Wishing I’ll give you a lift to golf (6)
I believe the answer is:
hoping
'wishing' is the definition.
(hoping is a kind of wishing)
'i'll give you a lift to golf' is the wordplay.
'i'll give you a lift' becomes 'hopin' ('hop in' is used to offer someone a lift in a car).
'to golf' becomes 'g' (phonetic alphabet: alpha, bravo, charlie etc.).
'hopin'+'g'='HOPING'
(Other definitions for hoping that I've seen before include "Trusting, expecting" , "Expecting and wishing" , "Desiring with an expectation of success" , "Having wish or desire for" .)
