Diego Collado's Grammar of the Japanese Language

A Latin-language grammatical treatise presents a systematic description of Japanese, beginning with a prologue and introductory discussion of phonology and morphology and then treating parts of speech in sequence: nouns, adjectives, pronouns, verbs with detailed conjugational paradigms, adverbs, particles, prepositions, and interjections. It proceeds to syntax, written-language issues, and numerical material, and reproduces the Latin original alongside an edited translation. An extended introduction and notes compare this account with a contemporary Arte, assessing descriptive choices and limitations, and the volume supplies editorial conventions, bibliography, textual corrections, and guidance for readers of the Latin text.
