Several submarine operators (6)
I believe the answer is:
divers
This clue might be a double definition.
'several' is the first definition.
(I've seen this in another clue)
'submarine operators' is the second definition.
The answer and definition can be both people as well as being plural nouns.
Maybe there's a link between them I don't understand?
Can you help me to learn more?
(Other definitions for divers that I've seen before include "Many and different" , "seabirds" , "Plungers" , "Underwater, they are many and various" , "Various for underwater workers?" .)
