Notice star left Nelson? (7)
I believe the answer is:
admiral
'nelson?' is the definition.
Both the definition and answer are singular nouns.
Perhaps they are linked in a way I don't understand?
'notice star left' is the wordplay.
'notice' becomes 'ad' (short for advert).
'star' becomes 'mira' (star in the constellation Cetus).
'left' becomes 'l' (common abbreviation).
'ad'+'mira'+'l'='ADMIRAL'
Can you help me to learn more?
(Other definitions for admiral that I've seen before include "Highest ranking naval officer" , "Blake, for one" , "Navy rank" , "Supreme naval commander" , "Eg, Nelson" .)
