Hamlet provides partner for Louise (6)
I believe the answer is:
thelma
'partner for louise' is the definition.
The definition suggests a singular noun which matches the answer.
'hamlet provides' is the wordplay.
'provides' is an anagram indicator.
'hamlet' is an anagram of 'THELMA'.
Can you help me to learn more?
(Other definitions for thelma that I've seen before include "Charge with gas" , "Louise's partner" , "-- and Louise, 1991 film" , "Girl" , "Foreign policy of force" .)
