Point out piece of climbing equipment (5)
I believe the answer is:
piton
'piece of climbing equipment' is the definition.
'piton' can be an answer for 'equipment' (piton is a kind of equipment). I am not sure about the 'piece of climbing' bit.
'point out' is the wordplay.
'out' indicates an anagram (out can mean wrong or inaccurate).
'point' is an anagram of 'PITON'.
Can you help me to learn more?
(Other definitions for piton that I've seen before include "It helps the climber" , "Mountaineer's metal spike" , "Peg driven into rock as climbing support" , "Kind of rope-supporting peg used in rock-climbing" , "Metal peg used in rock climbing" .)
