Jot down — LP? (6)
I believe the answer is:
record
I believe this clue is a double definition.
'jot down' is the first definition.
(thesaurus)
'lp?' is the second definition.
(I know that lp is a standard UNIX utility)
(Other definitions for record that I've seen before include "State officially; disc" , "It may get broken" , "Highest achievement" , "A minute" , "The finest achievement" .)
