Tending to disillusion; revealing falseness or creating disappointment about false beliefs.
From disillusion + -ive (forming adjectives meaning 'tending to'). The '-ive' suffix comes from Latin '-ivus,' creating adjectives from verb stems.
This is a particularly elegant word because '-ive' suggests a quality or tendency rather than an action—a 'disillusive' experience doesn't just disappoint you, it has a nature or character that includes revealing truth, which is subtly different from merely 'disillusioning.'
