Arrange a sentence, by the sound of it (5)
I believe the answer is:
align
'arrange' is the definition.
(thesaurus)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for align that I've seen before include "Arrange in a row" , "Bring into agreement" , "Regulate, arrange in line" , "Bring into correct relation" , "Make (things) fit together" .)
