Stay quiet, taking in speaker and this writer? (10)
I believe the answer is:
moratorium
'stay' is the definition.
(thesaurus)
'quiet taking in speaker and this writer?' is the wordplay.
'quiet' becomes 'mum' (to keep mum is to stay quiet).
'taking in' is an insertion indicator.
'speaker' becomes 'orator' (orator is a kind of speaker).
'and' is a charade indicator (letters next to each other).
'this writer?' becomes 'I' (the person writing the crossword).
'orator'+'i'='oratori'
'mum' enclosing 'oratori' is 'MORATORIUM'.
(Other definitions for moratorium that I've seen before include "Prohibition" , "Legal delay" , "Temporary halt in activity" , "agreed postponement" , "Agreed pause in activity" .)
