Please. Just say “function.” Maybe you really mean “usability,” or “usefulness.”
I had intended to write this post emphasizing that the word is not in the dictionary. Only it turns out it is: It’s an archaic word coined in 1871 and barely used again until it became the overused buzzword of the last year or so. Functionality is an awkward mouthful without adding any meaning.
Clear speech with no silly lingo. Your customers will thank you.
Grow and be well,
