We tamper with ticker and keep the one behind the stumps (12)
I believe the answer is:
wicketkeeper
'we tamper with ticker' is the definition.
I can't judge whether this defines the answer.
'keep the one behind the stumps' is the wordplay.
'keep the one' becomes 'keeper' (I can't explain this - if you can you should believe this answer much more).
'behind' says to put letters next to each other.
'the stumps' becomes 'wicket' (I've seen this before).
'keeper' put after 'wicket' is 'WICKETKEEPER'.
'and' is the link.
Can you help me to learn more?
(Other definitions for wicketkeeper that I've seen before include "Stumper" , "Fielder behind stumps" , "Close fielder" , "Cricket player" , "Cricketer" .)
