Prisoner has inclination to get mountaineering gear (7)
I believe the answer is:
crampon
'mountaineering gear' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Perhaps you can see a link between them that I don't see?
'prisoner has inclination' is the wordplay.
'prisoner' becomes 'con' (abbreviation for 'convict').
'has' means one lot of letters goes inside another.
'inclination' becomes 'ramp' (an inclined surface).
'con' going around 'ramp' is 'CRAMPON'.
'to get' acts as a link.
Can you help me to learn more?
(Other definitions for crampon that I've seen before include "Climbing device" , "Spiked plate for a climbing boot" , "Climber's device" , "Climber's aid" , "Climbing aid on boot" .)
