Usage notes

[edit]
  • Functions as a passive participial adjective, historically derived from the past participle of suppose, and behaves similarly to a passive/past participle in terms of grammar. Thus, it is typically preceded by a form of be, but not invariably so; see Citations:supposed to.
  • Always followed by the infinitive form of a verb, if not omitted by ellipsis. Historically, the construction consisted of supposed followed by a to-infinitive.
  • Often implies that the opposite is a strong possibility.
  • When used with the sense "considered to" or "believed to", there is not always a clear distinction between this expression and the past participle of the ordinary verb suppose.
