Poet, fat and benevolent, neglecting daughters (6)
I believe the answer is:
larkin
'poet' is the definition.
(Philip Larkin)
'fat and benevolent neglecting daughters' is the wordplay.
'fat' becomes 'lard' (lard is a kind of fat).
'and' means one lot of letters go next to another.
'benevolent' becomes 'kind' (associated in meaning).
'neglecting' indicates named letters should be taken away.
'daughters' becomes 'dd' (two abbreviations for daughter).
'lard'+'kind'='lardkind'
'lardkind' with 'dd' taken away is 'LARKIN'.
(Other definitions for larkin that I've seen before include "English poet, 1922-85" , "Orchestral violins, violas, cellos and basses" , "Philip ---, C twenty English poet" , "Coventry-born poet associated with Hull" , "Big Jim . . . . . . was a great trade union leader" .)
