Provide large numbers for queen's offspring (7)
I believe the answer is:
kittens
'provide large' is the definition.
I can't judge whether this definition defines the answer.
'numbers for queen's offspring' is the wordplay.
'numbers' becomes 'tens' (I have seen 'Cardinal numbers ' mean 'tens' so perhaps 'numbers' could also mean 'tens').
'for' is a charade indicator (letters next to each other) (I've seen this in other clues).
'queen's offspring' becomes 'kit' (I can't explain this - if you can you should believe this answer much more).
'tens' after 'kit' is 'KITTENS'.
Can you help me to learn more?
(Other definitions for kittens that I've seen before include "Young cats" , "Young felines" , "Have such pets" , "Young rabbits" , "Feline young" .)
