Where, in Mexico, Paul contrived to enter the electricity company (8)
I believe the answer is:
acapulco
'where in mexico' is the definition.
The answer is a location as well as being a singular noun. This is suggested by the definition.
'paul contrived to enter the electricity company' is the wordplay.
'contrived' indicates anagramming the letters.
'to enter' means one lot of letters goes inside another.
'the electricity' becomes 'ac' (AC is an example).
'company' becomes 'co' (abbreviation).
'paul' is an anagram of 'apul'.
'ac'+'co'='acco'
'apul' put into 'acco' is 'ACAPULCO'.
Can you help me to learn more?
