System put in place to water down European capital overwhelmed violently in riot (10)
I believe the answer is:
irrigation
'system put' is the definition.
The answer and definition can be both acts as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'in place to water down european capital overwhelmed violently in riot' is the wordplay.
I cannot really see how this works, but
'capital' could be 'riga' (Riga is an example) and 'riga' is found within the answer.
an anagram of 'riot' is 'rtio' which is present in the remaining letters.
'in' is found in the answer.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for irrigation that I've seen before include "The supply of water to crops" , "an answer to all clues, initially" , "watering process" , "water distribution" .)
