pragurilor

Pragurile is one of the Romanian terms built on the noun prag, with pragurile being the definite plural form and used to refer to multiple thresholds or limits. In general, a prag denotes a boundary or transition point. Literally, it can mean the threshold between two spaces, such as the door of a house. Figuratively, it designates a level at which a change occurs, a condition is met, or an action is triggered.

The concept is used across diverse fields. In architecture, it refers to physical thresholds at doorways or between rooms. In psychology and sensory science, it appears in expressions like prag de detecție or prag perceptual, describing the minimal stimulus needed for perception or response. In engineering and safety disciplines, thresholds such as praguri de sensibilitate, praguri de siguranță or similar limits define operational or safety criteria. In social sciences and policy, the term is common in phrases like pragul de sărăcie or praguri de vârstă, which mark income cutoffs or legal age limits for rights and responsibilities. In data analysis and computing, praguri de tăiere or thresholding refer to cut-off values used to classify or flag data.

Usage notes: pragurile poate apare în texte academice sau tehnice oriunde se discută mai multe limite sau seturi de limite. Forma plurală poate fi folosită atât în sensul de multiple praguri, cât și în construcții care specifică apartenența acestora (de exemplu, pragurile unui sistem). Contextul determină exact sensul: literal, de arhitectură, sau figurat, ca limită operatională sau socială.
