Buffalo seen here after antelope (5)
I believe the answer is:
nyala
'antelope' is the definition.
(nyala is a kind of antelope)
'buffalo seen here after' is the wordplay.
I cannot quite understand how this works, but
'after' could be 'ala' ('a la' - 'in the style of ' or 'after' in French) and 'ala' is found within the answer.
The remaining letters 'ny' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for nyala that I've seen before include "Spiral-horned antelope" , "South African resident" , "beast" , "South African antelope - Sudanese city" , "crested antelope" .)
