Opens novel over the weekend it is said (6)
I believe the answer is:
spoken
'said' is the definition.
(thesaurus)
'opens novel over the weekend' is the wordplay.
'novel' indicates anagramming the letters.
'over' means one lot of letters goes inside another.
'the weekend' becomes 'k' (I've seen this in other clues).
'opens' anagrammed gives 'spoen'.
'spoen' going around 'k' is 'SPOKEN'.
'it is' is the link.
(Other definitions for spoken that I've seen before include "Verbalised" , "Declared" , "Said" , "Uttered through the medium of speech" , "Verbal" .)
