I have to define the meaning of liberty. I know the basics of what it means, but I need some help to make it deeper.

Thank you for using the Jiskha Homework Help Forum. It's always a good idea to begin with a definition from a good dictionary:

Main Entry: lib·er·ty
Pronunciation: 'li-b&r-tE
Function: noun
Inflected Form(s): plural -ties
Etymology: Middle English, from Middle French liberté, from Latin libertat-, libertas, from liber free —more at LIBERAL

Now, to make it "deeper" consider what it means to you!
