Jog the memory about intellect (6)
I believe the answer is:
remind
'jog the memory' is the definition.
(thesaurus)
'about intellect' is the wordplay.
'about' becomes 're' (regarding).
'intellect' becomes 'mind' (mind is a kind of intellect).
're'+'mind'='REMIND'
(Other definitions for remind that I've seen before include "Jog memory, cause to think of" , "Cause someone to remember" , "Prompt; cue" , "Jog one's memory" , "Prompt, assist someone to remember" .)
