How a Greek Verb Works

Start with the simplest difference between Greek and English, because everything else in this module grows out of it. An English verb needs help. Believe tells you almost nothing on its own: I believe, you believe, they believe, they believed, they will believe, they would have believed. The work of saying who and when and how is done by separate little words standing around the verb. A Greek verb does most of that work itself, by changing its shape. The ending on the word tells you who is acting and how many, and other pieces of the word tell you more besides.

Here is the present active indicative of πιστεύω (pisteuō, I believe), the verb behind 'believes' in John 3:16, the way a first-year grammar sets it out. πιστεύω, I believe. πιστεύεις (pisteueis), you believe, one person. πιστεύει (pisteuei), he, she or it believes. πιστεύομεν (pisteuomen), we believe. πιστεύετε (pisteuete), you believe, more than one person. πιστεύουσι or πιστεύουσιν (pisteuousi, pisteuousin), they believe. The front of the word, πιστευ-, stays the same. That is the stem, and it carries the meaning of the verb. The end of the word changes. Those are the endings, and they carry person and number.

Read the list again and notice what is missing: there is no word for I, you, he, we or they. Greek can add a pronoun, ἐγώ (egō, I) or σύ (sy, you), but it does not need one, because the ending already says it. When a pronoun does appear in front of a verb, the writer has usually put it there on purpose, often for contrast or emphasis. John 14:3 has ὅπου εἰμὶ ἐγώ (hopou eimi egō, where I am), and the ἐγώ is extra, since εἰμί already means I am. Module 6 will come back to emphasis, and to the danger of finding it everywhere.

So every finite Greek verb, the kind that can stand as the main verb of a sentence, tells you five things. The grammars call them tense, voice, mood, person and number. Person is who: first person is the speaker, second is the one spoken to, third is someone else. Number is singular or plural. Voice is whether the subject acts, is acted upon, or acts with some involvement of itself, active, passive or middle, which is Module 5. Mood is the kind of statement: a statement of fact, a possibility or purpose, a command, a wish. The indicative states, the subjunctive is used for purpose and possibility, the imperative commands, and the optative, rare in the New Testament, wishes. Mood is also Module 5.

Tense is the hard one, and it is the subject of this whole module. For now, notice only that the word is misleading. In English, tense means time: past, present, future. The Greek tense names, present, imperfect, aorist, perfect, pluperfect and future, are labels for families of forms, and what those forms actually signal is one of the liveliest arguments in the study of New Testament Greek. Many grammarians now prefer the word tense-form, to stop us assuming that the label tells us the time. The next lesson lays out that argument. In this lesson, when you see the word aorist, read it as a name for a set of shapes, not yet as a claim about when or how anything happened.

A Greek verb is built from pieces, and once you can see the pieces you can read a tool's parsing with understanding rather than just copying it. The pieces are: sometimes something added to the front, then the stem, then sometimes a marker for the tense-form, then a connecting vowel, then the ending. Not every verb has every piece. You will not be asked to build verbs from scratch in this track. You will be asked to recognise what the tool is pointing at.

Take ἠγάπησεν (ēgapēsen, he loved), the first verb of John 3:16. The dictionary form is ἀγαπάω (agapaō, I love). In ἠγάπησεν the front has changed: the α at the start has become η. That change is called the augment. In most verbs the augment is a little ἐ (e) stuck on the front, as in ἔλυσα (elysa, I loosed) from λύω (lyō, I loose). When the verb already starts with a vowel, the augment lengthens that vowel instead, so α becomes η. The augment appears only in the indicative mood, and only on the aorist, imperfect and pluperfect. What it signals is part of the next lesson's argument; for now, learn to see it.

After the augment comes the stem, ἀγαπη-, where the last vowel has lengthened from α to η, as it regularly does in verbs of this kind before a tense marker. Then the σ (s), the marker of what is called the first aorist. Then the ending -εν (-en), third person singular. Put together: augment, stem, aorist marker, ending. A tool will describe ἠγάπησεν as aorist active indicative, third person singular, of ἀγαπάω, and you can now see where each of those labels lives in the word, except active, which is shown by the ending belonging to the active set.

Not all verbs are so tidy. ἔδωκεν (edōken, he gave), the second verb of John 3:16, comes from δίδωμι (didōmi, I give). It has the augment ἐ, the stem δω-, and then a κ (k) where you might have expected a σ. A handful of very common verbs form their aorist this way, and δίδωμι is one of them. Some verbs change their stem entirely: the aorist of λέγω (legō, I say) is εἶπον (eipon, I said), and John 19:30 has εἶπεν (eipen, he said). The aorist of ἀποθνῄσκω (apothnēskō, I die) is ἀπέθανον (apethanon, I died), which you will meet in lesson 4. You do not have to work these out yourself. This is exactly what the tools are good at, and they will hand you the dictionary form for every word you tap.

That is the last piece worth understanding here. Every Greek dictionary, and every tool, lists a verb under one form, called the lexical form or lemma. For nearly all verbs it is the first person singular present active indicative: πιστεύω, ἀγαπάω, δίδωμι. So when you tap ἔδωκεν and the tool says δίδωμι, it is not giving you a different word; it is telling you where to look the word up. John 3:18, two verses later, has πεπίστευκεν (pepisteuken, he has believed), from the same πιστεύω you met in the paradigm. The front πε- is a doubling of the first consonant, called reduplication, and with the κ before the ending it marks the perfect, which is the subject of lesson 5. Two different shapes, πιστεύων in 3:16 and πεπίστευκεν in 3:18, both looked up under one dictionary entry.

Now read the verse the way the rest of this track will teach you to read every verse, one verb at a time, with the tool open. The SBL Greek New Testament (SBLGNT), which is free to read and download, begins the verse Οὕτως γὰρ ἠγάπησεν ὁ θεὸς τὸν κόσμον (houtōs gar ēgapēsen ho theos ton kosmon, for God so loved the world). The first verb, ἠγάπησεν, you have already taken apart: aorist active indicative, third person singular, of ἀγαπάω. The subject is ὁ θεός (ho theos, God), in the nominative case, and the object is τὸν κόσμον (ton kosmon, the world), in the accusative, which Module 3 taught you to recognise.

The second verb sits inside a clause that begins with ὥστε (hōste, so that): ὥστε τὸν υἱὸν τὸν μονογενῆ ἔδωκεν (hōste ton huion ton monogenē edōken, so that he gave the one and only Son). ἔδωκεν is aorist active indicative, third person singular, of δίδωμι. The mood matters here. When ὥστε is followed by an indicative, as it is here, it states a result that actually happened, not merely one that was intended. God's love did not only aim at the giving; it gave. Within a sentence, ὥστε usually takes an infinitive, and grammarians often point to John 3:16 as one of the less common places where it takes an indicative and so states the result as a fact.

That clause bears on the old question about the little word Οὕτως (houtōs) at the start. English readers usually hear 'so loved' as 'loved so much'. The Greek adverb most often means 'in this way' or 'thus', and a number of recent commentators argue that John is describing the manner of God's love, the way that love showed itself, namely by giving the Son. Others reply that the result clause makes the degree plain anyway, since a love that gives the one and only Son is love of an extraordinary degree, and that English 'so' can comfortably carry both. Both readings are defended by careful scholars. The BSB's 'so loved' keeps the ambiguity open, which is a respectable choice, and you should not preach either reading as if the other did not exist.

The third verb is πιστεύων (pisteuōn, believing), in the phrase πᾶς ὁ πιστεύων εἰς αὐτόν (pas ho pisteuōn eis auton, everyone who believes in him). It is a present active participle, nominative singular masculine, of πιστεύω. A participle is a verb that behaves like an adjective or a noun, which is why it has case, number and gender instead of person: it agrees with πᾶς (pas, everyone) and with the article ὁ (ho, the). Read literally it is 'everyone, the believing one, into him'. The BSB's 'everyone who believes' is the natural English for that construction. Participles get a full lesson in Module 5.

The last two verbs are in a clause of purpose introduced by ἵνα (hina, in order that): ἵνα πᾶς ὁ πιστεύων εἰς αὐτὸν μὴ ἀπόληται ἀλλὰ ἔχῃ ζωὴν αἰώνιον (hina pas ho pisteuōn eis auton mē apolētai alla echē zōēn aiōnion, so that everyone who believes in him should not perish but have eternal life). ἀπόληται (apolētai, he should perish) is aorist middle subjunctive, third person singular, of ἀπόλλυμι (apollymi, to destroy, and in the middle, to perish). ἔχῃ (echē, he should have) is present active subjunctive, third person singular, of ἔχω (echō, I have). Neither is a future. The BSB's 'shall' is the translator's way of carrying the purpose of the ἵνα clause into English, which has no everyday subjunctive left. That is a fair translation, and it is worth knowing that the certainty of the promise rests on who is giving, not on a future tense the Greek does not use.

One more observation, offered with care because the rest of the module is about how much weight such things can bear. The negative clause uses an aorist, perish, and the positive clause uses a present, have. Many readers find that fitting: perishing is viewed as a whole event, having life as an ongoing possession. That may be right. But before you build a sermon on it, notice that ἔχω appears in the present nearly nine times in ten in the New Testament, and its aorist only about twenty times in all. When a verb nearly always takes one form, its appearing in that form tells you less than it would for a verb that could easily have gone either way. Keep that question in your pocket: did the writer have a real choice here? You will need it in every lesson that follows.

In Module 2 you learned what the parsing codes mean. Now use them. In Blue Letter Bible, open John 3:16, tap the verse and choose the interlinear or tools option, then tap the Strong's number beside a Greek word. The page that opens shows the lexical form, the gloss, and the parsing of the form in this verse, set out as words, tense, voice, mood, person, number. In STEP Bible, open the verse with an interlinear view switched on, or tap an English word, and the panel will show the Greek behind it with its grammar spelled out in words, and often with a short code beside it. The menus change from time to time, so if a button has moved, look for the words interlinear, grammar or morphology.

Many tools use a compact code that you met in Module 2. In the scheme drawn up by Maurice Robinson, widely used in free tools, ἠγάπησεν would be V-AAI-3S: verb, aorist, active, indicative, third person, singular. ἔχῃ would be V-PAS-3S: verb, present, active, subjunctive, third person, singular. A participle has a different shape because it has case, number and gender instead of person: πιστεύων would be V-PAP-NSM, verb, present, active, participle, nominative, singular, masculine. Read the code left to right and say each letter aloud as a word. After a week of doing that you will find you no longer need to.

Then check one tool against another, as Module 2 taught. Where two tools disagree, it is usually for one of three reasons. First, they may be printing different Greek texts. Some tools default to the Textus Receptus, the Greek text behind the KJV; others use a modern critical text such as the SBLGNT. In most verses the words are the same, but where they differ, the parsing will differ too, because the word is different. Module 8 deals with that. Second, they may label the same form differently. Verbs such as δύναμαι (dynamai, I am able) have no active forms, and one tool will call them middle, another middle or passive, another deponent, which is an older term for a verb with middle or passive form and active meaning. Those are differences of description, not of fact. Third, the form itself may be ambiguous, and the tool has had to choose.

That third case is the one that matters most, and John 14:1 is the clearest example in the Gospels. Jesus says πιστεύετε εἰς τὸν θεόν, καὶ εἰς ἐμὲ πιστεύετε (pisteuete eis ton theon, kai eis eme pisteuete), using the same form twice. In the present active, the second person plural indicative and the second person plural imperative are spelled exactly alike. So each πιστεύετε could mean 'you believe' or 'believe!'. The KJV reads the first as a statement and the second as a command: 'ye believe in God, believe also in me.' The BSB does the same: 'You believe in God; believe in Me as well.' Others have read both as commands, and some both as statements. One widely used tagging of the SBLGNT labels both as indicative. None of these is a mistake about Greek. Each is a decision about what Jesus is doing in the conversation, and the tool's label is someone's decision printed as if it were a fact.

A parsing tells you what a form is. It does not yet tell you what the sentence means. That distinction will save you from most of the mistakes this module exists to prevent. When a tool tells you that ἠγάπησεν is aorist active indicative, third person singular, it has told you something true and checkable about a word. It has not told you that God loved once, or briefly, or decisively, or for all time. What the aorist contributes to meaning is a separate question, answered by grammar, by the meaning of the verb, and by the context, and lesson 4 is about how often preachers have answered it badly.

So keep two columns in your head, and in a few weeks on paper. In the first column go the facts of form: this is a participle, this is a subjunctive, this is third person plural. Those can be checked and, apart from genuinely ambiguous forms such as πιστεύετε, they are not matters of opinion. In the second column go the judgments of meaning: this participle is giving the reason, this subjunctive expresses purpose, this present describes a habit. Those are often well supported, sometimes debated, and always the reader's responsibility. The danger is not in making judgments. It is in presenting a judgment from the second column with the confidence that belongs to the first, as when a preacher says 'the Greek tense means' and then says something the tense cannot carry.

It also works the other way. Some readers, having learned that a little Greek is dangerous, decide never to say anything about the Greek at all. That throws away the reason for the track. The facts of form are some of the firmest evidence you will ever have about a passage. That 'shall not perish' in John 3:16 is a purpose clause rather than a prediction, that 'believes' is a participle naming a kind of person, that John 14:1 contains a genuine ambiguity the translators had to resolve: these are things an ordinary pastor with a phone can now establish for himself, and his church is better served when he can.

One last caution about vocabulary. The verb in John 3:16 is ἀγαπάω, and you will hear it said that this word names a uniquely divine love, different in kind from every other word for love. Module 7 tests that claim properly. For now, notice only that the same verb is used in John 3:19 of people who loved the darkness rather than the light, and in 2 Timothy 4:10 of Demas, who deserted Paul having loved the present age, where the BSB has 'in his love of this world'. The meaning of the verb in John 3:16 comes from its subject and its object, from who is loving whom and what it cost, and the tool cannot hand you that. The grammar is the floor you stand on, not the whole house.

Turn to the My passage page in your Greek notebook, where you wrote the reference of the passage you chose for your capstone study. If you have not yet settled on one, choose it now: five to twelve verses from a Gospel or a letter that you expect to preach or teach. On the next blank page, draw a table with six columns. Head them: Verse, Greek word, Sound, Dictionary form, Parsing, English in my Bible.

Open your passage in Blue Letter Bible or STEP Bible. Go through it one verse at a time and find every verb, including participles and infinitives. For each one, tap it, and fill in a row: the verse number; the Greek word, copied letter by letter with its accents and breathing; how it sounds, written in English letters; the dictionary form the tool gives; the parsing written out in full words, not in code; and the English word or words your Bible uses for it. If your passage has more than about twenty verbs, do the first half this week and the rest next week.

Then check five of your rows in the second tool. Put a small tick beside each row that agrees. Where the tools disagree, do not choose yet. Write a question mark in the margin and one sentence saying what differs: a different word, a different label for the same thing, or a genuinely different parsing. Finally, look down your English column and circle any English helper words, such as shall, may, let, was or has, that are not separate words in the Greek. Each circle marks a place where the translator has turned a piece of a Greek verb into English, and in the rest of this module you will learn to say why.

Keep this table. Every lesson in this module adds a column to it, and by the end of the module it will be the verb map of your passage, the first major piece of your capstone study.
