Editing Plautdietsch (section)

===Unique developments===
Not only has Plautdietsch undergone vowel shift, various dialects of Plautdietsch have also had their own shifts.<ref>Burns, Roslyn. 2015. The Plautdietsch Vowel Shift Across Space and Time. ''Journal of Linguistic Geography'' 3.2: pp 72- 94.</ref>

# This shift is still active, as some speakers {including a few from Hague} still retain the older pronunciation.{{Citation needed|reason=How do we know a sound change is still active and that this is not just a separate later innovation? Documents from Quiring 1928 show these changes, and to say that the change is still active means that this change has been active for 84 years.|date=August 2012}}

The deletion of r has been completed in most final positions, after front vowels and before alveolar consonants, but is still retained in the infinitive of verbs, after short vowels, and sometimes after back vowels as seen in the example Huarn, Hieena.

# {{IPA|/æ/}} shifted to {{IPA|/au/}} before voiced consonants.

====Palatalization====
All words with a {{IPA|/ɡ/}} or {{IPA|/k/}} preceding or following a front vowel ({{IPA|/e/}} or {{IPA|/i/}}, not counting [[schwa]]) have been shifted to {{IPA|/j/}} and {{IPA|/c/}} (the latter has been written as kj or tj), even if there is another consonant between the vowel and the consonant. An intervocalic {{IPA|/ɡ/}} is palatalized as the [[voiced palatal stop]] {{IPA|/ɟ/}}, written gj or dj. (A similar event occurred with English, but not as generalized). Where an {{IPA|/e/}} or {{IPA|/i/}} has been sunken to {{IPA|/a/}}, the palatalized sound is retained. Also where German has a palatalization (of the [[High German consonant shift|shifted]] {{IPA|/ç/}} consonant), Plautdietsch retains the palatalization (of {{IPA|/k/}}) even after lowering a front vowel.
