Ocean book doesn't end with new twitch (8)
I believe the answer is:
atlantic
'ocean' is the definition.
(I know that Atlantic is a ocean)
'book doesn't end with new twitch' is the wordplay.
I cannot quite see how this works, but
'book' could be 'nt' (New Testament) and 'nt' is found within the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for atlantic that I've seen before include "Latin cat found, strangely, in the ocean" , "Second-largest ocean" , "One of earth's oceans" , "Tilt a can at the ocean" , "UK's nearest ocean" .)
