Head of catering rips out a snack (5)
I believe the answer is:
crisp
'a snack' is the definition.
The definition and answer can be both things that one consumes for nourishment as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'head of catering rips out' is the wordplay.
'head of' says to take the initial letters.
'out' indicates an anagram (out can mean wrong or inaccurate).
The initial letter of 'catering' is 'c'.
'rips' with letters rearranged gives 'risp'.
'c'+'risp'='CRISP'
Can you help me to learn more?
(Other definitions for crisp that I've seen before include "Firm - sharp - brittle" , "Tender and brittle" , "Firm ,dry, brittle" , "fried food" , "food in packet" .)
