A male in charge, having less feeling as a scientific figure (6,6)
I believe the answer is:
atomic number
'a scientific figure' is the definition.
The answer and definition can be both quantities as well as being singular nouns.
Perhaps there's an association between them I don't understand?
'a male in charge having less feeling' is the wordplay.
'male' becomes 'tom' (tom can mean a male cat).
'in charge' becomes 'ic' (abbreviation for 'in charge').
'having' is a charade indicator (letters next to each other).
'less feeling' becomes 'number' (more numb).
'a'+'tom'+'ic'+'number'='ATOMIC NUMBER'
'as' acts as a link.
Can you help me to learn more?
(Another definition for atomic number that I've seen is " Feature of element".)
