What are the 7 deadly sins and give me a brief definition please?

I'm researching the 7 deadly sins for a book I'm writing. I know what they are but I need a brief definition of Luxuria(Lust) , Gula (Gluttony), Superbia (Pride), Invidia (Envy), Avaritia (Greed), Acedia (Sloth), and Ira (Wrath). No scripts from the bible please! This is all for unreligious reasons.
