The main difference between Dictionary and Glossary is that the Dictionary is a collection of words and their meanings and Glossary is a alphabetical list of terms relevant to a certain field of study or action.
Dictionary is a compilation of words and their meanings and usages. It is highly useful for the student and the writer alike. On the other hand, a glossary is nothing but a word list. It is a list of words that appear in a particular chapter or a lesson. This is the main difference between the two words, namely, dictionary and glossary.
