I was composing an email and needed the plural form of the word "functionality." To my surprise I saw the dreaded red underline indicating a spelling mistake.
It made me wonder whether this was a false alarm. I searched for the word and found it being used at www.thefreedictionary.com
It then struck me that this was the browser's fault, as it comes with a spell checker. (Initially, I thought it was Gmail's fault).
Which brings me to my query: Is it wrong to pluralize "functionality?"
