Turf extremists out of home in sinful city (5)
I believe the answer is:
sodom
'sinful city' is the definition.
(I've seen this in another clue)
'turf extremists out of home' is the wordplay.
I cannot quite see how this works, but
'turf' could be 'sod' (both can mean a piece of grass) and 'sod' is present in the answer.
'of' could be 'o' and 'o' is present in the answer.
A single letter 'm' remains which might be clued in a way I don't understand.
This explanation may well be incorrect...
'in' acts as a link.
Can you help me to learn more?
(Other definitions for sodom that I've seen before include "place of utter depravity" , "den of vice" , "One of the biblical city destroyed for its wickedness" , "The piece of turf starts the wicked city" , "Vicious city" .)
