Draw saw (6)
I believe the answer is:
beheld
'draw saw' is the definition.
'beheld' can be an answer for 'saw' (I've seen this before). I am not sure about the 'draw' bit.
'draw saw' is the wordplay.
'draw' becomes 'be' (I can't justify this - if you can you should believe this answer much more).
'saw' becomes 'held' (holding is a kind of seeing).
'be'+'held'='BEHELD'
Can you help me to learn more?
(Other definitions for beheld that I've seen before include "Saw or observed in olden times" , "Laid eyes on" , "Seen" , "watched" .)
