either
Concise Oxford English Dictionary © 2008 Oxford University Press:
either /ˈʌɪðə, ˈiː-/
▶conjunction & adverb
- 1 used before the first of two (or occasionally more) alternatives specified (the other being introduced by ‘or’).
- 2 [adv., with neg.] used to indicate a similarity or link with a statement just made.
■ moreover.
■ each of two.
usage: In good English, it is important that either and or are correctly placed so that the structures following each word balance and mirror each other. Thus, sentences such as either I accompany you or I wait here and I'm going to buy either a new camera or a new video are correct, whereas sentences such as either I accompany you or John and I'm either going to buy a new camera or a video are not well balanced.
