The resource that best helps a reader determine the meaning of technical words in a text is a dictionary.

The reference resource that best helps a reader determine the meaning of technical words in a text is a dictionary. A dictionary provides definitions, pronunciations, and often includes additional information such as word origins and usage examples. To use a dictionary, you can follow these steps:

1. Identify the technical word you want to understand in the text.
2. Look up the word in a reputable dictionary, either in print or online.
3. Pay attention to any additional information provided, such as part of speech, synonyms, or related terms.
4. Read the definition and any examples of usage to get a better understanding of the word and how it is used in context.

While a glossary is a useful resource that provides specific definitions for terms within a particular subject or field, it may not cover all technical words found in a text. An index helps find specific topics or terms within a book but does not provide definitions. A thesaurus, on the other hand, is helpful when you are looking for synonyms or different words with similar meanings but may not provide the specific definitions of technical words.
