What is the meaning of "that" in the following sentence,
"I am about to reveal something to you that has taken me months to work up the nerve to confess"
?
Does that mean "To revel something to you" ?
Does it mean "I am about to reveal something to you. To reveal something to you has taken me months to work up the nerve to confess " ?
If so, I would be grateful if you could introduce some examples that are used in this way.
