Protein-rich food for one struggling with weight? (3,5)
I believe the answer is:
egg white
'weight?' is the definition.
Although both the answer and definition are singular nouns, I can't understand how they can define each other.
'protein-rich food for one struggling with' is the wordplay.
'protein' becomes 'egg' (source of protein).
'rich food' becomes 'e' (E is an example. I am not sure about the 'rich' bit.).
'for' is a charade indicator (letters next to each other) (I've seen this in other clues).
'one struggling' is an anagram indicator (the letters struggle or wriggle into a new form).
'with' anagrammed gives 'whit'.
'e' put after 'whit' is 'white'.
'egg'+'white'='EGG-WHITE'
Can you help me to learn more?
(Other definitions for egg white that I've seen before include "Meringue ingredient" , "Albumen, not the yolk" , "Cake ingredient" , "Albumen, transparent ovum content" .)
