Openers for Australia, maybe, in cricket match providing fewest thrills (6)
I believe the answer is:
tamest
'providing fewest thrills' is the definition.
I can't tell whether this definition defines the answer.
'openers for australia maybe in cricket match' is the wordplay.
'openers for' says to take the initial letters.
'in' is an insertion indicator.
'cricket match' becomes 'test' (a test is a kind of cricket match).
The initial letters of 'australia maybe' is 'am'.
'am' inserted inside 'test' is 'TAMEST'.
Can you help me to learn more?
(Other definitions for tamest that I've seen before include "Least wild, most domesticated" , "Least exciting" , "Most docile" , "Meekest or least wild" , "Most restrained or quiet" .)
