Singer like this professional keeping a name (7)
I believe the answer is:
soprano
'singer' is the definition.
(soprano is a kind of singer)
'like this professional keeping a name' is the wordplay.
'like this' becomes 'so'.
'professional' becomes 'pro' ('pro' can be a synonym of 'professional').
'keeping' indicates putting letters inside.
'a name' becomes 'an' (I've seen this in other clues).
'pro' going around 'an' is 'prano'.
'so'+'prano'='SOPRANO'
(Other definitions for soprano that I've seen before include "Isolde, Violetta or 25" , "Singer of high notes" , "gangster" , "Female singing voice" , "Singer who aims high" .)
