Some Inca blessings in telegram (5)
I believe the answer is:
cable
'telegram' is the definition.
(cable is a kind of telegram)
'some inca blessings in' is the wordplay.
'some' says the answer is hidden in the clue (some of the parts of the word are used).
'CABLE' is hidden in the letters of 'inca blessings in'.
(Other definitions for cable that I've seen before include "Telegraph" , "Strong thick rope made of twisted hemp or steel wire" , "Satellite alternative?" , "Hawser, wire" , "Strong suspension bridge made of wire" .)
