seal

Flippered Arctic swimmer

Seal is two words.

First, a seal is something that secures or prevents escape, like the seal on a gasket.

Closely related to this meaning is something that confirms – in other words, makes it secure, like an official seal affixed to a document.

When you seal something tangible, you secure it with a seal.

When you seal a deal or agreement, you make it official.

The second meaning of seal is an aquatic mammal with sleek fur, or the fur harvested from one.
