Quick Answer
Seal is the correct word in almost all modern English writing. It refers to closing something securely, an official stamp, or a marine mammal.
Seel is a rare, old-fashioned English word that means to close or sew shut the eyes of a bird, especially in falconry. It is considered archaic and is almost never used in everyday English.
In modern writing, you should almost always use “seal.”
What Does “Seal” Mean?
The word seal has several common meanings depending on the context. It is one of the most frequently used words in English and appears in everyday conversations, business writing, legal documents, and technical communication.
Common meanings of seal include:
- To close something tightly
- To make something airtight or waterproof
- To officially approve a document with a stamp
- A marine mammal that lives in oceans
- A symbol of authority or authenticity

In nearly every modern situation, seal is the correct spelling.
What Does “Seel” Mean?
Seel is an old English verb that has survived mainly in historical literature and discussions about falconry. Traditionally, it meant to sew or close the eyelids of a hawk or falcon to calm or train the bird.
Because the practice is historical, the word itself has become extremely rare. Most English dictionaries label it as archaic or obsolete.
Examples of “Seel”
- The falconer decided to seel the bird before training.
- Ancient texts sometimes mention the practice of seeling hawks.
Outside historical discussions or literary works, you are very unlikely to encounter this word.

| Feature | Seel | Seal |

| Part of speech | Verb | Verb and noun |
| Meaning | To close a bird’s eyelids (archaic) | To close securely, approve officially, or marine animal |
| Everyday English | No | Yes |

Similar Pronunciation
Both words are pronounced almost exactly the same in standard English, making them homophones.
Nearly Identical Spelling

Spell Checker Limitations
Since seel is an actual English word, spell checkers may not always flag it as an error, even when you intended to write seal.
Lack of Familiarity
Most people have never encountered the word seel, so they may assume it is simply another spelling of seal.
