Sign languages are full natural languages with their own grammar, unrelated to the spoken languages around them.
Wanib Sign Language is a reported sign language, possibly a village sign language, in a Heyo-speaking community of Papua New Guinea. It's spoken just to the west of Mehek Sign Language, but the two languages reflect the very different spoken languages of their communities: Wanib SL follows the SVO word order of Heyo, whereas Mehek SL follows the SOV word order of Mehek.
