clear whether the forms aþer athir in Sc. from 14th to 16th c. should not be referred to outher; cf. OE. áðor.)
  The pronunciation (ˈaɪðə(r)), though not in accordance with the analogies of standard Eng., is in London somewhat more prevalent in educated speech than (ˈiːðə(r)). The orthoepists of 17th c. seem to give (ˈɛːðər, ˈeːðər); Jones 1701 has (ˈeːðər) and (ˈaɪðər), Buchanan (1766) has (ˈaɪðə(r)) without alternative (see Ellis, Early Eng. Pron. ix, x.). Walker (1791) says that (ˈiːðə(r)) and (ˈaɪðə(r)) are both very common, but gives the preference to the former on the ground of analogy and the authority of Garrick. Smart (1849) says that ‘there is little in point of good usage to choose’ between the two pronunciations, though in the body of his dictionary he, like earlier orthoepists, gives (ˈiːðə(r)) without alternative.]
