God having succeeded thanks Jamaican devotee (5)
I believe the answer is:
rasta
'jamaican devotee' is the definition.
'rasta' can be an answer for 'devotee' (devotee of Rastafarianism). I am not sure about the 'jamaican' bit.
'god having succeeded thanks' is the wordplay.
'god' becomes 'Ra' (Egyptian god).
'having' is a charade indicator (letters next to each other).
'succeeded' becomes 's' (genealogical abbreviation).
'thanks' becomes 'ta' (UK informal version of 'thank you').
'ra'+'s'+'ta'='RASTA'
Can you help me to learn more?
(Other definitions for rasta that I've seen before include "One dreaded" , "Sectarian of Jamaican origin (colloq.)" , "Jamaican cultist" , "Believer with dreadlocks" , "religious believer" .)
