Male to pursue in sidecar, perhaps (8)
I believe the answer is:
cocktail
'sidecar perhaps' is the definition.
(I know that Sidecar is a type of cocktail)
'male to pursue' is the wordplay.
'male' becomes 'cock' (male chicken).
'to pursue' becomes 'tail' (tailing is a kind of pursuing).
'cock'+'tail'='COCKTAIL'
'in' is the link.
(Other definitions for cocktail that I've seen before include "Possibly old-fashioned" , "Screwdriver, for example" , "dish with prawn" , "Manhattan, perhaps" , "Mixed beverage" .)
