Unthinkable, a short part for the lead (5)

Ross

I believe the answer is:

leash

'the lead' is the definition.
('leash' can be a synonym of 'lead')

'unthinkable a short part' is the wordplay.
'part' indicates the answer is hidden within the clue.
'LEASH' is hidden within 'unthinkable a short'.

'for' acts as a link.

(Other definitions for leash that I've seen before include "Rope to control dog" , "Strap for holding a dog while walking" , "Three animals" , "Rope used to restrain an animal" , "Dog lead" .)

I've seen this clue in The Guardian.
