Sensible project idiotic extremists poisoned? (6)
I believe the answer is:
septic
'poisoned?' is the definition.
(I've seen this before)
'sensible project idiotic extremists' is the wordplay.
'sensible project' becomes 'sept' (I can't explain this - if you can you should believe this answer much more).
'extremists' says to hollow out the word (remove centre letters) (letters on the extreme ends of the word).
'idiotic' with its middle removed is 'ic'.
'sept'+'ic'='SEPTIC'
Can you help me to learn more?
(Other definitions for septic that I've seen before include "Putrid" , "Poisoned" , "Contaminated with disease-causing bacteria" , "Of wound, infected with pus" , "Type of tank" .)
