Grammatical notes: As a third-conjugation verb, cadere follows the standard endings for most tenses. The present active indicative forms include cadō, cadis, cadit, cadimus, caditis, cadunt; the imperfect uses cadēbam, cadēbās, cadēbat, etc.; the perfect active is cecīdī, and other tenses are formed with the same stem. The verb also yields a number of related nouns and adjectives, such as casus, derived from the supine casum, meaning "fall," "event," or "misfortune," which in turn gives rise to several related terms in Latin and later languages.

Etymology and derivatives: Cadere itself is the core Latin verb meaning “to fall.” The noun casus (from the supine casum) expresses related notions of a fall or happening and serves as the source of related English terms through Latin and later transmission. In Latin literature, cadere appears in a range of figurative uses, describing both physical descent and unfolding events, and it participates in many compound forms and idioms that articulate states or occurrences derived from the idea of falling.
