Jeer King John? (4)
I believe the answer is:
book
'john?' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe there's a link between them I don't understand?
'jeer king' is the wordplay.
'jeer' becomes 'boo' (I've seen this before).
'king' becomes 'k' (abbreviation for king in chess).
'boo'+'k'='BOOK'
Can you help me to learn more?
(Other definitions for book that I've seen before include "Hardback, say" , "Rebecca or Emma maybe" , "Show yellow card" , "Strict rules" , "Reserve - publication" .)
