Did you know?
Hidebound has its origins in agriculture. The adjective, which appeared in English in the early 17th century, originally described cattle whose skin, due to illness or poor feeding, clung to the skeleton and could not be pinched, loosened, or worked with the fingers (the adjective followed an earlier noun form referring to this condition). Hidebound was applied to humans too, to describe people afflicted with tight skin. Figurative use quickly followed, first with a meaning of “stingy” or “miserly.” That sense has since fallen out of use, but a second figurative usage, describing people who are rigid or unyielding in their actions or beliefs, lives on in our language today.
