A contributor on a Facebook writers’ group posed a question today about when to use the word “supposably” instead of “supposedly.” My gut reaction was to reply that “supposably” was slang. Fortunately, I decided to Google the word and to my amazement found this:
Supposably means “as may be conceived or imagined” and is the adverb form of supposable, which means “capable of being supposed or conceived.” On the other hand, supposedly usually means “allegedly.” The words are often conflated when one usually intends to say “supposedly.”
All I have to say is”Holy Wordsmithing, Batman!”
Now, a good many folks who commented on the post refused to believe the Google entry. They preferred to stick with old knowledge. Supposedly they’d be the ones who supposably might ignore the importance of vaccines leading to dire consequences.
I have no idea if I used the word “supposably” correctly or not. It’s a tricky one and I’ll probably ignore it from now on. Still, it is a word, so don’t disrespect it.

Peace, people!
