This is incorrect. It is not "the" language of Surinam. Only 120.000
are native speakers of this language. There are actually
MORE native speakers of Dutch (200.000)
Having lived in Surinam for quite some time and having gone to school there. Both Dutch and Sranan are used at school. And both are the official language. Sarnami Hindoestani which you call: Carribean Hindustani (150.000) is NOT an official language.
