Leader of tour on nameless African river’s a dynamic individual (5)
I believe the answer is:
tiger
'a dynamic individual' is the definition.
The definition and answer can be both people as well as being singular nouns.
Maybe you can see an association between them that I don't see?
'leader of tour on nameless african river's' is the wordplay.
'leader of tour on nameless african' becomes 'tige' (I can't justify this - if you can you should believe this answer much more).
'river' becomes 'r' (abbreviation for river).
'tige'+'r'='TIGER'
Can you help me to learn more?
(Other definitions for tiger that I've seen before include "Formidable competitor" , "Fierce Bengal beast" , "fierce animal" , "Beast as Shere Khan" , "- - Woods (golf)" .)
