Something funny placed on tomb (3,3)
I believe the answer is:
bon mot
'something funny' is the definition.
I can't judge whether this definition defines the answer.
'placed on tomb' is the wordplay.
'placed' indicates anagramming the letters (placing the letters).
'on'+'tomb'='ontomb'
'ontomb' with letters rearranged gives 'BON MOT'.
Can you help me to learn more?
(Other definitions for bon mot that I've seen before include "Appropriate word or expression - in France" , "The right or apposite word - in France" , "Apt or witty remark - in France" , "Witticism" , "term of French, it's appropriate to say" .)
