Morphology

ascertained = ascertain (transparent) = ascertain + ed

Regular adjectival/past-participle formation from the verb 'ascertain' + '-ed' yields the meaning 'determined' directly.

Etymology

The word ascertained comes from older parts that meant 'make certain'. It joins a- with certain, which means 'sure'. So when something is ascertained, it has been 'made sure' or carefully 'found out'.
