Report about rockface and one's climbing framework (7)
I believe the answer is:
trellis
'framework' is the definition.
(trellis is a kind of framework)
'report about rockface and one's climbing' is the wordplay.
I cannot really see how this works, but
'about' could be 're' ('re' means regarding or about) and 're' is present in the answer.
'one's' could be 'is' (Roman numeral) and 'is' is found within the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for trellis that I've seen before include "Garden climbing frame" , "latticework in the garden" , "Garden lattice" , "Support for climbing plants" , "Latticework support for plants" .)
