Alcoholic drink from the woman beginning to renationalise railway (6)
I believe the answer is:
sherry
'alcoholic drink' is the definition.
(I've seen this before)
'the woman beginning to renationalise railway' is the wordplay.
'the woman' becomes 'she' (I've seen this before).
'beginning to' says to take the initial letters.
'railway' becomes 'ry' (abbreviation for railway).
The first letter of 'renationalise' is 'r'.
'she'+'r'+'ry'='SHERRY'
'from' is the link.
(Other definitions for sherry that I've seen before include "Fortified 1 down [WINE]" , "Alcoholic appetiser associated with Jerez" , "Oloroso or amontillado?" , "Jerez tipple" , "Wine from the Jerez region of Spain" .)
