the compound "stiff-necked" is a calque, or literal translation, of a hebrew idiom found in biblical texts, describing a stubborn ox that refuses to turn its head when guided. the old english elements "stif" (rigid) and "hnecca" (neck) were combined with the adjectival suffix "-ed" to create a vivid metaphor for obstinacy. this imagery passed directly into english via early bible translations, carrying the sense of an unyielding, haughty disposition. over time, it evolved from a specific scriptural term into a more general descriptor for arrogant inflexibility.

Structure: stiff (rigid) + neck (body part) + ed (adjective suffix) - stiff: from old english stif meaning "rigid, inflexible"; germanic origin. - neck: from old english hnecca meaning "the nape, back of the neck"; germanic origin. - ed: a suffix forming adjectives from nouns or other adjectives, indicating possession of a quality.
