US city for which itinerant oilman pines? (11)
I believe the answer is:
minneapolis
'us city' is the definition.
(I've seen this before)
'itinerant oilman pines?' is the wordplay.
'itinerant' is an anagram indicator (I've seen this in other clues).
'oilman'+'pines'='oilmanpines'
'oilmanpines' anagrammed gives 'MINNEAPOLIS'.
'for which' acts as a link.
(Other definitions for minneapolis that I've seen before include "City in Minnesota" , "US city" , "Saint Paul's twin city" .)
