Hire unruly gang in gutless example (6)
I believe the answer is:
engage
'hire' is the definition.
(I know that engage is a more specific form of hire)
'unruly gang in gutless example' is the wordplay.
'unruly' indicates an anagram.
'in' is an insertion indicator.
'gutless' means to remove the middle letters.
'example' with its middle taken out is 'ee'.
'gang' with letters rearranged gives 'ngag'.
'ngag' inserted inside 'ee' is 'ENGAGE'.
(Other definitions for engage that I've seen before include "Allay" , "having to start a battle" , "Morally committed to" , "start fighting" , "Employ or take on" .)
