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 defines the answer.
'service to the west indies' is the wordplay.
'service' becomes 'ser' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'to' says to put 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" .)
