Remove moggies, discharging a fire extinguisher — it’s all kinds of sport! (9)
I believe the answer is:
decathlon
'sport' is the definition.
(thesaurus)
'remove moggies discharging a fire extinguisher it's all kinds of' is the wordplay.
I cannot quite see how this works, but
'remove' could be 'de' (I've seen this in other clues) and 'de' is located in the answer.
'a' is found in the answer.
'of' could be 'o' and 'o' is located in the answer.
'it' could be 't' (abbreviation. e.g. in 'tis) and 't' is found within the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for decathlon that I've seen before include "Athletics contest" , "Olympic athletics event" , "Competition comprising ten events" , "Athletic event" , "Sporting event with 10 disciplines" .)
