Tausug Dictionary is a dictionary of the Tausug language, a language spoken in the Sulu Islands in the Philippines. The dictionary is the first of its kind in the Philippines and is an important tool for learning the Tausug language. It is based on the work of the Summer Institute of Linguistics (SIL), an inter-governmental organization that is responsible for the teaching of the Tausug language in the Philippines.

The dictionary is a compilation of all the words that are considered important for the Tausug language. It is divided into two parts. Each part is divided into sections, and each section is divided into words. It is possible to mark a word as a verb, a noun, or a verb conjugated in the past or present tenses. It is also possible to add an example of how a word should be pronounced.

The dictionary contains a large number of words that are not found in other dictionaries. This is because the dictionary is based on the work of the Summer Institute of Linguistics.
