Subordinate and less sensitive as well, we hear (6,3)
I believe the answer is:
number two
'subordinate' is the definition.
Both the answer and definition are singular nouns.
Perhaps you can see a link between them that I don't see?
'less sensitive as well we hear' is the wordplay.
'less sensitive' becomes 'number' (numb means insensitive or unfeeling).
'as well' becomes 'too' (both can mean 'also').
'we hear' indicates a 'sounds like' (homophone) clue.
'too' is a homophone of 'two'.
'number'+'two'='NUMBER TWO'
'and' acts as a link.
Can you help me to learn more?
(Other definitions for number two that I've seen before include "Dump" , "Second in command" , "vice" , "Assistant" , "deputy" .)
