Put away 1000 1000 1000 1 times 500 takes energy? (9)
I believe the answer is:
committed
'put away' is the definition.
(I've seen this before)
'1000 1000 1000 1 times 500 takes energy?' is the wordplay.
I cannot really understand how this works, but
'1000' could be 'm' (roman numeral) and 'm' is present in the answer.
'1' could be 'i' (Roman numeral) and 'i' is located in the answer.
'times' could be 'tt' (an abbreviation for time written twice) and 'tt' is located in the answer.
'500' could be 'd' (Roman numeral for 500) and 'd' is present in the answer.
'energy?' could be 'e' (physics symbol as in E=mc2) and 'e' is found in the answer.
This explanation may well be incorrect...
(Other definitions for committed that I've seen before include "Bound or obligated" , "put away" , "Performed an act" , "Dedicated" , "Carried out" .)
