Disrupting loud pastime (4)
I believe the answer is:
ludo
'pastime' is the definition.
The definition and answer can be both acts as well as being singular nouns.
Maybe there's a link between them I don't understand?
'disrupting loud' is the wordplay.
'disrupting' indicates anagramming the letters.
'loud' with letters rearranged gives 'LUDO'.
Can you help me to learn more?
(Other definitions for ludo that I've seen before include "Traditional board game" , "Loud sort of board game with dice and counters" , "race for four tokens" , "Children's board game" , "Race game" .)
