The Physical Seal

In a physical context, \"seal\" usually refers to a device used to make an impression or mark, either for authentication or identification. For example, when on official documents or even on packaging for products, there might be a seal impressed with a stamp containing the maker's emblem or a government agency's emblem. In addition, when people engage in deep sea diving, they need to wear a special suit that has a rubber seal around the neck, legs, and arms so that water can't get inside.

The Animal Seal

On the other hand, \"seal\" can also refer to a type of marine mammal. Seals are well-known for their thick fur coats that they use to keep warm in the cold waters of the ocean. These mammals can be found in almost all of the world's oceans and can vary in size from only a few feet long to more than twenty feet long. Besides, as the food chain operates, different species of seals provide food for polar bears, killer whales, and sharks.

The Verbal Seal

Lastly, \"seal\" can also refer to a verbal act, representing closing, completing, or deciding something. For example, if you are selling a house or a car, you will usually need to sign a contract and then seal the deal by exchanging money or titles. In addition, the phrase \"sealed lips\" usually refers to keeping a secret or not telling anything confidential to others. When the use of \"seal\" is focused on the closure of a verbal act, it nearly always implies the conclusion of an event, with little or no possibility of further revision or alteration.

As we have learned from the above discussion, the meaning of \"seal\" can vary greatly, depending on the context in which it is used. It can be a physical device, an aquatic animal or related to a verbal act. All in all, \"seal\" represents a wide range of words and concepts and is often used to evoke a sense of authenticity, completion, or finality.
