Inspiration for writer's books returning after long time (5)
I believe the answer is:
erato
'inspiration' is the definition.
(one of the muses in Greek mythology)
'books returning after long time' is the wordplay.
'books' becomes 'OT' (Old Testament).
'returning' shows that the letters should be reversed in order.
'after' says to put letters next to each other.
'long time' becomes 'era' (a long period of time).
'ot' back-to-front is 'to'.
'to' put after 'era' is 'ERATO'.
'for writer's' acts as a link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for erato that I've seen before include "verses she inspired" , "Who may have inspired poetry" , "Arts patron" , "poetic patroness" , "Greek muse - orate (anag)" .)
