The plural is "-en" rather than "-(e)t", as is found in West-Veluws and Urkers and clearly from Dutch influence since a unified plural in "-(e)t" for verbs is common in Low Saxon. The dialects have "wiej warken" instead of "wiej warkt" for "we work". The feature is, surprisingly, also found in Stellingwarfs and Grunnegs. The trait is believed to have Frisian rather than Hollandic origins, however. The Stellingwerven have been West Frisian for centuries, and Groningen spoke East Frisian in the Middle Ages. Modern Frisian has "-e" there. "-en" might be a kind of intermediate form between "-t" and "-e". The unified plural takes the form "-et" rather than "-t" in the Achterhooks dialect of Winterswijk and in the more conservative southern Tweants varieties, which border the Achterhook.
