Contract verbs are one of the most important verb groups in New Testament Greek. They are called “contract verbs” because their stems end in a vowel that contracts with the vowel of the ending. This contraction changes the visible form of the verb. As a result, students may fail to recognize a familiar lexical form when it appears in an inflected form.
For example, the lexical form ἀγαπάω may appear as ἀγαπῶ. The lexical form ποιέω may appear as ποιῶ. The lexical form πληρόω may appear as πληρῶ. These forms are not irregular in the ordinary sense. They are contracted forms produced by predictable vowel combinations.
This lesson teaches students how to identify Greek contract verbs, especially verbs ending in -άω, -έω, and -όω. It explains the main contraction patterns, common forms, parsing shortcuts, and frequent mistakes. The goal is to help students recognize contract verbs quickly while reading the Greek New Testament.
What Is a Contract Verb?
A contract verb is a verb whose stem ends in a short vowel, usually α, ε, or ο. When the stem vowel meets the vowel of the ending, the two vowels contract into a single long vowel or diphthong.
| Contract Type | Lexical Ending | Example | Meaning |
|---|---|---|---|
| Alpha contract | -άω | ἀγαπάω | I love |
| Epsilon contract | -έω | ποιέω | I do, make |
| Omicron contract | -όω | πληρόω | I fill, fulfill |
The lexical form shows the uncontracted shape, but the forms in actual reading are usually contracted.
Why Contract Verbs Matter
Many high-frequency New Testament Greek verbs are contract verbs. Students who do not recognize contract patterns will misparse common forms.
Common contract verbs include:
- ἀγαπάω — I love
- γεννάω — I beget, give birth to
- ἐρωτάω — I ask
- ζάω — I live
- ποιέω — I do, make
- ζητέω — I seek
- καλέω — I call
- λαλέω — I speak
- τηρέω — I keep
- πληρόω — I fill, fulfill
- φανερόω — I reveal, make manifest
- δικαιόω — I justify
The Three Main Contract Verb Types
| Type | Stem Vowel | Lexical Form | Contracted First Singular |
|---|---|---|---|
| -άω | α | ἀγαπάω | ἀγαπῶ |
| -έω | ε | ποιέω | ποιῶ |
| -όω | ο | πληρόω | πληρῶ |
The contracted first singular forms may look identical in English transliteration, but the Greek spelling and broader paradigm reveal the contract type.
The Most Important Recognition Clue: Circumflex Accent
Many contracted forms show a circumflex accent. The circumflex often signals that contraction has occurred.
| Lexical Form | Contracted Form | Observation |
|---|---|---|
| ἀγαπάω | ἀγαπῶ | Alpha stem contracted with ending |
| ποιέω | ποιῶ | Epsilon stem contracted with ending |
| πληρόω | πληρῶ | Omicron stem contracted with ending |
The circumflex does not by itself prove every detail of the parsing, but it is a major visual clue.
Basic Contraction Principles
Contract verbs follow recurring vowel patterns. Students do not need to become historical linguists to parse them, but they should memorize the most common results.
| Stem Vowel | Common Result | Example |
|---|---|---|
| α + ο/ω | ω | ἀγαπάω → ἀγαπῶ |
| α + ε/η | α or ᾳ depending on form | ἀγαπάετε → ἀγαπᾶτε |
| ε + ο/ω | ου or ω | ποιέομεν → ποιοῦμεν |
| ε + ε | ει | ποιέετε → ποιεῖτε |
| ο + ο/ω | ου or ω | πληρόομεν → πληροῦμεν |
| ο + ε/η | ου or οι | πληρόετε → πληροῦτε |
For reading purposes, the most important point is that the visible ending may be contracted and therefore may not look like the ordinary λύω paradigm.
Alpha Contract Verbs: -άω
Alpha contract verbs have stems ending in α. The lexical form ends in -άω.
Common examples:
- ἀγαπάω — I love
- γεννάω — I beget, give birth to

- πεινάω — I hunger
- διψάω — I thirst
- ζάω — I live

Why Some Contract Forms Look Alike
Several contract verbs produce similar-looking forms. For example, ἀγαπῶ, ποιῶ, and πληρῶ all end in -ῶ. The ending alone does not reveal which lexical verb is involved. The stem must be identified.
| Contracted Form | Lexical Form | Contract Type |
|---|---|---|
| ἀγαπῶ | ἀγαπάω | -άω |
| ποιῶ | ποιέω | -έω |
| πληρῶ | πληρόω | -όω |
Therefore, students must identify both the ending and the stem.
Contract Verbs in the Imperfect
In the imperfect tense, contract verbs use augment, the present stem, and secondary endings. The same contractions still occur.
| Lexical Form | Imperfect Form | Parsing |
|---|---|---|
| ἀγαπάω | ἠγάπων | Imperfect active indicative, 1st singular or 3rd plural |
| ποιέω | ἐποίουν | Imperfect active indicative, 1st singular or 3rd plural |
| πληρόω | ἐπλήρουν | Imperfect active indicative, 1st singular or 3rd plural |
Notice that the imperfect forms may end in -ουν or -ων, depending on the contract type and form. Context identifies whether the form is first singular or third plural when the ending is ambiguous.
Contract Verbs in the Future
In the future tense, the contract vowel is usually lengthened before the future marker -σ-.
| Lexical Form | Future Form | Recognition |
|---|---|---|
| ἀγαπάω | ἀγαπήσω | α lengthens to η |
| ποιέω | ποιήσω | ε lengthens to η |
| πληρόω | πληρώσω | ο lengthens to ω |
| φανερόω | φανερώσω | ο lengthens to ω |
| τηρέω | τηρήσω | ε lengthens to η |
When students see forms such as ποιήσει, ἀγαπήσει, or πληρώσει, they should recognize the future marker and remember the contract stem behind the form.
Contract Verbs in the First Aorist
In the first aorist, contract verbs often show the same lengthened vowel before the aorist marker.
| Lexical Form | Aorist Form | Recognition |
|---|---|---|
| ἀγαπάω | ἠγάπησα | Augment + lengthened stem + -σα |
| ποιέω | ἐποίησα | Augment + lengthened stem + -σα |
| πληρόω | ἐπλήρωσα | Augment + lengthened stem + -σα |
| φανερόω | ἐφανέρωσα | Augment + lengthened stem + -σα |
| τηρέω | ἐτήρησα | Augment + lengthened stem + -σα |
A contract verb may look more recognizable in future and aorist forms because the stem vowel is lengthened rather than contracted with a present ending.
Contract Verbs in the Perfect
Perfect forms of contract verbs often show reduplication and a lengthened stem vowel.
| Lexical Form | Perfect Form | Recognition |
|---|---|---|
| ἀγαπάω | ἠγάπηκα | Perfect active form with lengthened stem vowel |
| ποιέω | πεποίηκα | Reduplication + lengthened stem + -κα |
| πληρόω | πεπλήρωκα | Reduplication + lengthened stem + -κα |
| φανερόω | πεφανέρωκα | Reduplication + lengthened stem + -κα |
| τηρέω | τετήρηκα | Reduplication + lengthened stem + -κα |
Students should always compare perfect forms with principal parts because not every verb behaves with perfect regularity.
Contract Infinitives
Contract verbs have distinctive infinitive forms. These are especially important because infinitives occur frequently.
| Contract Type | Lexical Form | Present Active Infinitive |
|---|---|---|
| -άω | ἀγαπάω | ἀγαπᾶν |
| -έω | ποιέω | ποιεῖν |
| -όω | πληρόω | πληροῦν |
More Contract Infinitive Examples
| Lexical Form | Present Active Infinitive | Aorist Active Infinitive |
|---|---|---|
| ἀγαπάω | ἀγαπᾶν | ἀγαπῆσαι |
| ἐρωτάω | ἐρωτᾶν | ἐρωτῆσαι |
| ποιέω | ποιεῖν | ποιῆσαι |
| ζητέω | ζητεῖν | ζητῆσαι |
| λαλέω | λαλεῖν | λαλῆσαι |
| τηρέω | τηρεῖν | τηρῆσαι |
| πληρόω | πληροῦν | πληρῶσαι |
| φανερόω | φανεροῦν | φανερῶσαι |
Contract Participles
Contract participles often show contracted vowels and circumflex accents.
| Lexical Form | Present Active Participle | Aorist Active Participle |
|---|---|---|
| ἀγαπάω | ἀγαπῶν | ἀγαπήσας |
| ἐρωτάω | ἐρωτῶν | ἐρωτήσας |
| ποιέω | ποιῶν | ποιήσας |
| ζητέω | ζητῶν | ζητήσας |
| λαλέω | λαλῶν | λαλήσας |
| πληρόω | πληρῶν | πληρώσας |
New Testament Examples of Contract Verb Recognition
John 14:15
Ἐὰν ἀγαπᾶτέ με, τὰς ἐντολὰς τὰς ἐμὰς τηρήσατε.
“If you love Me, keep My commandments.”
The form ἀγαπᾶτέ comes from ἀγαπάω. It is a contracted alpha-contract form. The form τηρήσατε comes from τηρέω and shows the aorist active imperative pattern with a lengthened stem vowel.
John 21:17
Κύριε, σὺ πάντα οἶδας, σὺ γινώσκεις ὅτι φιλῶ σε.
“Lord, You know all things; You know that I love You.”
The form φιλῶ comes from φιλέω. It is a contracted epsilon-contract form, present active indicative, first person singular.
Matthew 5:17
Μὴ νομίσητε ὅτι ἦλθον καταλῦσαι τὸν νόμον ἢ τοὺς προφήτας· οὐκ ἦλθον καταλῦσαι, ἀλλὰ πληρῶσαι.
“Do not think that I came to destroy the law or the prophets; I did not come to destroy, but to fulfill.”
The infinitive πληρῶσαι comes from πληρόω. It is an aorist active infinitive. The lengthened ω reflects the omicron contract stem before the aorist infinitive ending.
Parsing Shortcut 1: Look for the Lexical Ending
When learning vocabulary, notice whether the lexical form ends in -άω, -έω, or -όω. This tells you to expect contraction in the present system.
| Lexical Ending | Expect |
|---|---|
| -άω | Alpha contract forms such as -ῶ, -ᾷς, -ᾷ, -ᾶτε |
| -έω | Epsilon contract forms such as -ῶ, -εῖς, -εῖ, -οῦμεν, -εῖτε |
| -όω | Omicron contract forms such as -ῶ, -οῖς, -οῖ, -οῦμεν, -οῦτε |
Parsing Shortcut 2: A Circumflex Often Signals Contraction
Forms such as ποιῶ, ἀγαπῶ, πληρῶ, ζητεῖτε, ποιοῦμεν, and πληροῦται often reveal contraction through the circumflex accent.
When you see a circumflex in a verb ending, ask whether the form may come from a contract verb.
Parsing Shortcut 3: Identify the Stem Before the Ending
The ending -ῶ occurs in many contract verbs. Therefore, do not parse only from -ῶ. Identify the stem first.
| Form | Stem | Lexical Form |
|---|---|---|
| ἀγαπῶ | ἀγαπ- | ἀγαπάω |
| ποιῶ | ποι- | ποιέω |
| πληρῶ | πληρ- | πληρόω |
| ζητῶ | ζητ- | ζητέω |
Parsing Shortcut 4: Future and Aorist Often Show Lengthened Vowels
Contract verbs often show lengthened vowels in future and aorist forms.
| Contract Type | Future / Aorist Clue | Example |
|---|---|---|
| -άω | η | ἀγαπήσω, ἠγάπησα |
| -έω | η | ποιήσω, ἐποίησα |
| -όω | ω | πληρώσω, ἐπλήρωσα |
Parsing Shortcut 5: Do Not Confuse Contract Indicatives and Subjunctives
Some contract indicative forms resemble subjunctive forms because of long vowels. Context, particles, and accent help identify the form.
| Form | Possible Issue | How to Decide |
|---|---|---|
| ἀγαπῶμεν | Could look like subjunctive | Check context, accent, and whether a subjunctive trigger appears |
| ποιῶμεν | Could be subjunctive or contract indicative depending on context | Look for particles such as ἵνα or ἐάν |
| πληρῶτε | May require context | Check whether statement, command, or purpose clause is present |
Common Student Mistakes
- Failing to recognize ποιῶ as coming from ποιέω.
- Failing to recognize ἀγαπῶ as coming from ἀγαπάω.
- Failing to recognize πληρῶ as coming from πληρόω.
- Assuming every circumflex verb form is automatically subjunctive.
- Confusing contract present forms with future forms.
- Missing lengthened vowels in future and aorist forms.
- Parsing -εῖτε without considering whether it is indicative or imperative.
- Forgetting that contract infinitives may end in -ᾶν, -εῖν, or -οῦν.
- Failing to learn the lexical form together with the contract type.
- Assuming contract verbs are irregular instead of recognizing predictable contraction patterns.
Contract Verb Parsing Flowchart
| Step | Question | What to Look For |
|---|---|---|
| 1 | What is the lexical form? | Check whether it ends in -άω, -έω, or -όω. |
| 2 | Is the form in the present system? | Expect contraction in present, imperfect, present infinitive, and present participle forms. |
| 3 | Is there a circumflex? | A circumflex may signal contraction. |
| 4 | What is the stem? | Identify the lexical root before parsing the ending. |
| 5 | Which contract type is involved? | Alpha, epsilon, or omicron contract. |
| 6 | Is the form future or aorist? | Look for lengthened vowel plus -σ- or -σα-. |
| 7 | Is the form finite, infinitive, or participle? | Check endings such as -εῖν, -ᾶν, -οῦν, -ῶν. |
| 8 | Could the form be confused with a subjunctive? | Check particles, accent, and context. |
| 9 | Confirm the full parsing. | Identify tense-form, voice, mood, person/number or participial case. |

Memorization Strategy for Contract Verbs
Students should memorize contract verbs in three layers.
Layer One: Memorize the Contract Type
- ἀγαπάω = alpha contract
- ποιέω = epsilon contract
- πληρόω = omicron contract
Layer Two: Memorize the Present Active Patterns
| Type | Key Present Active Forms |
|---|---|
| -άω | ἀγαπῶ, ἀγαπᾷς, ἀγαπᾷ, ἀγαπῶμεν, ἀγαπᾶτε, ἀγαπῶσι(ν) |
| -έω | ποιῶ, ποιεῖς, ποιεῖ, ποιοῦμεν, ποιεῖτε, ποιοῦσι(ν) |
| -όω | πληρῶ, πληροῖς, πληροῖ, πληροῦμεν, πληροῦτε, πληροῦσι(ν) |
Layer Three: Memorize Future and Aorist Lengthening
- -άω usually lengthens to η: ἀγαπήσω, ἠγάπησα.
- -έω usually lengthens to η: ποιήσω, ἐποίησα.
- -όω usually lengthens to ω: πληρώσω, ἐπλήρωσα.
Mastering Greek Contract Verb Recognition for Faster Parsing
Greek contract verbs are verbs whose stems end in α, ε, or ο. These vowels contract with the vowels of endings, producing forms that may look unfamiliar at first. The three major types are -άω, -έω, and -όω. Common examples include ἀγαπάω, ποιέω, and πληρόω.
Students who learn to recognize contraction patterns will parse many common New Testament verbs more accurately. The key is to identify the lexical form, notice the contract type, recognize circumflex accents, understand present-system contraction, and remember that future and aorist forms often show lengthened vowels. Once these patterns become familiar, contract verbs cease to be confusing and become one of the most predictable parts of Greek verb morphology.
