Extremely tiresome TMS chat spoilt this? (4,5)
I believe the answer is:
test match
'this?' is the definition.
The definition suggests a singular noun which matches the answer.
'extremely tiresome tms chat spoilt' is the wordplay.
'extremely' means to remove the middle letters (only the extremes of the word are used).
'spoilt' is an anagram indicator.
'tiresome' with its middle removed is 'te'.
'tms'+'chat'='tmschat'
'tmschat' is an anagram of 'stmatch'.
'te'+'stmatch'='TEST MATCH'
Can you help me to learn more?
(Other definitions for test match that I've seen before include "International meeting" , "International contest" , "may be part of a series" , "may involve man dealing with maiden" , "International (esp. cricket)" .)
