One leaving riotous Dáil Eireann in something of a rush? (10)
I believe the answer is:
adrenaline
'one leaving riotous dail eireann' is the definition.
Although both the answer and definition are singular nouns, I can't see how one could define the other.
'in something of a rush?' is the wordplay.
I cannot really understand how this works, but
'in' is within the answer.
'a' is present in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for adrenaline that I've seen before include "Stimulating hormone" , "It stimulates" , "Hormone replacement" .)
