Tutoring English, spelling can hold surprises. The tutor mentions one he got from spelling “disfunctional.”
This editor is unhappy with the spelling “disfunctional”, yet Merriam-Webster does allow for it. Given that Merriam-Webster is American, and so I’m sure is this editor, I’m playfully surprised.
Neither of my Canadian dictionaries allows for “disfunctional”; rather, they both insist on “dysfunctional.”
