A suffix denoting a pair of an object that is the subject of a sentence, no matter what words are used to describe it.
All Nouns: add -ât to the end of the noun (remember vowel-combinations with Strong-II and Weak-II nouns!).
If it is a Strong-I noun with identical base and variable vowels, the noun will undergo A-syncope when the dual suffix is added.
Examples:
Kaliyât nakkham anâiyada urudnud.
“The two women came against the people on the mountain.”
Mî Miyât pûhim.
“The twins were crying.”
