Can you give me the history behind the words "gender" and "sex" and the use of these words?
When have they been used to mean the same thing?
What are the earliest definitions of each word?
When, if ever, was it distinguished that there is a difference in the definitions of each word?
Do different organizations or groups of people use different definitions for the these words?
Were they originally meant to have different definitions, then later used to encompass similar characteristics, or was it the other way around?
