Unabridged dictionaries are large in size because they include all words in use at the time the dictionary is compiled. Abridged or desk and collegiate dictionaries are smaller and include only a selection of words. Foreign language dictionaries focus on a different language, perhaps French or German. Bilingual or multilingual dictionaries provide corresponding words in different languages. As with encyclopedias, dictionaries may also focus on a specific subject or discipline.
Glossaries are dictionaries or lists of specialized words.
