Sailor and German worker get rich (8)
I believe the answer is:
abundant
'rich' is the definition.
(similar 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'
'get' acts as a link.
(Other definitions for abundant that I've seen before include "Exuberant" , "Existing in large quantities, plentiful" , "Luxuriant" , "'Copious, galore (8)'" , "Copious, plentiful" .)
