Minute Cryptic

Our definition here is 'Ordinary', and our answer will be another word for that.

This clue's indicators are 'guy from', 'to assassinate', and 'inaugural'. One of these is a deletion indicator guiding us to remove some fodder from other fodder. The other two are kinds of selection indicator. 'inaugural' is a straightforward indicator, pointing out the position of one or more letters to select. 'guy from', on the other hand, doesn't point out position but meaning - we're looking at working with a guy from our neighbouring fodder.

This clue's fodder is 'Istanbul', 'dared', and 'emperor'. We'll use these letters (or some of them) to construct our answer, as guided by the clue's indicator(s). Extra hint: you could also consider 'guy' to be part of the fodder (it's line ball whether we should describe it as fodder or indicator).
