deep-seeded
Firmly planted within
Deep-seeded is a common reshaping of *deep-seated*, meaning firmly established or ingrained: deep-seeded prejudice, deep-seeded fears.
The substitution of "seeded" for "seated" makes intuitive sense—something planted deep takes root—but *deep-seated* remains the standard form.
Many consider deep-seeded an error.
