Diluted cocktail for technophobe (7)
I believe the answer is:
luddite
'technophobe' is the definition.
(I've seen this in another clue)
'diluted cocktail' is the wordplay.
'cocktail' is an anagram indicator.
'diluted' is an anagram of 'LUDDITE'.
'for' is the link.
(Other definitions for luddite that I've seen before include "Person who opposes the introduction of new technology" , "Worker who opposed mechanisation" , "One opposed to new technology" , "Opposer of mechanisation" , "Destroyer of machines" .)
