Opening omitted from writing about obscure source of terror? (9)
I believe the answer is:
extremist
'source of terror?' is the definition.
The answer and definition can be both people as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'opening omitted from writing about obscure' is the wordplay.
I cannot quite understand how this works, but
'from' could be 'e' (I've seen this in other clues) and 'e' is found within the answer.
'writing' could be 'r' (one of the traditional three R's of education) and 'r' is found within the answer.
'obscure' could be 'mist' (synonyms) and 'mist' is found in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for extremist that I've seen before include "One with views far from the mainstream" , "One with very radical views" , "One with highly non-standard views" , "Fanatic, hardliner" , "One with views very far from consensus" .)
