- A protective gasket or barrier that prevents air, water, or liquids from escaping.
For example:

Common Uses of Seal

- Business contracts
- Shipping and packaging
- Construction
- Engineering
- Government documents
- Medical packaging
- Food preservation
Because it has so many meanings, context tells readers which definition applies.
What Does “Seel” Mean?
Unlike seal, the word seel is almost never used in modern conversation.
Historically, seel meant:
To close or stitch together the eyelids of a hunting bird, usually a falk, to calm or train it.
This practice belonged to traditional falconry and is now considered outdated and inhumane.
Historical Meaning
Centuries ago, falconers sometimes temporarily closed a bird’s eyelids to make it easier to tame.
This process was called seeling.
Although historians still discuss the practice, it has disappeared from modern falconry.
Modern Usage
Today, you’ll usually encounter seel only in:
- Historical books
- Medieval texts
- Shakespearean literature
- Academic discussions about falconry
- Old dictionaries
Outside those settings, most English speakers never use the word.
Examples
- The falconer chose to seel the hawk before training.
- Medieval manuals described how birds were seeled during handling.
These examples sound unusual because the word itself has become obsolete.

This comparison highlights why seal appears thousands of times more often than seel.
Do Seal and Seel Sound the Same?
Yes.

Both words are spelled correctly, yet only one fits the sentence.
