Attendee at meeting developing career, full of pep (8)
I believe the answer is:
racegoer
'attendee at' is the definition.
I can't tell whether this defines the answer.
'developing career full of pep' is the wordplay.
'developing' indicates anagramming the letters (letters developed into a new form).
'full of' means one lot of letters goes inside another.
'pep' becomes 'go' (both can mean energy or vitality).
'career' with letters rearranged gives 'raceer'.
'raceer' enclosing 'go' is 'RACEGOER'.
'meeting' acts as a link.
Can you help me to learn more?
(Other definitions for racegoer that I've seen before include "Attendee at, eg, Epsom" , "Regular attender at, eg, Aintree or Epsom" , "visitor to Ascot?" , "for speculative investments?" , "Frequenter of 51 [ASCOT]" .)
