Loan a vehicle, covering timetable (8)
I believe the answer is:
calendar
'timetable' is the definition.
(I've seen this before)
'loan a vehicle covering' is the wordplay.
'loan' becomes 'lend' (synonyms).
'vehicle' becomes 'car' (car is a kind of vehicle).
'covering' indicates putting letters inside.
'lend'+'a'='lenda'
'lenda' put inside 'car' is 'CALENDAR'.
(Other definitions for calendar that I've seen before include "Table of months and days" , "Laden car (anag)" , "Diary" , "that's dated" , "Almanac" .)
