Start to go and file in comprehension (5)

Ross

I believe the answer is:

grasp

'comprehension' is the definition.
(I've seen this before)

'start to go and file' is the wordplay.
'start to' indicates taking the first letters.
'and' is a charade indicator (letters next to each other).
'file' becomes 'rasp' (rasp is a kind of file).
The first letter of 'go' is 'g'.
'g'+'rasp'='GRASP'

'in' is the link.

(Other definitions for grasp that I've seen before include "Get hold of firmly" , "Seize - comprehend" , "Catch on" , "Hold - understanding" , "Lay hold of" .)

I've seen this clue in the Sydney Morning Herald.
