Fragen über die Beispielsätze mit, und die Definition und Benutzung von "Supposably"

A: Some people believe that supposably means that something is held in some specific regard or that something is capable to being thought of in some fashion. This house is supposably haunted.
I disagree. I believe it is just a common mispronunciation of the word supposedly. Which means simply that something is a suppletion. This house is supposedly haunted.

A: I have never heard the word "supposably" used correctly as a native English speaker. I thought it wasn't an actual word but I looked it up and it is. Supposedly means according to what is believed to be true. An example would be: "Supposedly there 3 lions at the zoo." There is doubt involved with this. In this case the speaker is unsure if there is really three lions at the zoo. I had to look "supposably" up. In simplest terms supposedly conveys doubt, supposably doesn't. But unless you are talking to someone with a quite expansive vocabulary you will never use the word supposably.
