Some raucous noise reflected current elements (4)
I believe the answer is:
ions
'current elements' is the definition.
Although both the answer and definition are plural nouns, I don't understand how they can define each other.
'some raucous noise reflected' is the wordplay.
'some' indicates a hidden word (some of the parts of the word are used).
'reflected' is a reversal indicator (letters reflected back).
'snoi' is hidden within 'raucous noise'.
'snoi' reversed gives 'IONS'.
Can you help me to learn more?
(Other definitions for ions that I've seen before include "N in radio comms." , "Charged atom or molecule" , "Electrically-charged particles" , "Electrically charged particles" , "items with a charge" .)
