Once more, let's get this straight (7)
I believe the answer is:
realign
'this straight' is the definition.
The definition and answer are not the same part of speech.
'once more let's' is the wordplay.
'once more' becomes 're' (prefix in words like 're-emerge' or 're-enter').
'let' becomes 'align' (I can't justify this - if you can you should give a lot more credence to this answer).
're'+'align'='REALIGN'
'get' is the link.
(Other definitions for realign that I've seen before include "Change to a different state or position" , "return to proper position" , "Change to a new position" , "Arrange again" , "Apply" .)
