Drink fill then get something to drive? (8)
I believe the answer is:
download
'get something to drive?' is the definition.
(get something to a hard drive)
'drink fill' is the wordplay.
'drink' becomes 'down' (downing is a kind of drinking**).
'fill' becomes 'load' (loading is a kind of filling).
'down'+'load'='DOWNLOAD'
'then' is the link.
(Other definitions for download that I've seen before include "Information accessed" , "Transfer material from one computer to another" , "Copy data from Internet" , "something applied to your phone" .)
