Wipe out has nothing but started with a good education (10)
I believe the answer is:
obliterate
'wipe out' is the definition.
(I know that wipe out can be written as obliterate)
'nothing but started with a good education' is the wordplay.
'nothing' becomes 'O' (looks like zero - 0).
'started with' suggests taking the first letters (I've seen 'start with' mean this).
'a good education' becomes 'literate' (I can't explain this - if you can you should believe this answer much more).
The initial letter of 'but' is 'b'.
'o'+'b'+'literate'='OBLITERATE'
'has' is the link.
Can you help me to learn more?
(Other definitions for obliterate that I've seen before include "Eliminate" , "use eraser" , "Erase" , "Put an end to" , "Destroy all traces" .)
