Give different positions to the row at the back
I believe the answer is:
rearrange
'give different positions to' is the definition.
I can't judge whether this defines the answer.
'row at the back' is the wordplay.
'row' becomes 'range' (I've seen this in other clues).
'at' says to put letters next to each other (I've seen this in other clues).
'the back' becomes 'rear' ('rear' can be a synonym of 'back').
'range' put after 'rear' is 'REARRANGE'.
'the' acts as a link.
Can you help me to learn more?
(Other definitions for rearrange that I've seen before include "Put new structure" , "Move round" , "Move to new positions" , "Sort" , "Tidy up" .)
