King with a bomb brought about end of battle? Observe again (2-7)
I believe the answer is:
re-examine
'observe again' is the definition.
I can't tell whether this defines the answer.
'king with a bomb brought about end of battle?' is the wordplay.
'king' becomes 'R' (abbreviation of Latin rex).
'with' means one lot of letters go next to another.
'a bomb' becomes 'examine' (I can't explain this - if you can you should give a lot more credence to this answer).
'brought about' indicates putting letters inside.
'end of' says to take the final letters.
The final letter of 'battle' is 'e'.
'examine' enclosing 'e' is 'eexamine'.
'r'+'eexamine'='RE-EXAMINE'
Can you help me to learn more?
(Other definitions for re-examine that I've seen before include "Look at again" , "Study further" , "Investigate again" .)
