Tate perhaps cured allergy (7)
I believe the answer is:
gallery
'tate' is the definition.
Both the definition and answer are singular nouns.
Maybe they are linked in a way I don't understand?
'cured allergy' is the wordplay.
'cured' indicates an anagram.
'allergy' anagrammed gives 'GALLERY'.
'perhaps' acts as a link.
Can you help me to learn more?
(Other definitions for gallery that I've seen before include "Group of spectators" , "Long passage" , "Eg, the Tate" , "Building for works of art" , "eg National, Hayward" .)
