Morphology

unobserved = observed (transparent) = un + observe + ed

The negative prefix 'un-' attaches to the participial/adjectival 'observed' to give the simple meaning 'not seen', which is directly inferable.

Etymology

The word unobserved is made from un- meaning 'not' and observe meaning 'to watch' or 'see'. So if something is unobserved, it is 'not watched' or not noticed by anyone, which explains its modern meaning.
