False name as used in Dakar (5)
I believe the answer is:
alias
'false name' is the definition.
(synonyms)
'as used in dakar' is the wordplay.
I cannot really see how this works, but
'as' is found in the answer.
The remaining letters 'ali' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for alias that I've seen before include "Handle that isn't genuine" , "Alternative identity" , "another name" , "Otherwise known as" , "Otherwise called" .)
