Which relative, not husband, is a solver's partner? (6)
I believe the answer is:
watson
'a solver's partner?' is the definition.
I can't judge whether this defines the answer.
'which relative not husband' is the wordplay.
'which' becomes 'what' (I've seen this in other clues).
'relative' becomes 'son' (son is a kind of relative).
'not' suggests deleting specific letters.
'husband' becomes 'h'.
'what'+'son'='whatson'
'whatson' with 'h' taken away is 'WATSON'.
'is' acts as a link.
Can you help me to learn more?
(Other definitions for watson that I've seen before include "Sherlock Holmes's doctor companion" , "Sherlock Holmes's doctor buddy" , "Holmes' associate" , "Holmes's assistant" , "Companion to 15 ac" .)
