Adjectives & Agreement

2-1-2 declension, the three positions (attributive, predicate, substantival), two-form adjectives, adverbs in -ως, comparatives, and superlatives.

Triple agreement

How Adjectives Agree

In English, "good" is identical for "the good man," "the good woman," "the good men," "the good women." In Greek, the adjective agrees with its noun in three categories at once:

So "good" has 24 possible forms (3 × 2 × 4).

The good news: most adjective endings are exactly the same as the noun endings you've already learned.

02 / 22
The standard pattern

The 2-1-2 Pattern — καλός, καλή, καλόν

Most adjectives use 2nd-decl endings for masculine and neuter, and 1st-decl endings for feminine. Hence "2-1-2."

Reading the lexicon

Adjective Lexicon Conventions

καλός, ή, όν — three endings
Standard 2-1-2 adjective. Three separate forms: masc, fem, neut. The second and third entries show only the endings — the stem stays the same.
αἰώνιος, ον — two endings
Two-form / 2-2-2 adjective. No separate feminine — masc and fem share the masculine forms; only the neuter differs. We'll meet this trap shortly.

Irregular #1

μέγας ("great") — Short-stem Surprise

663 NT occurrences. Four short-stem forms in masc/neut nom & acc singular. Everywhere else: extended stem μεγαλ- + standard endings.

Masc sgFem sgNeut sg
Nomμέγαςμεγάλημέγα
Genμεγάλουμεγάληςμεγάλου
Datμεγάλῳμεγάλῃμεγάλῳ
Accμέγανμεγάληνμέγα

💡 Memory hook: only 4 short forms — μέγας / μέγαν / μέγα / μέγα. English "megaphone" comes from this root.

05 / 22
Irregular #2

πολύς ("much, many") — Same Pattern

416 NT occurrences. Same scheme as μέγας: short stem in masc/neut nom & acc sg; doubled stem πολλ- everywhere else.

Masc sgFem sgNeut sg
Nomπολύςπολλήπολύ
Genπολλοῦπολλῆςπολλοῦ
Datπολλῷπολλῇπολλῷ
Accπολύνπολλήνπολύ

💡 Memory hook: only 4 short forms — πολύς / πολύν / πολύ / πολύ. Common phrase: πολλοὶ λέγουσιν ("many say").

⚠ Gotcha — πολύς (nom sg) vs πολλῶν (gen pl) look completely different. Memorize the short forms separately first.

The Three Positions

An adjective can stand in three positions relative to its noun. Each conveys a different meaning.

PositionPatternExampleMeaning
Attributive 1start + adj + nounὁ καλὸς λόγος"the good word"
Attributive 2ndart + noun + art + adjὁ λόγος ὁ καλός"the good word" (emphatic)
Predicateadj + art + noun (no second art)καλὸς ὁ λόγος"the word IS good"
07 / 22
⚠ The decisive rule

Inside the Article-Noun Group?

The adjective is attributive if it sits inside the article-noun group; predicate if it sits outside.

ὁ καλὸς λόγος
"the good word" — a noun phrase. Attributive (adj has an article in front of it).
ὁ λόγος καλός
"the word [is] good" — a complete sentence. Predicate (adj has no article in front of it). Greek doesn't need "is."

Article placement is what changes the meaning. If the adjective is preceded by an article, it's attributive. If it stands alone (no article in front, even though the noun has one), it's predicate.

08 / 22
Adjectives as nouns

Substantival Use

An adjective with an article but no noun functions as a noun in its own right. The gender tells you what kind of person or thing.

ὁ ἀγαθός
ho agathos
"the good [man]" — masc, so a person.
οἱ ἅγιοι
hoi hagioi
"the holy ones" = "the saints" — Paul's standard term for believers.
τὸ ἀγαθόν
to agathon
"the good [thing]" — neuter, abstract concept. Frequent in Romans 7.
οἱ νεκροί
hoi nekroi
"the dead" — masc plural.
09 / 22
⚠ The gender-mismatch trap

Two-Form Adjectives

Some adjectives have only two endings instead of three. Masculine and feminine share the same form; only neuter differs.

ἡ ἀδύνατος ὁδός
"The impossible road." = fem article. ὁδός = fem noun. ἀδύνατος looks masculine (-ος ending) — but it isn't. It's a two-form adjective; its feminine form is identical to its masculine.

Reading habit when you see a gender mismatch:

  1. Trust the article first. The article tells you the noun's actual gender.
  2. Check the lexicon. Two-form entries list only two endings: ἀδύνατος, ον (no separate fem).
  3. Translate normally. The adjective IS agreeing — Greek just uses one form for both genders here.
10 / 22
High-frequency two-forms

Common Two-Form Adjectives

Many — though not all — are formed with prefixes: ἀ- ("not"), εὐ- ("well"), δυσ- ("ill"). The compounding flattened the gender distinction.

ἀδύνατος, ον
"unable, impossible"
ἀ- "not" + δύνατος "able"
ἄπιστος, ον
"unbelieving"
ἀ- + πιστός "faithful"
αἰώνιος, ον
"eternal"
in ζωὴ αἰώνιος "eternal life"
ἄδικος, ον
"unrighteous"
ἀ- + δίκαιος
ἁμαρτωλός, όν
"sinful"
also functions as noun: "sinner"
ἔρημος, ον
"deserted, desolate"
ἀκάθαρτος, ον
"unclean"
ἀ- + καθαρός
11 / 22
From adjectives to adverbs

Spotting -ως Adverbs

Most words ending in -ως are adverbs of manner — "well," "truly," "righteously." Three diagnostic questions:

  1. Is it modifying a verb? If yes, almost certainly an adverb.
  2. Can you find the related adjective? Strip -ως, add -ος. καλῶςκαλός. ἀληθῶςἀληθής.
  3. Translate naturally. Often parallels English -ly: δικαίως = "righteously."
Formation rule (for reference)
καλός → gen pl καλῶν → adverb καλῶς ("well"). Take the genitive plural, change final ν to ς.
12 / 22
⚠ A trap

-ων Could Be Adverb OR Genitive Plural

Not every -ως / -ων word is an adverb. Genitive plural noun and adjective endings also end in -ων.

ἀνθρώπων
Ends in -ων, but it's a genitive plural noun, not an adverb. "Of humans." Modifies another noun.
καλῶς
Ends in -ως with a circumflex. Modifies a verb. Adverb of manner: "well."

The real giveaway: genitive plurals attach to nouns; adverbs attach to verbs. Look at what surrounds the word.

Adverbs That Don't End in -ως

τότε
"then, at that time"
ἤδη
"already, now"
πάλιν
"again"

Greek "greater / greatest"

Comparative & Superlative — 4 Endings

When you see one of these endings on an adjective stem, you've spotted a comparative or superlative form:

-τερος, -α, -ον
regular comparative
"more X" — ἰσχυρότερος "stronger"
-τατος, -η, -ον
regular superlative
"most X" — rare in NT
-ων, -ον (3rd-decl)
irregular comparative
μείζων "greater" (from μέγας)
-ιστος, -η, -ον
irregular superlative
μέγιστος "greatest"
16 / 22
⚠ Don't over-translate

Comparative Often Means Superlative

By NT times, the superlative form had become rare. Speakers used the comparative form for both "more X" and "most X" — context decides.

So μείζων ("greater") might mean:

True comparative
"greater than [X]" — usually with or a genitive nearby
Superlative force
"greatest" — when no comparison-target appears, the form is just emphatic
Elative force
"very great, exceedingly great" — neither comparative nor superlative; just intensified

A single Greek form can yield three different English translations depending on context.

18 / 22
Three ways to express comparison

How Comparison Is Expressed

Comparative + genitive of comparison
μείζων τῶν προφητῶν = "greater than the prophets." The thing compared to goes in the genitive.
Comparative + ἤ ("than") + same case
μείζων ἢ οἱ προφῆται = "greater than the prophets" (both items nominative).
μᾶλλον + adjective
No suffix at all. μᾶλλον δίκαιος = "more righteous." Works with any adjective.

Theologically loaded adjectives

Vocabulary — καλός vs. ἀγαθός

καλός — "good, beautiful, fine"
~100x. Beautiful, noble, fine in quality. The Greeks didn't separate aesthetics from ethics — the truly good thing was also the truly beautiful thing. The Good Shepherd is ὁ ποιμὴν ὁ καλός.
ἀγαθός — "good (morally), beneficial"
~102x. Morally good, beneficial. When the rich young ruler asks Jesus "Good teacher (διδάσκαλε ἀγαθέ)..." and Jesus replies "Why do you call me good (ἀγαθόν)?" — Jesus is making a moral-theological point: only God is good in the absolute sense.
ἅγιος — "holy, set apart"
~230x. Originally "marked off, separated" — set apart for the divine. Used of God ("the Holy Spirit") and of believers ("the saints" = οἱ ἅγιοι, Paul's term for ordinary Christians). English: hagiography.

Adjective position in action

John 10:11 — "I am the good shepherd"

Ἐγώ εἰμι ὁ ποιμὴν ὁ καλός· ὁ ποιμὴν ὁ καλὸς τὴν ψυχὴν αὐτοῦ τίθησιν ὑπὲρ τῶν προβάτων.

"I am the good shepherd; the good shepherd lays down his life for the sheep."

Adjectives Mastered

ὁ ποιμὴν ὁ καλός

2-1-2 declension, three positions (attributive / predicate / substantival), two-form adjectives, -ως adverbs, and comparatives. With these tools you can read most adjectival constructions in the NT.

The decisive rule: adjective inside the article-noun group = attributive. Outside = predicate.
