Nehrungisch (Standard High German: Nehrungisch, Mundart der Danziger Nehrung or Mundart der Frischen Nehrung) is a subdialect of Low Prussian, belonging to the Low German language variety. It was spoken in East Prussia and West Prussia, in the region around the Vistula Spit (Frische Nehrung) near Danzig. The easternmost locality where this variety was spoken was Narmeln, and it was spoken from Narmeln to Krakau (Krakowiec). Its Eastern border was to Mundart der Elbinger Höhe,a Low Prussian variety. The dialect survives in Chortitza- Plautdietsch, a dialect of Plautdietsch brought to Ukraine by migrants from the Vistula region.^{[citation needed]} The distinguishing Chortitza features were present in the Northeast of the Vistula delta.

Nehrungisch shares features with Eastern Low Prussian.

Those of the Mennonites from the Vistula lowlands, that originated from the lower part of the Rhine belonged together with those from Gdańsk (Danzig), Elbląg (Elbing), and the Żuławy Gdańskie [pl] (Danziger Werder [de]) and entered the larger area in the second half of the 1540s. The majority of the Chortitza colonists were from the northernmost part of the Marienburger Werder, the Gdańsk Spit and the Gdańsk urban area. The Chortitza Colony Plautdietsch language had no major linguistic difference from the original Nehrungisch, which had changed by 1880. By then, the most conspicuous features (such as /eiw/ for /au/) were limited to the Vistula Spit. The border between Nehrungisch and Samlandic was between Narmeln and Neutief. Flemish Mennonites formed the majority in Chortitza Colony, the Frisian Mennonites settling separately in the same colony in Kronsweide, Schönwiese, Kronsgarten and Einlage. Einlage, Chortitza, had the largest Mennonite Brethren congregation of the country. Andreasfeld Mennonite Brethren Church was a daughter congregation, also in Chortitza. Sommerfelder, Reinländer Mennoniten Gemeinde, Evangelical Mennonite Mission Conference and the Gospel Mennonite Church are of Chortitza origin. Many south Mexican members of the Kleine Gemeinde are defectors from the Old Colony Mennonites. A number of words known on the Vistula Spit only in the 20th century were used in Danzig and the Weichselwerder at the beginning of the 19th century. Most residents of Chortitza Colony were from Żuławy Malborskie. The Pokraken congregation in East Prussia, members of Frisian congregations, migrated from West Prussia in 1713. It settled in Pokraken (present-day Leninskoye), Plauschwaren, Grigolienen, Bogdahnen, Neusorge, Sköpen (present-day Mostovoe), Elbings Kolonie (present-day Bolshaya Nemoninka), Grüneberg, Klubien and Allekneiten. Daughter colonies in northeastern Russia included Arkadak (with the villages of Wladmirowka, Borisopol, Dmitrowka, Marianowka, Wjasemskoje, Leonidowka and Lidjewka). Daughter colonies in Ukraine included Judenplan, Großfürstenland (with the villages of Georgstal, Sergejewka, Alexandertal, Michaelsburg, Olgafeld and Rosenbach), Bergtal (with the villages of Bergtal-Bodnja, Schönfeld, Schöntal, Heubuden and Friedrichstal), Tschornoglas (with the village of Gerhardstal), Borsenko (with the villages of Nowo-Sofiewka, Mariapol, Blumenfeld, Steinau, Hamburg, Neubergtal, Hoffnungsort), Nikolaipol (with the villages of Nikolaipol, Eichenfeld-Dubowka, Morosowo, Adelsheim-Dolinowka, Warwarowka, Tschistopol, Paulsheim-Pawlowka, Nadeshdowka [Iwangorod] and Jenelowka), Neplujewka (Starosawodskoje and Kislitschwewataja), Kusmitzky (with the village of Alexandrowka), Andreasfeld (with the village of Andreasfeld), Neu-Schönsee (with the village of Neu-Schönwise), Eugenfeld (with the village of Eugenfeld), Baratow (with the villages of Nowaja-Chortitza and Wodjanaja), Schlachtin (with the villages of Selenopol and Kamenopol), Neurosengart (with the villages of Neurosengart and Kronsfeld), Wiesenfeld (with the village of Wiesenfeld), Miloradowka (with the villages of Miloradowka and Jekaterinowka), Ignatjewo (with the villages of New Jork, Nikolajewka, Ignatjewo, Leonidowka, Romanowka, Jekaterinwoka and Alexejewka), Borissowo (with the villages of Ljubomirowka, Kondratjewka and Nioklaipol), Naumenko (with Grigorjewka, Petrowka, Wassiljewka and Jelenowka, mixed Chortzitza and Molotschna background), Zentral (with the village of Zentral) and Sadowaja (with the village of Anna). Yazykovo Mennonite Settlement was a daughter settlement of Chortitza and comprised several villages. Fürstenland Colony was founded by settlers from Chortitza. In the entire Soviet union, Chortitza Plautdietsch nouns in the masculine and neuter would only have the nominative case and an object case (in the dative form), in the feminine only one case (in nominative form), plural nouns would only have the object case anymore.

Furstenthal and Bergthal villages in West Reserve included the following:

Chortitza-Plautdietsch is spoken in Mexico, in Altkolonie and Blumenau. Chihuahua, Texas and Bolivia's Santa Cruz Department have Nehrungisch-speaking residents. Plautdietsch speakers in Belize speak Chortitza-Plautdietsch. Mennonites arriving in the country since 1958 were Mexican Old Colony Sommerfelder and Kleine Gemeinde. Some migrated to Canada or northern Mexico. Mennonites of Mexico, Texas, Canada, Belize, western Kansas, and Bolivia are connected.

Descendants of those who left Chortitza for Canada in the 1870s (who live in many Latin American countries) have weak palatalization. In 1891, Manitoba Bergthal families arrived in Saskatchewan. During the 1940s, Manitoba and Saskatchewan Altkolonie Mennonites began to emigrate to northern Mexico. Spoken Plautdietsch in Mexico, Bolivia and Texas differs from that in Canada. Chortitza-Plautdietsch is spoken in Paraguay's Menno Colony. Reinfeld Colony in the country's Misiones Department was founded by people from Paraguay's Sommerfeld and Bergthal settlements. In Mexico, the use of Chortitza-Plautdietsch depends on whether a speaker is one of the Old Colony Mennonites. Nineteenth-century Mennonite migrants to Canada primarily came from the Chortitza Colony. There is no strict difference of Chortitza and Molotschna Plautdietsch in British Columbia. Among Old Colony Mennonites, it is relatively frequent to use words from Russian or Polish, in contrast to using recent loanwords. Many speakers of Plautdietsch exhibit features of both Chortitza- and Molotschna-Plautdietsch. The central cluster around the South Saskatchewan River is largely in the core Old Colony and Bergthaler settlement region, demarcated by the boundaries of the Hague-Osler Mennonite Reserve. The peripheral cluster in the northern and western valley encompasses areas primarily settled by Russländer immigrants after the mass emigration of Old Colony and Bergthaler Mennonites to Latin America in the 1920s. Canadian Chortitza descendants formed the first Latin American settlements of Mennonites of Dutch origin in 1922 in Chihuahua, Mexico.

In 1983, conservative Mennonites in northern Mexico began moving to the south of the country. Some Belizean Mennonites formed communities such as those in Quintana Roo; others joined preexisting Mexican congregations, such as those in Campeche. In 2006, there were approximately 6,900 Plautdietsch speakers in Belize.

Mexican Mennonites settled in Seminole, Texas (moving north from the original 1870s settlement), Oklahoma and Kansas. Mennonites first arrived in Seminole in 1977 from Cuactémoc, Chihuahua. In 2005, it was estimated that there was an estimated 5,000 Mennonites of Latin American origin (Keel 2006) living in southwestern Kansas in 2005, centered around Meade.
