posteriorní

Posteriorní is a Czech adjective meaning relating to the back or rear, or situated toward the rear. It is the direct Czech equivalent of the English term posterior and is used in formal and technical language. The word forms a contrast with anteriorní, which denotes the front or forward part.

In anatomy, posteriorní describes the back portion of a structure in the standard anatomical sense. In humans, it refers to the back side; in four-legged animals it points toward the hind end. It is commonly used in phrases such as posteriorní část (posterior part) or posteriorní povrch (posterior surface) of a bone or organ.

In science and related fields, posteriorní appears in contexts such as Bayesian statistics, where posteriorní rozdělení denotes the posterior distribution of parameters after observing data, and posteriorní pravděpodobnost denotes the posterior probability of a hypothesis. In philosophy and everyday scholarly language, the Latin expression a posteriori is used to refer to knowledge derived from experience; the Czech term may appear in translated or technical texts as a posteriori, while posteriorní serves as the adjectival form describing related concepts.

Etymology and usage notes: posteriorní derives from Latin posterior, with the Czech suffix -ní to form an adjective. In everyday Czech, simpler terms like zadní are often used, but posteriorní remains common in precise, technical writing across medicine, biology, and related disciplines.
