It appears in newspaper popular with German right (7)
I believe the answer is:
fitting
'right' is the definition.
(thesaurus)
'it appears in newspaper popular with german' is the wordplay.
'appears in' indicates putting letters inside.
'newspaper' becomes 'ft'.
'popular' becomes 'in'.
'with' is a charade indicator (letters next to each other).
'german' becomes 'g' (abbreviation).
'it' going into 'ft' is 'fitt'.
'fitt'+'in'+'g'='FITTING'
(Other definitions for fitting that I've seen before include "Appropriate, proper" , "Suitable, proper" , "Apt" , "Seemly" , "reason for appointment with tailor" .)
