Hi all! I understand this is a super niche topic, but recently, while trying to title a piece of work I'm writing, I wanted to use the noun form of 'Nefarious', which I assumed was 'Nefarity'. Just to be certain, I googled it, and it appears that the adjective form is, instead 'Nefariousness'. Upon googling "Why nefariousness instead of nefarity", I stumbled across this forum, though not with an answer to the question, just with the word 'Nefarity' in use. So, I pose the question (that is ever so slightly driving me mad);
Why nefariousness instead of nefarity?
Nefarity seems to make much more sense. It's shorter, more concise, and far less of a mouthful. While I love the English language, I'm not entirely sure if there's any rule that dictates when to use 'nous' instead of 'ity'. Generous, for example, becomes 'Generosity' and 'Generousness', but we don't use 'Generousness' often at all. Was the noun originally 'Generousness', and the common noun became 'Generosity' out of just the changes in our language, and it being easier to say and write? If so, is the same possible for 'Nefarity', or do we think that 'Nefariousness' itself is too uncommon to be used enough for us to make the switch to 'Nefarity'?
Furthermore, if I was to begin using ONLY nefarity, could I start a revolution and bring the word into common use?
