A large scrap seen in motor programme (8)
I believe the answer is:
calendar
'programme' is the definition.
(thesaurus)
'a large scrap seen in motor' is the wordplay.
'large' becomes 'l'.
'scrap' becomes 'end' ('end' can be a synonym of 'scrap'**).
'seen in' means one lot of letters goes inside another.
'motor' becomes 'car' (I've seen this before).
'a'+'l'+'end'='alend'
'alend' put within 'car' is 'CALENDAR'.
(Other definitions for calendar that I've seen before include "Table of the days of a year" , "Schedule" , "Chart of times" , "Year chart" , "Chart showing seasons etc" .)
