Joey said that line to himself after being corrected by Chandler on the use of supposedly vs. supposably.Joey from Friends said:Did they go to the zoo? Supposably...
Now I always though that supposedly was the correct usage and that supposably wasn't even a real word. A couple of nights ago, while eating at a local restaurant, I overheard part of a conversation at the next table, where an older woman used the word supposably. I chuckled to myself, thinking of that scene from Friends. The next day I decided to look up both words online, and saw that both are valid words, according to Merriam-Webster.com.
Are these two words interchangeable? Was Chandler wrong for correcting Joey?
