For example, chips in "I won't be quiet!" (4)
I believe the answer is:
nosh
'for example chips' is the definition.
I can't judge whether this defines the answer.
'i won't be quiet' is the wordplay.
'i won't' becomes 'no' (refusal).
'be quiet' becomes 'sh' (both are said to tell someone to stop speaking).
'no'+'sh'='NOSH'
'in' acts as a link.
Can you help me to learn more?
(Other definitions for nosh that I've seen before include "Slangy food or meal" , "Food - eat greedily" , "(Eat) a snack" , "Food (coll)" , "A slang meal" .)
