Which Spelling Is Correct?
The correct expression is deep-seated. It works as an adjective. It describes something that is firmly fixed, strongly held, or not easy to remove.

Best Meaning in Plain English
A deep-seated feeling, idea, or habit has been there for a long time and does not change easily.

Literal and Figurative Meaning
Deep-seated can also mean located far below the surface. Merriam-Webster gives two senses: situated far below the surface and firmly established.Source-3✅
In everyday writing, the figurative meaning is more common: a feeling, view, or condition is so settled that it feels deep inside someone or something.
Why Deep-Seeded Looks Tempting
Deep-seeded looks believable because seeds can be planted deep in soil. That image makes sense in your head, so the spelling can slip into writing.
The phrase is not built from the idea of a seed, though. It is built from seated, meaning something is set, placed, or fixed deeply.
Memory clue: If the meaning is “firmly set,” choose deep-seated. If you are literally talking about seeds planted deep in soil, deep-seeded could describe that literal idea, but it is not the standard phrase for beliefs, feelings, habits, or problems.
Pronunciation and Hyphen
Deep-seated is pronounced like deep SEE-tid. Oxford Learner’s Dictionaries shows the pronunciation as /ˌdiːp ˈsiːtɪd/.Source-4✅
The hyphen is normal because deep-seated is a compound adjective. It usually comes before a noun.
- ✓ Correct a deep-seated habit
- ✓ Correct a deep-seated belief
- ✓ Correct a deep-seated interest
Without the hyphen, deep seated may still be understood, but the standard dictionary form is deep-seated.
