Enduring stars in stage terms? (7)
I believe the answer is:
legends
'enduring stars' is the definition.
(legend can mean a famous or iconic person)
'stage terms?' is the wordplay.
'stage' becomes 'leg' (a leg is a stage of a competition).
'terms?' becomes 'ends' (term can mean the end of something).
'leg'+'ends'='LEGENDS'
'in' acts as a link.
(Other definitions for legends that I've seen before include "Myths or inscriptions" , "Myths, fables" , "Old tales" , "Heroes" , "Stories handed down from the past" .)
