Intellectuals, for example, with good leaders (8)
I believe the answer is:
eggheads
'intellectuals' is the definition.
(I know this)
'example with good leaders' is the wordplay.
'example' becomes 'eg' (short for 'exempli gratia', 'for example' in Latin).
'with' says to put letters next to each other.
'good' becomes 'g' (abbreviation).
'leaders' becomes 'heads' (head is a kind of leader).
'eg'+'g'+'heads'='EGGHEADS'
'for' is the link.
(Other definitions for eggheads that I've seen before include "Slang intellectuals with lofty domes" , "Slangy intellectuals with lofty domes" , "Boffins" , "Intellectuals (colloq.)" , "Intellectuals with oval brains?" .)
