Fearless traveller in current books and papers (8)
I believe the answer is:
intrepid
'fearless' is the definition.
(synonyms)
'traveller in current books and papers' is the wordplay.
'traveller' becomes 'rep' (travel company worker).
'in' indicates putting letters inside.
'current books' becomes 'int' (I can't explain this - if you can you should give a lot more credence to this answer).
'and' says to put letters next to each other.
'papers' becomes 'ID' (identifying documents are one's 'papers').
'int'+'id'='intid'
'rep' put inside 'intid' is 'INTREPID'.
Can you help me to learn more?
(Other definitions for intrepid that I've seen before include "Brave and fearless" , "Unfearing" , "Undaunted" , "Fearlessly adventurous" , "Audacious" .)
