The future passive participle or the potential participle as it is sometimes called, is formed by adding -tabba / -anīya to the base of the verb; -tabba is mostly added with the connecting vowel -i-.

These participles are declined like a ending nouns in the masculine and neuter genders, and like ā ending nouns in the feminine. They express ideas such as ‘must,' ‘should be' and ‘fit to be.'
