Cute little bear sounded like a bird (7)
I believe the answer is:
tweeted
'sounded like a bird' is the definition.
I can't tell whether this defines the answer.
'cute little bear' is the wordplay.
'cute' becomes 'twee' (twee can mean cute or pretty).
'little bear' becomes 'ted' (teddy bear. I am not sure about the 'little' bit.).
'twee'+'ted'='TWEETED'
Can you help me to learn more?
(Other definitions for tweeted that I've seen before include "used social media?" , "Made a posting" .)
