Chap with key – a renowned African leader (7)
I believe the answer is:
mandela
'renowned african leader' is the definition.
I know nothing about this answer so I can't tell whether it can be defined by this definition.
'chap with key a' is the wordplay.
'chap' becomes 'man' (chap can mean a man).
'with' is a charade indicator (letters next to each other).
'key' becomes 'del' (del key on a keyboard).
'man'+'del'+'a'='MANDELA'
Can you help me to learn more?
(Other definitions for mandela that I've seen before include "Nelson --, South African statesman" , "Former prisoner" , "Could be Nelson" , "Nelson lengthily detained" , "Nelson --, South African politician" .)
