Start travelling to Nigeria (9)
I believe the answer is:
originate
'start' is the definition.
(I know that originate is a more specific form of the action start)
'travelling to nigeria' is the wordplay.
'travelling' is an anagram indicator.
'to'+'nigeria'='tonigeria'
'tonigeria' is an anagram of 'ORIGINATE'.
(Other definitions for originate that I've seen before include "Found" , "Set up" , "Invent" , "From kick off" , "Come into existence" .)
