Supposedly is the dictionary-approved word for believed or reputed to be the case. Supposably is a colloquial variant that may be considered out of place in formal writing.

Of course, supposably is technically a word—an adverb derived from supposable, which means capable of being supposed, which is significantly different from the meaning of supposed—but we can find no recent examples of the word used in this sense.

  1. In rare cases, a thing could be supposed, but no one really supposed it.

    Those are the only cases in which “supposably” is preferable to “supposedly”.

    But most people do not grasp the difference.
