Kind of perch for a singer
I believe the answer is:
bass
This might be a double definition.
'kind of perch' is the first definition.
'bass' can be an answer for 'perch' (I've seen this before). I'm not sure about the 'kind of' bit.
'a singer' is the second definition.
(bass is a kind of singer)
'for' acts as a link.
Can you help me to learn more?
(Other definitions for bass that I've seen before include "bottom of sound?" , "Fish; vocalist" , "Type of fish" , "Sea perch - male voice" , "Male singer and saltwater fish" .)
