Selfish endeavour say to put up inscription on tomb (3,4)
I believe the answer is:
ego trip
'selfish endeavour' is the definition.
The answer and definition can be both acts as well as being singular nouns.
Maybe you can see a link between them that I don't see?
'say to put up inscription on tomb' is the wordplay.
'say' becomes 'eg'.
'put up' shows that the letters should be reversed in order.
'inscription on tomb' becomes 'rip' (I've seen this before).
'to' reversed gives 'ot'.
'eg'+'ot'+'rip'='EGO TRIP'
Can you help me to learn more?
(Other definitions for ego trip that I've seen before include "action boosting self-esteem" , "Self-indulgent activity" , "Experience enjoyed by the conceited" , "Something done to boost self-importance" , "Act done to increase one's self-importance" .)
