Irate about work, that chap's one suffering a shock (7)
I believe the answer is:
mophead
'one suffering a shock' is the definition.
I don't know anything about this answer so I can't judge whether this works.
'irate about work that chap's' is the wordplay.
'irate' becomes 'mad' (I've seen this in another clue).
'about' is an insertion indicator.
'work' becomes 'op' (abbreviation for opus).
'that chap' becomes 'he'.
'op'+'he'='ophe'
'mad' placed around 'ophe' is 'MOPHEAD'.
Can you help me to learn more?
(Other definitions for mophead that I've seen before include "one shocked" , "One with unkempt hair" .)
