University Park: Pennsylvania State University Press, 1974. — x, 358 p. — ISBN: 0271011718.This book represents a grammatical analysis of the only extensive connected texts in Old Prussian, namely, the three translations of Luther's Catechism, all dating from the middle of the 16th century and comprising about 66 pages of OP text. Schmalstieg first tackles the phonology, including the critical subheadings of orthography, vowels, stress, and consonants; it then proceeds to morphology, with more or less extensive subdivisions for nouns, adjectives, numerals, adverbs, pronouns, prefixes, prepositions, conjunctions, verbs, the non-finite forms of the verb, and the periphrastic tenses.
