Climb with laces tangled? (5)
I believe the answer is:
scale
'climb' is the definition.
(I know that scale is a type of climb)
'laces tangled?' is the wordplay.
'tangled?' indicates an anagram.
'laces' with letters rearranged gives 'SCALE'.
'with' is the link.
(Other definitions for scale that I've seen before include "Ratio between size and representation, on map say" , "Relative size (of something)" , "Part of fish/reptile skin" , "Measure" , "See 23" .)
