relic

I'm a little stuck... Click here to teach me more about this clue!

'something saved' is the definition.
I can't tell whether this definition defines the answer.

'from' acts as a link.

Can you help me to learn more?

(Other definitions for relic that I've seen before include "Revered religious remnant" , "Saint's body part?" , "Reminder of times past" , "Trace" , "Venerated memento" .)
