Respond about article before court (5)
I believe the answer is:
react
'respond' is the definition.
(I've seen this before)
'about article before court' is the wordplay.
'about' becomes 're' (regarding**).
'article' becomes 'a' (indefinite article).
'before' says to put letters next to each other.
'court' becomes 'ct'.
're'+'a'+'ct'='REACT'
(Other definitions for react that I've seen before include "Acknowledge" , "Retaliate" , "Respond to a stimulus" , "Respond emotionally" , "Take" .)
