* Vocabulary is influenced by many factors: Education, reading habits, profession, interests, and even personality can all shape the words someone uses.
* Age is a spectrum: People of different ages can have very similar vocabularies. Some young people have extensive vocabularies, while some older people might have smaller ones.
* Vocabulary isn't static: Our vocabulary changes throughout life. We learn new words, forget old ones, and our usage patterns shift.
Think of it this way: If you hear someone use the word "ubiquitous," you might assume they're well-read. But that doesn't mean they're old. They might be a young student of literature or a tech-savvy teenager.
In conclusion: While vocabulary can give hints about a person's background or interests, it's not a reliable indicator of age.
