Scores of seamen? (7)
I believe the answer is:
ratings
This clue might be a double definition.
'scores' is the first definition.
The answer and definition can be both acts as well as being plural nouns.
Maybe they are linked in a way I don't understand?
'seamen?' is the second definition.
(British term for a naval enlisted man)
'of' acts as a link.
Can you help me to learn more?
(Other definitions for ratings that I've seen before include "Staring at classifications" , "they matter to broadcasters" , "Programme audience size; sailors" , "Members of crew" , "chased by TV companies?" .)
