Object in lorry leaving Edinburgh for starters (7)
I believe the answer is:
article
'object' is the definition.
'lorry leaving edinburgh for starters' is the wordplay.
'lorry' becomes 'artic' (informal term for an articulated lorry).
'for starters' indicates taking the first letters.
The first letters of 'leaving edinburgh' is 'le'.
'artic'+'le'='ARTICLE'
'in' is the link.
(Other definitions for article that I've seen before include "Maybe the" , "You might say one" , "leader" , "'The', definitely" , "Newspaper piece" .)
