Cry when shut out of the job centre (5)
I believe the answer is:
shout
'cry' is the definition.
(synonyms)
'shut out of the job centre' is the wordplay.
'out of' means one lot of letters goes inside another (some letters on the outside of others).
'centre' means to look at the middle letters.
The central letter of 'job' is 'o'.
'shut' placed around 'o' is 'SHOUT'.
'when' is the link.
(Other definitions for shout that I've seen before include "Yell" , "bellow" , "Utter a loud cry" , "(Statement) with opposite sense intended" , "Call loudly" .)
