Fashionable English learner driver's one after Golf? (5)
I believe the answer is:
hotel
'one after golf?' is the definition.
(Hotel follows Golf in the NATO Phonetic Alphabet)
'fashionable english learner driver's' is the wordplay.
'fashionable' becomes 'hot' (hot can mean fashionable or trendy).
'english' becomes 'E' (abbreviation).
'learner driver' becomes 'l' (learner drivers have L-plates on their cars).
'hot'+'e'+'l'='HOTEL'
(Other definitions for hotel that I've seen before include "Building for travellers" , "offering accommodation" , "Eg, Savoy, Ritz" , "Holiday venue" , "sleeper" .)
