Having had the van watched, had anticipated it (8)
I believe the answer is:
foreseen
'having had the van' is the definition.
I can't judge whether this defines the answer.
'watched had anticipated it' is the wordplay.
I cannot quite understand how this works, but
'watched' could be 'seen' (I've seen this in another clue) and 'seen' is located in the answer.
'it' could be 'e' ('e' can mean 'electronic' which is similar to 'IT') and 'e' is found in the answer.
The remaining letters 'for' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for foreseen that I've seen before include "No surprise" , "Predicted" , "Anticipated" , "Envisaged" , "Expected" .)
