"Beray" combines "be-" with "ray" (to soil, defile, of uncertain origin), creating a verb meaning to make filthy or foul. The term appears in contexts both literal (garments berayed with mud) and figurative (honor berayed by scandal). Medieval and Renaissance writers used it when describing degradation, pollution, or moral staining. The word's harshness suited descriptions of disgrace and corruption, whether physical or spiritual. Poets valued its compact expression of defilement, which could work literally in narratives of hardship (travelers berayed by weather) or metaphorically in explorations of sin and shame. Its archaic quality lent force to denunciations and lamentations where defilement required strong expression. The term's relative obscurity gave it learned associations appropriate to formal invective or tragic description of fallen states.

Beray appears most prominently in medieval and Renaissance contexts describing moral or physical pollution. Chaucer and his contemporaries use it for both literal soiling (from travel, battle) and figurative defilement (sin, shame). The term's harshness suits invective and moral condemnation. Etymology combines "be-" (thoroughly) with "ray" (to soil), related to "befoul" but more visceral. Often appears in scenes of degradation, humiliation, or moral fall. Related to "defile" and "besmirch" but more concrete and physical. Essential for analyzing imagery of pollution, sin-as-stain metaphors, or the physical manifestations of moral corruption. The term's obsolescence reflects changing metaphors for moral states, shifting from physical contamination to psychological models.
