transitorius

Transitorius is a Latin adjective meaning temporary, fleeting, or transitional. It is derived from transitus, meaning a going across or passage, with the suffix -orius, giving the sense of belonging to a transition or to a passing state. In classical and medieval Latin, transitorius described conditions or qualities that are not permanent, often in contrast to more lasting features.

In scholarly Latin, the term appears in medical, botanical, and zoological contexts to indicate phenomena that are temporary or intermediate stages. It can describe a disease condition that is transient, a developmental stage that represents a transition between forms, or an anatomical feature observed only under certain conditions. Although not a fixed technical term in taxonomy, it may be employed by authors to designate transitional forms or processes that shift from one state to another, with the exact nuance dependent on the author and context.

Modern usage of the word survives primarily in historical Latin texts, translations, and scholarly discussions of Latin terminology. In the Romance languages, cognates exist such as transitorio in Spanish and Italian, and transitório in Portuguese. In English, transitory is the direct descendant for general use, while transitorius appears mainly in scholarly Latin quotations or glosses to indicate a transitional or temporary character.
