Figure with cake and tea getting biscuit at the back (3,5)
I believe the answer is:
bar chart
'figure' is the definition.
The answer and definition can be both related to communication as well as being singular nouns.
Perhaps you can see an association between them that I can't see?
'cake and tea getting biscuit at the back' is the wordplay.
'cake' becomes 'bar' (synonyms).
'and' is a charade indicator (letters next to each other).
'tea getting' becomes 'char' (I can't justify this - if you can you should believe this answer much more).
'at the back' suggests the final letters.
The final letter of 'biscuit' is 't'.
'bar'+'char'+'t'='BAR CHART'
'with' acts as a link.
Can you help me to learn more?
(Other definitions for bar chart that I've seen before include "Diagram showing figures" , "graph" , "display of information" , "Table" .)
