Singer in the garden cut the short grass (6)
I believe the answer is:
thrush
'singer in the garden cut' is the definition.
'thrush' can be an answer for 'singer' (thrush is a kind of birdanimal). I'm not sure about the 'in the garden cut' bit.
'the short grass' is the wordplay.
'short' means to remove the last letter.
'grass' becomes 'rush' (I've seen this before).
'the' with its final letter taken away is 'th'.
'th'+'rush'='THRUSH'
Can you help me to learn more?
(Other definitions for thrush that I've seen before include "Bird that sings" , "Common singing bird or throat infection" , "Small songbird" , "Songbird - fungal infection" , "Singing bird or mouth-troat infection" .)
