Cities fail badly in opportunities (10)
I believe the answer is:
facilities
'opportunities' is the definition.
Although both the answer and definition are plural nouns, I cannot understand how one could define the other.
'cities fail badly' is the wordplay.
'badly' is an anagram indicator.
'cities'+'fail'='citiesfail'
'citiesfail' anagrammed gives 'FACILITIES'.
'in' is the link.
Can you help me to learn more?
(Other definitions for facilities that I've seen before include "amenities" , "Services" .)
