Present twitch acquired from blasphemer (7)
I believe the answer is:
heretic
'acquired from blasphemer' is the definition.
I can't judge whether this definition defines the answer.
'present twitch' is the wordplay.
'present' becomes 'here' ('here' can be similar in meaning to 'present').
'twitch' becomes 'tic' (tic is a kind of twitch).
'here'+'tic'='HERETIC'
Can you help me to learn more?
(Other definitions for heretic that I've seen before include "person not acting in good faith?" , "I wrongly believe" , "Original thinker" , "Person with views contrary to accepted beliefs" , "contrarian" .)
