First Declension

Feminine nouns and the feminine article. The largest noun pattern in Greek — three subpatterns, all variations on one theme. Plus two new cases: the genitive and the dative.

Two new cases this lesson

Adding Genitive and Dative

Lesson 4 gave you nominative (subject) and accusative (direct object). This lesson adds the other two main cases:

CasePrimary functionEnglish equivalent
GenitivePossession; source; description"of X" / "X's"
DativeIndirect object; means; location; time"to X" / "for X" / "with X" / "in X"

ὁ λόγος τοῦ θεοῦ = "the word of God." λέγει τῷ ἀνθρώπῳ = "he speaks to the man."

⚠ Gotcha

Genitive Is More Than "of"

Translating every genitive as "of" works most of the time but will occasionally produce nonsense or obscure meaning.

The genitive expresses many relationships:

When the genitive is theologically important, don't settle for "of" — think about the actual relationship.

03 / 22
The most flexible case

The Dative — Broadest of All

Beyond indirect objects, the dative can express many things:

Indirect object
"to X / for X" — recipient of an action.
Means / instrument
"by X / with X" — what the action uses.
Location
"in X / at X" — where the action happens.
Time when
"on X / at X (time)" — when the action happens.

Don't try to master every nuance now. Learn it as the "to/for X" case at first.

A unified system

First Declension — Three Subpatterns

First declension is dominated by feminine nouns. Three variations, distinguished by what the stem ends in. Once you know the nominative form, the rest follows.

Stem ends in...SubpatternExample
ε, ι, or ρPure ακαρδία — "heart"
σ, ζ, ξ, λλα/η alternatingδόξα — "glory"
anything elsePure ηγραφή — "scripture"

You don't need to memorize the rule — once you see the nominative, the singular pattern is visible.

05 / 22
Subpattern 1

Pure α — καρδία ("heart")

SingularPlural
Nomκαρδίακαρδίαι
Genκαρδίαςκαρδιῶν
Datκαρδίκαρδίαις
Accκαρδίανκαρδίας

Used when the stem ends in ε, ι, or ρ. Examples: ἡμέρα (day), οἰκία (house), ἀλήθεια (truth).

Note the iota subscript in the dative singular (-ᾳ) — silent, but it tells you the case.

06 / 22
Subpattern 2

Alternating α/η — δόξα ("glory")

SingularPlural
Nomδόξαδόξαι
Genδόξηςδοξῶν
Datδόξδόξαις
Accδόξανδόξας

Singular alternates between α and η: nom/acc keep α, but gen/dat switch to η.

⚠ Common error: declining δόξα as δόξα, δόξας, δόξᾳ, δόξαν. Wrong — gen/dat are δόξης, δόξῃ.

07 / 22
Subpattern 3

Pure η — γραφή ("scripture")

SingularPlural
Nomγραφήγραφαί
Genγραφῆςγραφῶν
Datγραφγραφαῖς
Accγραφήνγραφάς

Used when the stem ends in any other consonant. Examples: ἀγάπη (love), εἰρήνη (peace), ζωή (life).

Memory hook

The Plurals Are Identical

The cheapest paradigm in Greek: all three 1st-declension subpatterns share the same plural endings.

PluralEnding
Nom pl-αι
Gen pl-ων
Dat pl-αις
Acc pl-ας

Learn it once, apply to every feminine noun. The differences between subpatterns only appear in the singular.

💡 The article is the anchor. If you know the article, you know the case even if the noun ending is ambiguous. Drill the feminine article as a separate paradigm until it's automatic.

⚠ Don't confuse

Article vs. Conjunction

 vs. 
= feminine nominative singular article ("the"). Has rough breathing.
= the conjunction "or, than." Has smooth breathing + an accent.
Look at the breathing mark.
οἱ  vs.  αἱ
οἱ = masc nom pl ("the men"). αἱ = fem nom pl ("the women"). Both have rough breathing, both end in iota — distinguished by the first letter only. Both pronounced "hoi" / "hai."

Lexical fact

Verbs That Take Genitive Objects

Direct objects normally take accusative. But: verbs of perception, ruling, accusation often govern the genitive.

ἀκούω
"I hear"
+ gen of person heard. ἀκούω τῆς φωνῆς = "I hear the voice." (NT freely takes acc too.)
κρατέω
"I take hold of"
+ gen
ἅπτομαι
"I touch"
+ gen
ἄρχω
"I rule"
+ gen ("rule over")
μνημονεύω
"I remember"
+ gen
ἐπιθυμέω
"I desire"
+ gen
12 / 22
Another lexical fact

Verbs That Take Dative Objects

Verbs of obeying, helping, trusting, serving, following often govern the dative.

πιστεύω
"I believe"
+ dat. πιστεύω τῷ θεῷ = "I trust God." With εἰς + acc → "believe into" (committal trust).
ὑπακούω
"I obey"
+ dat
δουλεύω
"I serve as a slave"
+ dat
διακονέω
"I serve, minister to"
+ dat
ἀκολουθέω
"I follow"
+ dat
προσκυνέω
"I worship"
+ dat (sometimes acc in NT)
ἀρέσκω
"I please"
+ dat

⚠ Reading habit

Don't Assume the Wrong Case

When you see a verb with what looks like a "wrong" case for an object, don't assume the verse is doing something exotic. Check whether the verb is one of these.

The case isn't a bug — it's part of how the verb works in Greek. In your lexicon, look for entries that say "+ gen" or "+ dat" after the verb's English gloss.

A practical reading habit
When you encounter ἀκούω, πιστεύω, ἀκολουθέω, προσκυνέω, your eye should scan for genitive (with ἀκούω) or dative (with the others) before assuming an accusative direct object will appear.

The most famous verse

John 3:16 — Every Case in Action

Οὕτως γὰρ ἠγάπησεν ὁ θεὸς τὸν κόσμον, ὥστε τὸν υἱὸν τὸν μονογενῆ ἔδωκεν, ἵνα πᾶς ὁ πιστεύων εἰς αὐτὸν μὴ ἀπόληται ἀλλ' ἔχῃ ζωὴν αἰώνιον.

ζωή is a 1st-decl pure-η feminine, just like γραφή; ζωήν is its accusative singular.

Vocabulary highlights

ἀγάπη, ζωή, δόξα

ἀγάπη — "love"
~116 NT occurrences. The "love" word the NT writers preferred for God's love and Christian love. Greek had ἔρως (romantic, never in NT), φιλία (friendship, 2x), στοργή (familial, never in NT). ἀγάπη was elevated to mean self-giving, willed love — love as a posture of action, not a feeling.
ζωή — "life"
~135x. Where Greek has two words for life, ζωή is metaphysical / vitality-of-being; βίος is day-to-day. Eternal life (ζωὴ αἰώνιος) uses ζωή — quality of life, not duration.
δόξα — "glory"
~165x. Originally meant "opinion" (Plato). LXX co-opted it to render Hebrew kavod (manifest weight/radiance of God's presence). Follows the alternating α/η pattern. English derivatives: doxology, paradox, orthodox.
16 / 22
More vocabulary highlights

γραφή, καρδία

γραφή — "writing, scripture"
~50x. Plural (αἱ γραφαί) almost always means "the Scriptures" (the OT for NT writers). Singular often points to a specific passage. Pure η subpattern. From γράφω ("I write") comes the perfect γέγραπται ("it stands written") — the standard formula introducing OT quotations.
καρδία — "heart"
~156x. Pure α subpattern. For Hebrews and Greeks alike, the heart was the seat of will, intellect, and emotion together — not narrowly emotion. "Love the Lord with all your heart" means whole-person commitment, not just feelings. English: cardiac, electrocardiogram.

Sentences in Three Genders

The article tells you the gender at a glance.

ἡ ἀγάπη τοῦ θεοῦ
hē agapē tou theou
"the love of God" — fem nom ἡ ἀγάπη + masc gen τοῦ θεοῦ.
ἡ βασιλεία τῶν οὐρανῶν
hē basileia tōn ouranōn
"the kingdom of heaven" (Matthew's signature) — fem nom + masc gen pl ("of the heavens").
δόξα τῷ θεῷ ἐν ὑψίστοις
doxa tō theō en hypsistois
"Glory to God in the highest" (Luke 2:14). δόξα nom (predicate). τῷ θεῷ dat (recipient). ἐν + dat pl.
18 / 22
⚠ Subjective vs. objective genitive

"The Love of God" — Which Direction?

The phrase ἡ ἀγάπη τοῦ θεοῦ is grammatically ambiguous:

Subjective genitive
"the love that God has" — God is the one doing the loving. (Romans 5:5.)
Objective genitive
"the love we have for God" — God is the one being loved. (Other passages.)

Both are grammatically possible. Context decides. This ambiguity is part of why genitive case is the most exegetically rich case in Greek. Whole branches of theology grow from differing answers (e.g., Luther's δικαιοσύνη θεοῦ).

19 / 22
Cultural note

Why Greek Has So Many Cases

English uses prepositions for almost everything: of/to/for/with/by/in the man. Greek does the same work with case endings alone. Why?

Greek is older and more conservative — it kept the case system that all Indo-European languages once had:

Each case can do many things. Reading Greek well requires not just identifying the case but interpreting which "function" of that case fits the context.

You Now Read Most NT Noun Phrases

ἡ ἀγάπη τοῦ θεοῦ

With Lesson 4 (2nd decl masculine/neuter) + Lesson 5 (1st decl feminine), you can decode the majority of noun phrases in the New Testament.

Drill the feminine article and the three subpatterns until they're automatic. Then we add 3rd-declension nouns (mixed gender, more variation) in Lesson 7.
