Bombs go down breaking ship apart (6)
I believe the answer is:
speeds
'bombs' is the definition.
The answer and definition can be both man-made objects as well as being plural nouns.
Perhaps you can see an association between them that I can't see?
'go down breaking ship apart' is the wordplay.
'go' becomes 'pee' (both can mean to urinate).
'down' becomes 'd'.
'breaking' indicates putting letters inside.
'ship apart' becomes 'ss' (prefix in ship names eg SS Great Britain. I am not sure about the 'apart' bit.).
'pee'+'d'='peed'
'peed' inserted inside 'ss' is 'SPEEDS'.
Can you help me to learn more?
(Other definitions for speeds that I've seen before include "Goes fast, maybe too fast" , "Rates of acceleration" , "Moves very quickly" , "Rates of movement" , "these may be in knots" .)
