Such charges can be profoundly disturbing at sea (5)
I believe the answer is:
depth
This clue could be a double definition.
'such charges can' is the first definition.
Although both the answer and definition are singular nouns, I can't see how one could define the other.
'profoundly disturbing at sea' is the second definition.
Although both the answer and definition are singular nouns, I can't understand how one could define the other.
'be' is the link.
Can you help me to learn more?
(Other definitions for depth that I've seen before include "Deepness" , "Distance from top down as in water" , "Distance downwards" , "sometimes leading to charge for sailors at war?" , "Measure" .)
