Tell about strange tale (6)
I believe the answer is:
relate
'tell' is the definition.
(relating is a kind of telling)
'about strange tale' is the wordplay.
'about' becomes 're' (regarding**).
'strange' indicates an anagram.
'tale' with letters rearranged gives 'late'.
're'+'late'='RELATE'
(Other definitions for relate that I've seen before include "Give account of (story)" , "Narrate or associate" , "Do well; wave about" , "Marriage Guidance - report" , "Tell (a story)" .)
