Departs a centre on English river (6)
I believe the answer is:
danube
'river' is the definition.
(Danube is an example)
'departs a centre on english' is the wordplay.
'departs' becomes 'd' (common abbreviation e.g. train timetables).
'centre on' becomes 'nub' (I've seen this before. I am not sure about the 'on' bit.**).
'english' becomes 'e' (abbreviation).
'd'+'a'+'nub'+'e'='DANUBE'
Can you help me to learn more?
(Other definitions for danube that I've seen before include "Viennese river" , "flower" , "5 down's river" , "It's blue according to the song" , "Central European river" .)
