No ordinary seaman (7)
I believe the answer is:
admiral
This might be a double definition.
'no ordinary' is the first definition.
The answer and definition can be both people as well as being singular nouns.
Perhaps there's a link between them I don't understand?
'seaman' is the second definition.

Perhaps there's an association between them I don't understand?
Can you help me to learn more?
(Other definitions for admiral that I've seen before include "Highest ranking naval officer" , "Chief commander of fleet" , "Naval officer of high rank" , "Supreme naval commander" , "Naval chief" .)
