These two words sound identical when spoken, but they are not spelling variants of each other. They are separate words — homophones — each with its own meaning and history. The confusion usually comes from not knowing that seel exists at all.
The Short Answer
Seal is the word you almost certainly want. It has several common meanings: to close something securely, a wax or adhesive closure, a stamp or emblem, or the marine mammal.
Seel is a specialized term from falconry. It means to sew shut the eyelids of a young hawk during its early training. Outside of falconry history, literature, or academic contexts, you will rarely encounter it.
What “Seal” Means
Seal covers a lot of ground as both a verb and a noun.
As a verb:
- To close or fasten something so it cannot be easily opened: She sealed the envelope before dropping it in the mailbox.
- To make something airtight or watertight: The plumber sealed the pipe joint.
- To confirm or settle something definitively: The handshake sealed the agreement.
As a noun:
- An emblem, stamp, or mark of authority: The document bore the official seal of the court.
- A wax or adhesive material used to close a letter or container: The wax seal on the bottle was still intact.
- The aquatic mammal: We watched a seal sunning itself on the rocks.
Seal is one of those words that has accumulated meanings over centuries, but the common thread is the idea of closing, confirming, or marking — plus the entirely separate animal meaning.
What “Seel” Means
Seel is a verb from the world of falconry. When a falconer seeled a hawk, they used thread or a thin cord to temporarily sew the bird’s eyelids shut. This was done during the early stages of training to keep the bird calm and reduce its fear responses while it adjusted to handling by humans. Once the hawk was sufficiently trained and settled, the stitches would be removed.
The practice dates back centuries and appears in historical falconry manuals as well as in English literature. Shakespeare used the word — in Macbeth, the phrase “Come, seeling night” refers to night blinding the eye of pity, drawing on the falconry sense of the word.
Outside of those specialized contexts — historical texts, discussions of falconry, or literary analysis — seel rarely appears in modern writing.
Why the Confusion Happens
The two words are pronounced exactly the same: both rhyme with feel, heel, and deal. If you hear someone say “seal” aloud, there is no way to know from sound alone whether they mean the closure, the animal, or the falconry term. Context almost always resolves it, because seel belongs to such a narrow domain that it virtually never appears in everyday conversation.
The confusion usually runs in one direction: a writer encounters seel in an older text or a Shakespeare play, does not recognize it, and wonders whether it is a misspelling of seal. It is not. They are genuinely different words.
Which Seal or Seel Should You Use?
In nearly every situation — writing a letter, describing the marine mammal, talking about a wax stamp, or using a verb meaning to close or confirm — the correct word is seal.
Use seel only when you are specifically writing about:
- the historical practice of falconry
- a literary text that uses the term
- the history or vocabulary of hawking
If you are editing someone else’s writing and see seel where seal seems expected, check the context before assuming it is a typo. In a historical or literary passage, it may be intentional and correct.
