Climb noteworthily? (5)
I believe the answer is:
scale
'climb' is the definition.
(scaling is a kind of climbing)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for scale that I've seen before include "Part of fish/reptile skin" , "Group of notes in ascending or descending order" , "See 23" , "Climb; overlapping plate" , "Relative size (of something)" .)
