All taken apart (5)
I believe the answer is:
every
'all' is the definition.
(similar in meaning)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for every that I've seen before include "As much as possible" , "All, taken separately" , "All possible; the utmost" , "Each single (item)" , "'God bless us - - one !'" .)
