Word for a page with definitions

I need a title for one of the pages in my application. It only contains words with their definitions. So this word is not going to be a part of a sentence but used as a title of the page and button name. Something like:

(title that I'm looking for)

car - a road vehicle with an engine plane - vehicle designed for air travel

I was thinking of word Reference or Definitions but maybe there is something more accurate.

Solution 1:

The title you are looking for, I think, is "glossary"

Traditionally, a glossary appears at the end of a book and includes terms within that book that are either newly introduced, uncommon, or specialized.

Solution 2:

How about Clavis?

Merriam Webster defines it as:

a key or glossary serving as an aid to interpretation

According to Wikipedia

Clavis or Glossary, an alphabetical list of terms in a particular domain of knowledge with the definitions for those terms
