Poles are capable of catching you! (5)
I believe the answer is:
snare
'capable of catching you' is the definition.
I can't tell whether this defines the answer.
'poles are' is the wordplay.
'poles' becomes 'SN' (North and South poles).
'sn'+'are'='SNARE'
Can you help me to learn more?
(Other definitions for snare that I've seen before include "part of a musician's kit" , "Catch" , "Wire on drum; trap" , "Noosed trap" , "Kind of trap, often with noose" .)
