Climbing frame exhausted Trevor Peters (the novelist) (7)
I believe the answer is:
trellis
'climbing frame' is the definition.
'trellis' can be an answer for 'frame' (trellis is a kind of frame). I'm unsure of the 'climbing' bit.
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for trellis that I've seen before include "Garden lattice" , "Garden support for climbers" , "Garden framework for climbers" , "Garden frame or screen" , "Support for climbing plants" .)
