Batch of offspring? Rubbish! (6)
I believe the answer is:
litter
This clue might be a double definition.
'batch of offspring?' is the first definition.
'litter' can be an answer for 'offspring?' (thesaurus). I am not sure about the 'batch of' bit.
'rubbish' is the second definition.
(litter is a kind of rubbish)
Can you help me to learn more?
(Other definitions for litter that I've seen before include "Animal young, stretcher and rubbish" , "little ones?" , "Sow's young" , "Family" , "Refuse - to give birth" .)
