New cryptic clue on some small matter (7)
I believe the answer is:
nucleon
'some small matter' is the definition.
Although both the answer and definition are singular nouns, I don't understand how they can define each other.
'new cryptic clue on' is the wordplay.
'new' becomes 'n' (common abbreviation eg NT for New Testament).
'cryptic' indicates an anagram (a cryptic or obscure order of the letters).
'clue' with letters rearranged gives 'ucle'.
'n'+'ucle'+'on'='NUCLEON'
Can you help me to learn more?
(Other definitions for nucleon that I've seen before include "fundamental constituent" , "Particle" .)
