Qualified people like this singer (5)
I believe the answer is:
basso
'singer' is the definition.
(I know that basso is a type of singer)
'qualified people like this' is the wordplay.
'qualified people' becomes 'b' (I can't justify this - if you can you should give a lot more credence to this answer).
'like this' becomes 'as so' ('as so' can mean 'in this way').
'b'+'asso'='BASSO'
Can you help me to learn more?
(Other definitions for basso that I've seen before include "Singer" , "one's deep in sound" , "low voice" , "Lowest male singing voice (sometimes 'profundo')" .)
