Give a new form of food (4)
I believe the answer is:
wean
'form of food' is the definition.
Although both the answer and definition are verbs in their base form, I cannot understand how they can define each other.
'give a new' is the wordplay.
'give' is an anagram indicator (I've seen 'giving' mean this (the letters give the letters for another word)).
'a'+'new'='anew'
'anew' with letters rearranged gives 'WEAN'.
Can you help me to learn more?
(Other definitions for wean that I've seen before include "Abandon" , "Gradually deprive the young of its mother's milk" , "Accustom to abstain from a former habit" , "Introduce to solid food" , "Accustom baby to take food instead of milk" .)
