Channel originally cancelled feature (5)

I believe the answer is:
trait
'feature' is the definition.
(I've seen this before)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for trait that I've seen before include "Mannerism" , "Attribute, characteristic" , "Idiosyncrasy" , "Decorative band" , "Distinguishing characteristic of personality" .)
