Rich sailor and German soldier (8)
I believe the answer is:
abundant
'rich' is the definition.
(similar in meaning)
'sailor and german soldier' is the wordplay.
'sailor' becomes 'ab' (abbreviation for able seaman).
'and german' becomes 'und' ('and' in German).
'soldier' becomes 'ant' (soldier is a type of ant).
'ab'+'und'+'ant'='ABUNDANT'
(Other definitions for abundant that I've seen before include "Guardian spirit" , "Plentiful, profuse" , "Copious, profuse" , "well-provided" , "Exuberant" .)
