Murphy and maybe Pat too (6)
I believe the answer is:
potato
'murphy' is the definition.
(synonyms)
'maybe pat too' is the wordplay.
'maybe' indicates an anagram.
'pat'+'too'='pattoo'
'pattoo' with letters rearranged gives 'POTATO'.
'and' is the link.
(Other definitions for potato that I've seen before include "French wine region" , "The vegetable is too apt, oddly" , "The humble spud" , "Root crop" , "Would be difficult to deal with if hot" .)
