Abecedarium is a term that is often used to refer to an alphabetical list, especially of words or names. However, if you're looking for alternative words to use, there are a few options to consider. For example, you might use the term glossary, which is a list of specific terms with their definitions. Alternatively, you can use lexicon, which refers to all the words in a language or specific field of study. Another option is the word vocabulary, which refers to the entire set of words used by a particular person or group. Whatever term you choose, the key is to select one that accurately describes the type of list you're creating.
