Amissus
Amissus is a Latin adjective meaning "lost," "gone," "missing," or "forgone." It is the perfect passive participle of the verb amittō, which means "to lose," "to let go," "to send away," or "to dismiss."
As an adjective, amissus is a first/second declension adjective, and thus follows the standard declension patterns for adjectives of this type. Its forms will vary depending on the gender, number, and case of the noun it modifies.
In legal or formal contexts, amissus can refer to something that has been legally forfeited or deprived. The concept of being "lost" can also extend metaphorically to a loss of hope or a moral lapse.
