Intel about cove (5)
I believe the answer is:
inlet
'cove' is the definition.
(synonyms)
'intel about' is the wordplay.
'about' is an anagram indicator.
'intel' with letters rearranged gives 'INLET'.
(Other definitions for inlet that I've seen before include "Entry port" , "Small arm of the sea" , "Opening through which fluid can pass" , "Bay, cove" , "Arm off a larger body of water between headlands" .)
