Greek groups its nouns under three declensions. The declension of a noun tells us nothing about the meaning. Declension is merely a convenient way of grouping words by a common element, similar to arranging all words that start with "B" under the "B" section of a dictionary. As such, declension is entirely irrelevant to determining the meaning of a word or the role a word plays in a sentence.

DECLENSION GROUPINGS:

• 1st declension generally has an "A" sound in the ending.
• 2nd declension generally has an "O" sound in the ending.
• 3rd declension is for everything else—a somewhat mixed bag.

The declension of a noun has no significance to the meaning of the noun, and thus no relevance in translating.
