Set down, record (3)
I believe the answer is:
log
This clue is a double definition.
'set down' is the first definition.
(thesaurus)
'record' is the second definition.
(logging is a kind of recording)
(Other definitions for log that I've seen before include "Enter" , "Piece of wood - record" , "fuel consumed" , "Bulky piece of wood" , "Record kept" .)
