The way one moans about a craftsman? (10)
I believe the answer is:
stonemason
'a craftsman?' is the definition.
(stonemason is a kind of craftsman)
'the way one moans about' is the wordplay.
'the way' becomes 'st'.
'about' indicates anagramming the letters.
'moans' with letters rearranged gives 'mason'.
'st'+'one'+'mason'='STONEMASON'
(Other definitions for stonemason that I've seen before include "manual worker" , "Building worker" , "chipper?" , "Rock craftsman" , "Architectural carver" .)
