In retirement from the profession of librarianship, it was the authors' intention to do some writing in his mother tongue of Plautdietsch, a dialect of Nether Saxon Low German, or Niederdeutsch. In his childhood (in the 1930s and 40s) this dialect was still widely spoken in Central Kansas and in various areas of Canada. Today it is in dire danger of extinction. The discovery that a knowledge of verb forms was indispensable, lead to an attempt to conjugate a few verbs in all the tenses. That attempt has now grown to a large total of verbs, 501 of which are included in this collection. Publications of such collections of conjugations are common in all major languages. The conjugations consist of the 6 simple and 6 perfect tenses in the indicative mood, 1 simple and 1 perfect tense in the conditional mood, and 6 simple and 6 perfect tenses in the subjunctive mood. With each verb are included its English and German equivalent infinitives. These are listed in 2 indices which follow the conjugations: an English-Plautdietsch index and a German-Plautdietsch index, which enable a person to find instantly the Plautdietsch verb he wishes to use.
