The following Greek Nouns Declensions chart, available here as a downloadable PowerPoint presentation and here as a downloadable PDF, details all of the types and genders of nouns that the New Testament Greek student will encounter. I know of no other paradigm in existence that condenses all of these case endings—based on the “8-case” paradigm—into a single, concise chart of all Greek noun declensions. I call it the “satellite view” of all Greek noun endings. Of significant value are the horizontal relationships existing between each type of noun presented in a vertical layout that can be clearly observed in this comprehensive, single-page layout. Assisting in your memorization of these endings are the use of arrows showing either identical or similar continuity, and yellow highlights denoting pattern shifts.
* NΟΤΕ: The PowerPoint presentation also includes an overview of the “8-case” system, as well as a static view of the declension and translation of the 2nd declension masculine noun λόγος.
Of particular significance within the eight-case system for inflected noun endings are two additional cases not readily found in the more widely used five-case system. Sharing the same endings, singular and plural, as the Dative case are the Locative and Instrumental cases. As a memory aid, a helpful acronym for these three cases is to refer to them as the “L.I.D.” cases, particularly since their singular and plural forms always reveal, either an “iota subscript” or an iota “sandwiched” in between two other letters (e.g., –οις, –αις). So, the “L.I.D.” acronym has an “I” in it, and the endings also all have an “I” in them in the form of an iota. (Note: 3rd Declension L.I.D. plurals have –σι as their shared cases’ ending.)
It’s also noteworthy that Neuter nouns (pronouns, adjectives) always repeat their nominative endings in the accusative case (singular and plural, respectively).
There are various types of Greek nouns declined in the 3rd Declension, also called the “Consonant Declension.” These types derive their names based on the final letter(s) of their respective stems. Stems in this declension are not readily identifiable by referring to their Nominative singular (lexical) forms, but rather (usually) from their Genitive singular forms. It is helpful, therefore, for the student to memorize the Genitive singular stems of these types of “irregular” Greek nouns. For more on this click here.
