A trick to cheat some cadgers (5)
I believe the answer is:
dodge
'a trick' is the definition.
(I've seen this before)
'cheat some cadgers' is the wordplay.
'cheat' becomes 'do'.
'some' says to take the centre.
The middle letters of 'cadgers' are 'dge'.
'do'+'dge'='DODGE'
'to' is the link.
(Other definitions for dodge that I've seen before include "Avoid or attempt to" , "Step sideways to evade" , "Avoid; cunning trick" , "Duck, move to avoid" , "Evade cunningly" .)
