Triumphant exclamation from a bowler, maybe, cut short (3)
I believe the answer is:
aha
'triumphant exclamation' is the definition.
'aha' can be an answer for 'exclamation' (I have seen 'Exclamation of discovery ' mean 'aha' so perhaps 'exclamation' could also mean 'aha'). I'm not certain of the 'triumphant' bit.
'a bowler maybe cut short' is the wordplay.
'bowler maybe' becomes 'hat' (bowler is a type of hat).
'cut short' means to remove the last letter.
'hat' with its final letter taken away is 'ha'.
'a'+'ha'='AHA'
'from' is the link.
Can you help me to learn more?
(Other definitions for aha that I've seen before include "I've got it!" , "I'm surprised" , "I get it!" , "Exclamation of triumph or surprise, a palindrome" , "I see!" .)
