Rich sailor and German worker (8)
I believe the answer is:
abundant
'rich' is the definition.
(associated in meaning)
'sailor and german worker' is the wordplay.
'sailor' becomes 'ab' (abbreviation for able seaman).
'and german' becomes 'und' ('and' in German).
'worker' becomes 'ant' (worker is a type of ant).
'ab'+'und'+'ant'='ABUNDANT'
(Other definitions for abundant that I've seen before include "Plentiful, ample" , "Copious, profuse" , "Existing in large amounts" , "In plentiful supply" , "well-provided" .)
