Morphology

simultaneous = simultane + ous

The adjective contains the combining form 'simultane-' (not a standalone English word) plus the productive suffix '-ous', so an average B1 learner cannot derive the meaning from familiar English base words.

Etymology

Simultaneous comes from the Latin root simul, which means 'at the same time' or 'together', and the same root is used in words like simulcast that describe things happening 'together'. So, something simultaneous happens exactly at the same time as something else.
