either

• adj. 两者之中任一的；两者之中每一的
• prep. 任何一个
• conj. 也（用于否定句或否定词组后）；根本
• pron. 任一，两方，随便哪一个；两者中的一个或另一个

缩写自古英语aeghwaether, 来自ae, 词源同each. hwaether,同whether. 即两者中永远有一个。

1. after a negative statement used as an intensive meaning something like `likewise' or `also';

"he isn't stupid, but he isn't exactly a genius either"

"I don't know either"

"if you don't order dessert I won't either"

either

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.
=> aye, whether

either

Old English ægðer, contraction of æghwæðer (pron., adv., conj.) "each of two, both," from a "always" (see aye (adv.)) + ge- collective prefix + hwæðer "which of two, whether" (see whether). Cognate with Dutch ieder, Old High German eogiwedar, German jeder "either, each, every").

Modern sense of "one or the other of two" is late 13c. Adverbially, for emphasis, "in any case, at all," especially when expressing negation, by 1828. Use of either-or to suggest an unavoidable choice between alternatives (1931) in some cases reflects Danish enten-eller, title of an 1843 book by Kierkegaard.

also, too, as well, either, likewise

这些词均含"也"之意。

also：比too正式一些，语气较重，只用于肯定句，一般紧靠动词。

too：语气较轻，多用于口语，在肯定句中使用，通常位于句末。

as well：一般不用否定句，通常放在句末，强调时可放在句中。

either：用于否定句，放在句末，之前加逗号。

likewise：是书面语用词。

Either way, we have choices about how we respond to it when it comes.
