Changing Category Titles

I'm brand new to Zoho. Looking to Zoho CRM and Zoho Creator together to build a practice managment system for my law practice. I am new to CRMs in general. The terminology used by Zoho of "accounts" and "cases" and such is somewhat foreign to the terminology lawyers are used to. Is there any way to customize my account to change to category titles? Could I change, by way of nonsensical example, "Potentials" to "Guys with Green Hats"?
