Old tales rehashed (5)
I believe the answer is:
stale
'old' is the definition.
(similar in meaning)
'tales rehashed' is the wordplay.
'rehashed' is an anagram indicator (I've seen 'rehash' mean this).
'tales' with letters rearranged gives 'STALE'.
(Other definitions for stale that I've seen before include "Musty or hackneyed" , "no longer bearing interest?" , "Old; musty" , "Boring" , "past the sell-by date" .)
