It may help with a headache in Paris, perhaps (7)
I believe the answer is:
aspirin
'it may help with a headache' is the definition.
The definition suggests a singular noun which matches the answer. I also know that 'headache' relates to this answer.
'in paris perhaps' is the wordplay.
'perhaps' is an anagram indicator.
'in'+'paris'='inparis'
'inparis' is an anagram of 'ASPIRIN'.
Can you help me to learn more?
(Other definitions for aspirin that I've seen before include "Analgesic compound" , "Headache pill" , "Common analgesic drug" , "Anti-inflammatory tablet" , "number" .)
