Sailors trick the German one doing runner (9)
I believe the answer is:
absconder
'one doing runner' is the definition.
'absconder' can be an answer for 'runner' (I've seen this before). I'm unsure of the 'one doing' bit.
'sailors trick the german' is the wordplay.
'sailors' becomes 'abs' (AB is short for able seaman).
'trick' becomes 'con' (I've seen this before).
'the german' becomes 'der' ('the' in German).
'abs'+'con'+'der'='ABSCONDER'
Can you help me to learn more?
(Other definitions for absconder that I've seen before include "Runaway" , "runner" , "Arrest evader" .)
