It can give us (and be given) a song (6)
I believe the answer is:
thrush
'a song' is the definition.
Although both the answer and definition are singular nouns, I cannot see how one could define the other.
'it can give us and be' is the wordplay.
I cannot quite see how this works, but
'it' could be 't' (abbreviation. e.g. in 'tis) and 't' is found within the answer.
'us' is within the answer.
The remaining letters 'hrh' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
'given' acts as a link.
Can you help me to learn more?
(Other definitions for thrush that I've seen before include "Singing bird or mouth-troat infection" , "Small bird - fungal mouth infection" , "Common singing bird or throat infection" , "Small songbird" , "Bird that sings" .)
