What Is "Case"?
Imagine you are writing a school assignment. Sometimes you write:
BIG LETTERS LIKE THIS small letters like this Or MixEd LeTTeRs like ThIs
These styles of writing letters are called cases.
UPPERCASE means BIG letters
lowercase means small letters
Title Case means Every Word Starts With A Big Letter
Sentence case means only the first letter is big, like in a normal sentence
So when we talk about "case," we are talking about the style of letters.
