Complex words ending with 'ity' with cool meaning?

Honestly I HAVE searched on the web for hours for complex words in general that are uncommon and yet have cool meanings. I've decided to narrow it down to just words ending with 'y', 'ity', 'city', and 'sity' since I like the sound of them. Could anyone please list or direct me to a site that has words ending with these that are UNCOMMON and have their definitions? Please and thank you. [Not common such as insanity, intensity, etc.] I prefer words that have some "strong" feeling to them but if you could help, I greatly appreciate it! Thank you!
