deep-seated
UK: ˌdiːp ˈsiːtɪd | US: ˌdip ˈsitɪd
adj. firmly established and unlikely to change (often used for beliefs, emotions, or problems)
The term "deep-seated" combines "deep," from Old English dēop (extending far down), and "seat," from Old Norse sæti (a place to sit). The metaphor suggests something firmly "placed" or rooted in a profound, inaccessible layer, like an object buried deep in the ground. Over time, it evolved to describe ingrained attitudes or issues resistant to change.
