Although deaf sign pagsasaos have emerged naturally in deaf communities alongside or among spoken pagsasao, they are unrelated to spoken pagsasao and have different grammatical structures at their core. A group of sign ""pagsasao"" known as manually coded pagsasaos are more properly understood as signed modes of spoken pagsasao, and therefore belong to the pagsasao family of the spoken pagsasao. One example of such a signed pagsasao is Warlpiri Sign Pagsasao, which belongs to the family of Ngarrkic pagsasao.
