However, it's important to note that "dearest" is most commonly used as a superlative adjective, meaning "most beloved." It's less common to use it as a noun, but it can be used to refer to a loved one or someone you hold dear.
For example:
* "My dearest, I miss you so much." (adjective)
* "She wrote a letter to her dearest." (noun)
Another way to use "dear" as a noun is in the phrase "a dear," which refers to a loved one or a friend.
* "I met a dear friend at the park."
