Old hairpiece found in cable over in Tamworth? (7)
I believe the answer is:
periwig
'old hairpiece' is the definition.
(I've seen this in another clue)
'cable over in tamworth?' is the wordplay.
'cable' becomes 'wire' (synonyms).
'over' says the letters should be written backwards.
'in' is an insertion indicator.
'tamworth?' becomes 'pig' (Tamworth is a breed of pig).
'wire' backwards is 'eriw'.
'eriw' going within 'pig' is 'PERIWIG'.
'found in' acts as a link.
(Other definitions for periwig that I've seen before include "Peruke" , "Old kind of toupee" , "18th-century hairpiece" , "topping" , "Old rug" .)
