Suppose it to be the superstructure, myself (7)
I believe the answer is:
presume
'suppose' is the definition.
(I know that suppose is a more specific form of presume)
'it to be the superstructure myself' is the wordplay.
I cannot really understand how this works, but
'it' could be 'e' ('e' can mean 'electronic' which is similar to 'IT') and 'e' is found in the answer.
'myself' could be 'me' and 'me' is located in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for presume that I've seen before include "Surmise" , "Supreme (anag)" , "Suppose without proof" , "Believe" , "Suppose; take liberties" .)
