Article about rugby involving too much silence (8)
I believe the answer is:
throttle
'silence' is the definition.
(thesaurus)
'article about rugby involving too much' is the wordplay.
I cannot quite understand how this works, but
'too much' could be 'ott' (short for 'over the top' - informal British) and 'ott' is present in the answer.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for throttle that I've seen before include "Choke, strangle" , "Valve regulating volume of fuel and air" , "Check" , "Choke by pressure on the windpipe" , "what regulates flow of juice?" .)
