A more recommendable, faultless service to the West Indies (5)
I believe the answer is:
wiser
'a more recommendable faultless' is the definition.
I can't tell whether this definition defines the answer.
'service to the west indies' is the wordplay.
'service' becomes 'ser' (I can't justify this - if you can you should believe this answer much more).
'to' is a charade indicator (letters next to each other) (I've seen this in other clues).
'the west indies' becomes 'wi'.
'ser' put after 'wi' is 'WISER'.
Can you help me to learn more?
(Other definitions for wiser that I've seen before include "more like Charles V" , "Having learned one's lesson?" , "More sagacious" , "A little more sage" , "More knowing" .)
