Nelson laid out with injured arm (7)
I believe the answer is:
admiral
This clue might be a double definition.
'nelson' is the first definition.
Both the definition and answer are singular nouns.
Maybe there's a link between them I don't understand?
'laid out with injured arm' is the second definition.
Although both the answer and definition are singular nouns, I don't see how they can define each other.
Can you help me to learn more?
(Other definitions for admiral that I've seen before include "Brightly coloured butterfly" , "[NELSON] perhaps" , "Naval chief" , "Chief commander of fleet" , "Highest ranking naval officer" .)
