Swear about getting new response (6)
I believe the answer is:
answer
'response' is the definition.
(I know that answer is a type of response)
'swear about getting new' is the wordplay.
'about' is an anagram indicator.
'getting' indicates putting letters inside.
'new' becomes 'n' (common abbreviation eg NT for New Testament).
'swear' with letters rearranged gives 'aswer'.
'aswer' placed around 'n' is 'ANSWER'.
(Other definitions for answer that I've seen before include "fit" , "Respond" , "It could give you a" , "Be satisfactory" , "Serve" .)
