Aim of mountaineering clubs attracting member ... (5)
I believe the answer is:
climb
'aim of mountaineering' is the definition.
The definition and answer can be both acts as well as being singular nouns.
Maybe there's a link between them I don't understand?
'clubs attracting member' is the wordplay.
'clubs' becomes 'c' (abbreviation in card games).
'attracting' means one lot of letters go next to another.
'member' becomes 'limb' (member can mean a limb).
'c'+'limb'='CLIMB'
Can you help me to learn more?
(Other definitions for climb that I've seen before include "mountaineer's intent?" , "Ascend, escalate" , "Soar" , "Use hands and feet to rise" , "increase" .)
