English cricketer ultimately caught by Germans out for a duck (9)
I believe the answer is:
merganser
'a duck' is the definition.
(merganser is a kind of duck)
'english cricketer ultimately caught by germans out' is the wordplay.
'english' becomes 'e' (abbreviation).
'ultimately' indicates one should take the final letters.
'caught by' means one lot of letters goes inside another.
'out' is an anagram indicator (out can mean wrong or inaccurate).
The last letter of 'cricketer' is 'r'.
'e'+'r'='er'
'germans' anagrammed gives 'mganser'.
'er' going within 'mganser' is 'MERGANSER'.
'for' acts as a link.
(Other definitions for merganser that I've seen before include "Together saw bill" , "Diving bird" , "Sawbill" , "Diver" , "Diving duck" .)
