One of the main differences is in the way that word-initial vowels are written. In Arabic, /in/ is (إن); in Jawi (Malay), it is (ان). In Tausug, it is (ئِن). The Tausug Arabic script utilises the letter yā' with a hamza (ئ) to represent a short vowel. If a kasra (ئِ) is added, it becomes an 'i' sound. If a fatha (ئَ) is added, it becomes an 'a' sound. If a damma (ئُ) is added, it becomes a 'u' sound. Tausug has three pronouns sets:  The case markers of Tausug are:  Non-subject undergoers take the oblique marker when definite or a proper noun, but indefinite common nouns take the genitive marker "sin". The positive existential ("there is") is "aun", the negative existential ("there is none") is "way". Verbs in Tausug are inflected for focus and aspect. Affixes expressing ability: Tausug numerals:  Many Tausug words derive from the Arabic language. Some examples of Arabic words in Tausug are Tausug words derived from Sanskrit
