/*
Omitting names and compound forms, there are 595 second declension nouns in the New
Testament, 347 of which are masculine and follow the declension ἄνθρωπος, and 196 of which
are neuter and follow the declension of δῶρον. There are also several feminine nouns of the
second declension. These nouns follow the declension of ἄνθρωπος but use the feminine
definite article (e.g., ἡ ὁδός, “the way”; see John 14:6). Some second declension nouns are
irregular in their formation.

/*
If the stem of a word ends in the phonemes ε, ι, or ρ, then the α of the nominative singular
is retained throughout the declension (as in ἡμέρα). If the stem of a word ends in a sibilant
phoneme (ζ, σ, or a double letter containing σ, i.e., ξ, or ψ), then the α of the nominative
singular lengthens to -ης and -ῃ in the genitive and dative singular (as in δόξα). If the
stem of a word ends in a phoneme other than ε, ι, ρ, or a sibilant, then the η in the
nominative singular is retained throughout the singular (as in φωνή).
