Dutch Sign Language

Dutch Sign Language (Dutch: Nederlandse Gebarentaal or NGT; Sign Language of the Netherlands or SLN) is the predominant sign language used by deaf people in the Netherlands.

Although the same spoken Dutch language is used in the Netherlands and Flanders, the Dutch Sign Language (NGT) is not the same as Flemish Sign Language (VGT). They do have the late 18th-century Old French Sign Language as their common ancestor, but have diverged during the subsequent 200 years, so that mutual intelligibility between modern users has been greatly reduced.
