Index vs glossy is a search that usually means index vs glossary, because glossy is a near neighbor of glossary. Index and glossary are both alphabetical lists found in books, which is why people mix them up. Glossy is a different word altogether, meaning shiny. Here is how all three work.

What does index mean?

An index is an alphabetical list of topics, names or terms, each followed by the page numbers where it is discussed. It usually sits at the very back of a nonfiction book and helps you find information without rereading chapters.

Index entries often include subentries and cross-references such as “see also.” Outside books, index has other meanings: a number that tracks change over time (a stock index or price index), a pointer used to speed up a database, and the index finger. For the plural, indexes is common for books, while indices is common in math and finance, and both are accepted.

What does glossary mean?

A glossary is an alphabetical list of specialized or unfamiliar terms, each with a short definition. It usually appears near the end of a book, report or manual, and it explains jargon so readers can follow along.

Textbooks, technical manuals and legal documents often include one. The word comes from the Latin glossarium, which goes back to the Greek glossa, meaning tongue or language. It shares its root with gloss in the sense of a short explanation of a hard word.

What does glossy mean?

Glossy is an adjective for something shiny, smooth and reflective, or something printed on shiny paper. Photo prints, magazine covers, paint and lip products can all be glossy.

It can also describe something that looks polished on the surface, as in a glossy presentation. As a noun, a glossy is a glossy magazine or photo print. It comes from gloss meaning shine, so it is a description of a finish and never a list in a book.

What is the difference between index vs glossy?

The difference between index vs glossy is that an index is a book section that points to pages, while glossy is an adjective that describes a shiny finish. The comparison most people actually want is index vs glossary.

• Index: answers “where?” with topics and page numbers.
• Glossary: answers “what does it mean?” with terms and definitions.
• Glossy: answers “how does it look?” with a word for shine.
• Word type: index and glossary are nouns, while glossy is mainly an adjective.

Is glossy a real word or a typo?

Glossy is a real word, but it is not a part of a book. If someone writes “the glossy at the back of the book,” they almost always mean glossary.

The two words differ only in their endings (-ary and -y), and a spellchecker will not flag glossy because it is a valid word. That is why the typo survives so often.

Does a book need both an index and a glossary?

Not always. A novel usually needs neither, while textbooks, manuals and reference books often include both. They do different jobs.

An index helps readers find information, and a glossary helps readers understand it. When both are present, the glossary conventionally comes before the index, and the index is usually the last item in the book.

How can you remember which one to use?

Ask which question you are answering. If it is “where can I find this?” use index. If it is “what does this word mean?” use glossary. If you are describing shine, use glossy.
