Shared bit of content egotist's mantra? (4)
I believe the answer is:
meme
'egotist's mantra?' is the definition.
The definition suggests a singular noun which matches the answer.
'shared bit of content' is the wordplay.
'shared' becomes 'm' (I can't explain this - if you can you should believe this answer much more).
'bit' becomes 'element'.
'of content' indicates the central letters (I've seen 'content' mean this).
The central letters of 'element' are 'eme'.
'm'+'eme'='MEME'
Can you help me to learn more?
(Other definitions for meme that I've seen before include "Transmitted cultural idea" , "Often trite image" , "Concept that spreads rapidly on the Internet" , "Cultural feature passed on by imitation" , "Cultural belief that assumes a life of its own" .)
