Moths Ordbog (Late 17th - early 18th century). Matthias Moth's Dictionary is a historical dictionary of Danish c. 1700, involving both the spoken and the written language. Danish is the core of the dictionary but Danish words are accompanied by Latin equivalents. The dictionary contains 105,286 searchable headwords. It falls into two sections, a dictionary of ordinary words (entryid: 63...), and an encyclopedia (entryid: 64...) . A smaller portion of entries from letters O, P, and R (entryid: 644...) originate from earlier drafts, as the later versions were lost in a fire in connection with the Battle of Copenhagen in 1807. Moth's Dictionary consists of 62 handwritten volumes in folio which are stored in the Royal Library in Copenhagen.

The full entry structure consists of: Headword, (sometimes accompanied by variants and synonyms) Part of speech Possibly information on usage Inflection One or more Danish definitions Latin equivalent/translation (or parallel), with author One or more Danish multi-word expressions or usage examples Latin equivalent/translation (or parallel) of the MWEs/examples, with author Many entries hold only a small subset of this information.

In the encyclopedic entries, equivalents in other languages than Latin are sometimes provided, e.g. for place-names.
