Male duck finally found next to garden tool (5)
I believe the answer is:
drake
'male duck' is the definition.
(I've seen this in another clue)
'finally found next to garden tool' is the wordplay.
'finally' suggests the final letters.
'next to' means one lot of letters go next to another.
'garden tool' becomes 'rake' (tool used when gardening).
The final letter of 'found' is 'd'.
'd'+'rake'='DRAKE'
(Other definitions for drake that I've seen before include "world traveller" , "Male duck - circumnavigator" , "Aquatic bird" , "Sir Francis - -" , "Navigator" .)
