Morphology

endogenous = endo + gen + ous

Formed from bound scientific combining forms ('endo-' + 'gen' + '-ous'); the meaning 'originating from within' is recoverable by learners familiar with scientific prefixes but not by average B1 learners, so it is only semi-transparent.

Etymology

Endogenous comes from the Greek parts endo- meaning 'within' and -genous meaning 'born' or 'produced', the same root as in generate. So endogenous describes something that starts or is made 'within' a body or system, not from outside.
