For which we say golfer should be dismissed, oddly! (5)
I believe the answer is:
eagle
'for' is the definition.
Both the answer and definition are singular nouns.
Maybe you can see a link between them that I can't see?
'we say golfer should be dismissed oddly' is the wordplay.
'should be dismissed oddly' means one should take alternating letters (letters in odd-numbered positions removed).
'we'+'say'+'golfer'='wesaygolfer'
The alternating letters of 'wesaygolfer' are 'EAGLE'.
'which' is the link.
Can you help me to learn more?
(Other definitions for eagle that I've seen before include "Keen-eyed bird" , "may be soaring" , "Avian symbol of power" , "Score of two strokes under par for a golf hole" , "Keen-sighted bird of prey" .)
