Opponent of modernisation did wrong breaking into instrument (7)
I believe the answer is:
luddite
'opponent of modernisation' is the definition.
'luddite' can be an answer for 'opponent' (I have seen 'Opponent of progress ' mean 'luddite' so perhaps 'opponent' could also mean 'luddite'). I am unsure of the 'of modernisation' bit.
'did wrong breaking into instrument' is the wordplay.
'wrong' is an anagram indicator.
'breaking into' indicates putting letters inside.
'instrument' becomes 'lute' (lute is a kind of instrument).
'did' is an anagram of 'ddi'.
'ddi' put inside 'lute' is 'LUDDITE'.
Can you help me to learn more?
(Other definitions for luddite that I've seen before include "Opposer of mechanisation" , "One resisting technology progress" , "Early nineteenth century anti-machinery demonstrator" , "One of a gang of English workmen destroying labour-saving mill machinery, 1811-16" , "Person who opposes the introduction of new technology" .)
