來源：
Middle English oughten [to be obliged to]
中古英文 oughten [受迫做…]
from oughte [owned]
源自 oughte [被擁有的]
from Old English 3hte [past tense of] 3gan [to possess] * see ôik-
源自 古英文 3hte [] 3gan的過去時 [擁有] *參見 ôik-

Ought to is sometimes used without a following verb if the meaning is clear:
如果意思明確，有時ought to 後面不需跟動詞：
例句：
Should we begin soonô Yes, we ought to.
我們馬上開始嗎ô 是的，開始。

In questions and negative sentences,especially those with contractions,to is also sometimes omitted:
在疑問句和否定句中，尤其是帶縮寫的這些句子中，to 有時也會被省略：
例句：
Oughtn`t we be going soonô
難道我們不馬上走嗎ô

Although the omission ofto was formerly possible in English, it is now considered nonstandard. ·Usages such asHe hadn`t ought to come and She shouldn`t ought to say that are common in many varieties of American English. They should be avoided in written English,however, in favor of the more standard variantought not to.
儘管以前在英文裡省略to 是可能的， 但現在這樣做就會被認為不標準。例如他不會來 和 她不該說 之類的用法在各種美式英文中很普遍。 但在書面英文中應避免這樣使用，而應使用更標準的變體ought not to
