Isirawa is a Papuan language spoken by about two thousand people on the north coast of Papua province, Indonesia. It's a local trade language, and use is vigorous. Stephen Wurm (1975) linked it to the Kwerba languages within the Trans–New Guinea family, and it does share about 20% of its vocabulary with neighboring Kwerba languages. However, based on its pronouns, Malcolm Ross (2005) felt he could not substantiate such a link, and left it as a language isolate. The pronouns are not, however, dissimilar from those of Orya–Tor, which Ross links to Kwerba, and Donahue (2002) accept it as a Greater Kwerba language.

In Sarmi Regency, Isirawa is spoken in Amsira, Arabais, Arsania, Kamenawari, Mararena, Martewar, Nisero, Nuerawar, Perkami, Siaratesa, Waim, Wari, and Webro villages.^[2]

In Isirawa, the feminine gender is associated with big objects, and masculine with small objects; the opposite association is found in Tayap and the Sepik languages, which classify large objects as masculine rather than feminine.^[3]

The Isirawa pronouns are,

I	a-, e
we	nen-, ne
you	o-, mə
all third person	e-, maə, ce, pe

Ross's reconstructed Orya–Tor pronouns are *ai 'I', *ne 'we' (inclusive), *emei 'thou', *em 'you'.
