Finding where the ship is and adding up the fatalities? (4,9)
I believe the answer is:
dead reckoning
This clue could be a double definition.
'finding' is the first definition.
The answer and definition can be both acts as well as being singular nouns.
Maybe you can see an association between them that I don't see?
'where the ship is and adding up the fatalities?' is the second definition.
Although both the answer and definition are singular nouns, I can't see how they can define each other.
Can you help me to learn more?
(Other definitions for dead reckoning that I've seen before include "Estimating sea position blind" , "counting the casualties?" , "Method of estimating ship's or plane's location" , "Estimation of position at sea by reference to course steered and distance run" , "Checking losses in battle" .)
