Painter from German city one ignored (5)
I believe the answer is:
munch
'painter' is the definition.
(Edvard Munch)
'german city one ignored' is the wordplay.
'german city' becomes 'munich' (city in Germany).
'one' becomes 'I' (Roman numeral).
'ignored' indicates named letters should be taken away.
'munich' with 'i' removed is 'MUNCH'.
'from' acts as a link.
(Other definitions for munch that I've seen before include "Norwegian painter" , "Chew steadily - "Scream" artist" , "who's popular in the gallery?" , "Chomp" , "Edvard -, Norwegian artist (The Scream)" .)
