A famous explorer or a cool MP perhaps (5,4)
I believe the answer is:
marco polo
'a famous explorer' is the definition.
'marco polo' can be an answer for 'explorer' (13th-century explorer). I'm not certain of the 'a famous' bit.
'or a cool mp perhaps' is the wordplay.
'perhaps' indicates an anagram.
'or'+'a'+'cool'+'mp'='oracoolmp'
'oracoolmp' anagrammed gives 'MARCO POLO'.
Can you help me to learn more?
(Other definitions for marco polo that I've seen before include "Adventurous traveller" , "Great Venetian explorer of China and Asia in 14th century" , "European traveller" , "Merchant of Venice" , "Venetian travel writer, who may (or may not) have served Kublai Khan, d. 1324" .)
