使用する際の注意点

• Ought is an auxiliary verb; it takes a following verb as its complement. This verb may appear either as a full infinitive (such as "to go") or a bare infinitive (such as simple "go"), depending on region and speaker; the same range of meanings is possible in either case. Additionally, it's possible for ought not to take any complement, in which case a verb complement is implied, as in, "You really ought to [do so]."
