Being old-fashioned, you, to an extent, loathe electricity (4)
I believe the answer is:
thee
'being old-fashioned' is the definition.
I don't know anything about this answer so I cannot tell whether this works.
'to an extent loathe electricity' is the wordplay.
'to an extent' indicates a hidden word (I've seen 'extent of' mean this (I've seen this in other clues)).
'THEE' is hidden in the letters of 'loathe electricity'.
'you' is the link.
Can you help me to learn more?
(Other definitions for thee that I've seen before include "'U'" , "Archaic form of 'you'" , "Poetically you" , "you many years ago" , "You in the olden days" .)
