Small gangs arranging an inside job in stir? (5)
I believe the answer is:
trios
'small gangs' is the definition.
The definition and answer can be both groups as well as being plural nouns.
Maybe you can see a link between them that I can't see?
'arranging an inside job in stir?' is the wordplay.
'arranging' becomes 'putting' ('put' can be a synonym of 'arrange').
'an inside' indicates the central letters.
'job in stir?' becomes 'rios' (I can't explain this - if you can you should give a lot more credence to this answer).
The central letter of 'putting' is 't'.
't'+'rios'='TRIOS'
Can you help me to learn more?
(Other definitions for trios that I've seen before include "Works for three players" , "Groups of three" .)
