Journey east accompanied by the German writer (6)
I believe the answer is:
goethe
'german writer' is the definition.
(johann wolfgang von goethe)
'journey east accompanied by the' is the wordplay.
'journey' becomes 'go' (I've seen this in other clues).
'east' becomes 'e' (synonyms).
'accompanied by' is a charade indicator (letters next to each other).
'go'+'e'+'the'='GOETHE'
(Other definitions for goethe that I've seen before include "German playwright and poet" , "German author (Faust)" , "German writer, b 1749" , "German poet, d. 1832" , "Poet's" .)
