Middle English bothe
中古英语 bothe
from Old English b3 th3 [both those]
源自 古英语 b3 th3 [那两个]
b3 [neuter of] bôgen [both]
b3 [] bôgen的中性 [两个]
th3 [plural of] thôt [that] * see that
th3 [] thôt的复数 [那] *参见 that

Both is used to indicate that the action or state denoted by the verb applies individually to each of two entities. Both books weigh more than five pounds, for example, means that each book weighs more than five pounds by itself,not that the two books weighed together come to more than five pounds.Both is inappropriate where the verb does not apply to each of the entities by itself. · In possessive constructionsof both is usually preferred: the mothers of both (rather than both their mothers ); the fault of both (rather than both their fault or both`s fault ). · Whenboth is used with and to link parallel elements in a sentence, the words or phrases that follow them should correspond grammatically:in both India and China or both in India and in China (not both in India and China ). See Usage Note at and
Both 用于表明动词意指的行为或状态，可单独用于两个实体中的任一个。 例如两本书均重于五磅， 意指每一本书自身即重过五磅，而不是两本书合起来才重过五磅。当动词不能单独用于实体中的任一个时，用both 是不恰当的。 在所有格结构中，of both 通常是更确切的： the monthers of both（他们的母亲） （而不是 both their monthers ）； the fault of both（他们的过错） （而不是 both their fault 或 both`s fault ）。 当both 与 and 在句子中用于连接平行成份时， 连接的词或短语应在语法上保持一致：in both India and China （在印度和中国）或 both in India and in China （而不是 both in India and China ） 参见 and
