Feed young awful clues about kitten's head (6)
I believe the answer is:
suckle
'feed young' is the definition.
'suckle' can be an answer for 'feed' (thesaurus). I am not certain of the 'young' bit.
'awful clues about kitten's head' is the wordplay.
'awful' indicates anagramming the letters.
'about' means one lot of letters goes inside another.
'head' says to take the initial letters.
The first letter of 'kittens' is 'k'.
'clues' is an anagram of 'sucle'.
'sucle' enclosing 'k' is 'SUCKLE'.
Can you help me to learn more?
(Other definitions for suckle that I've seen before include "Feed (baby) from breast" , "Feed from a teat" , "Nurse" , "Nurture" , "Breastfeed" .)
