Wife promoted to head of a Jersey city? (4)
I believe the answer is:
waco
'jersey city?' is the definition.
I know nothing about this answer so I can't tell whether it can be defined by this definition.
'wife promoted to head of a' is the wordplay.
'wife' becomes 'w' (abbreviation).
'promoted' shows that the letters should be reversed in order (going up, in a down clue).
'to head of' becomes 'oc' (I can't explain this - if you can you should give a lot more credence to this answer).
'oc'+'a'='oca'
'oca' written backwards gives 'aco'.
'w'+'aco'='WACO'
Can you help me to learn more?
(Another definition for waco that I've seen is " Texas city linked to a 1993 siege and massacre".)
