Sennett's Normand married Magwitch? (5)
I believe the answer is:
mabel
'sennett's normand' is the definition.
I can't tell whether this defines the answer.
'married magwitch?' is the wordplay.
'married' becomes 'm' (abbreviation, e.g. in genealogy).
'magwitch?' becomes 'abel' (I've seen this before).
'm'+'abel'='MABEL'
Can you help me to learn more?
(Other definitions for mabel that I've seen before include "maid in 'Separate Tables'" , "Girl's name" , "Female name deriving from one meaning lovable" , "Female name; rhymes with mythic story" , "Lady" .)
