Please record “thank you” at home (9)
I believe the answer is:
entertain
'please' is the definition.
(thesaurus)
'record thank you at home' is the wordplay.
'record' becomes 'enter' ('enter' can be a synonym of 'record').
'thank you' becomes 'ta'.
'at home' becomes 'in' ('in' can be similar in meaning to 'at home').
'enter'+'ta'+'in'='ENTERTAIN'
(Other definitions for entertain that I've seen before include "Play host to" , "Amuse; host" , "Act as host" , "Amuse, divert" , "Think about" .)
