either: [OE] Either is the modern descendant of an ancient Germanic phrase which meant literally ‘always each of two’. Its constituents were *aiwō, source of English aye ‘ever, always’, (which was also one of the building blocks of which each was made) and *gikhwatharaz, ancestor of English whether. In Old English this became lexicalized as the compound ǣgehwæther, subsequently contracted to ǣgther, from which developed modern English either. Despite its similarity, neither is more than just either with a negative prefix tacked on: its history is parallel but slightly different.
