Could this city be Tangier? (7)
I believe the answer is:
granite
'could this city' is the definition.
Although both the answer and definition are singular nouns, I don't see how they can define each other.
'tangier?' is the wordplay.
'tangier' can be anagrammed to 'GRANITE'.
However, I am not clear how the anagram is indicated.
'be' is the link.
Can you help me to learn more?
(Other definitions for granite that I've seen before include "Hard granular rock" , "determination" , "Resilience; stone" , "Coarse-grained igneous rock" , "Very hard type of rock" .)
