Ambitious professional rushes round island, given time (9)
I believe the answer is:
careerist
'ambitious professional' is the definition.
'careerist' can be an answer for 'professional' (careerist is a kind of professional). I am unsure of the 'ambitious' bit.
'rushes round island given time' is the wordplay.
'rushes' becomes 'careers' (I've seen this before).
'round' indicates putting letters inside.
'island' becomes 'i' (geographical abbreviation).
'given' is a charade indicator (letters next to each other).
'time' becomes 't' (abbreviation).
'careers' placed around 'i' is 'careeris'.
'careeris'+'t'='CAREERIST'
Can you help me to learn more?
(Other definitions for careerist that I've seen before include "he wants to get on" , "Maybe workaholic" , "Ambitious person" , "Ambitious type" , "Ambitious worker" .)
