Snack that’s easily dropped (3,6)
I believe the answer is:
hot potato
'snack' is the definition.
Although both the answer and definition are singular nouns, I don't see how they can define each other.
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for hot potato that I've seen before include "Topical, dangerous, issue" , "controversial question" , "tricky case" , "An awkward subject" , "Controversial and awkward issue" .)
