Massive whale damaged my big dock. No good! (4,4)
I believe the answer is:
moby dick
'massive whale' is the definition.
'moby dick' can be an answer for 'whale' (I've seen this before). I am unsure of the 'massive' bit.
'damaged my big dock no good' is the wordplay.
'damaged' indicates an anagram.
'no' is a deletion indicator.
'good' becomes 'g' (abbreviation).
'my'+'big'+'dock'='mybigdock'
'mybigdock' with 'g' removed is 'mybidock'.
'mybidock' is an anagram of 'MOBY-DICK'.
Can you help me to learn more?
(Other definitions for moby dick that I've seen before include "Herman Melville's great novel of the White Whale" , "work by American" , "Beast in book" , "Book by Herman Melville" .)
