Stop outside toilet getting installed (9)
I believe the answer is:
enthroned
'installed' is the definition.
The answer and definition can be both to do with social activities as well as being past participle verbs.
Perhaps there's an association between them I don't understand?
'stop outside toilet getting' is the wordplay.
'stop' becomes 'end' (synonyms).
'outside' means one lot of letters goes inside another (some letters go outside others).
'toilet getting' becomes 'throne' (I can't explain this - if you can you should believe this answer much more).
'end' enclosing 'throne' is 'ENTHRONED'.
Can you help me to learn more?
(Other definitions for enthroned that I've seen before include "Made bishop" , "Installed (as monarch)" , "Put in place" , "Honourably placed" .)
