Tell, communicate (6)
I believe the answer is:
relate
I believe this clue is a double definition.
'tell' is the first definition.
(as in to tell or relate a story)
'communicate' is the second definition.
(thesaurus)
(Other definitions for relate that I've seen before include "Show a connection between (things)" , "Connect in Tralee" , "Tell; a counselling service" , "Give a report or show a connection" , "Make a logical or causal connection" .)
