impinge

'touch' is the definition.
(thesaurus)

'zulu warriors coming to strange end' is the wordplay.
'zulu warriors' becomes 'impi' (I've seen this before).
'coming to' becomes 'ng' (I can't justify this - if you can you should believe this answer much more).
'end' suggests the final letters.
The final letter of 'strange' is 'e'.
'impi'+'ng'+'e'='IMPINGE'

'on' acts as a link.

Can you help me to learn more?

(Other definitions for impinge that I've seen before include "Strike - make an impression (on)" , "Have an effect (upon)" , "Encroach - strike" , "Encroach on the pig in me" , "Encroach, have effect, on" .)
