Learners guess Hebrew infinitive vowels wrong because they assume there is one prefix, לְ־, and that it never changes. It changes constantly. Ecclesiastes 3:1–8 is the passage that proves it: in seven verses it produces five different vowels under that ל, all of them still live in modern Hebrew, and it runs almost every weak-root class in the language past you while doing it. There is no better naturally occurring drill for the Hebrew infinitive anywhere.
Infinitive syntax — what an infinitive can complement, when it must be used — belongs to the infinitive. This page is about the shapes.
How the text is set
The Hebrew below is the consonantal Masoretic text, checked verse by verse on Sefaria against Miqra according to the Masorah, with a pointed reading line carrying the Masoretic vowels and no cantillation marks. That is classical ktiv haser and not the bare modern ktiv male used elsewhere in this guide — לרחק here, לרחוק today. ׃ is the sof pasuq; ־ is a maqaf.
The frame verse, and a distinction the consonants cannot show
לכל זמן ועת לכל־חפץ תחת השמים׃
lakól zman ve'ét lekhol-khéfets tákhat hashamáyim
For everything there is a season, and a time for every matter under heaven. (Ecclesiastes 3:1)
Read the target line: לכל appears twice, spelled identically. Read the pointed line and they are two different words.
| Pointed | Reads | Made of | Means |
|---|---|---|---|
| לַכֹּל | lakól | לְ + הַ + כֹּל | for the whole of it, for everything |
| לְכׇל־חֵפֶץ | lekhol-khéfets | לְ + כׇל־ (bound, indefinite) | for every matter |
The article has vanished into the ל and left a patach behind — the same swallowing that gives modern בָּעִיר and לַבַּיִת. And in the second phrase the maqaf has shortened כֹּל to כׇל־, which is precisely why modern Hebrew writes כל bound to a noun (כל יום) but הכול standing free. Both facts are unpointed-invisible; both are on the maqaf page.
Two words to keep. עֵת is feminine (Klein glosses it f.n., "time, season, appointed time"), and it is alive: כתב עת is a journal, לעת עתה is "for the time being". חֵפֶץ meant "matter, affair" here and today means "object, article" — the word in חפצים אבודים, lost property.
The arithmetic, because the shape of the passage is the argument
Verses 2 to 8 contain 28 עֵת phrases in 14 antithetical pairs, four to a verse. They are not all built the same way, and the exceptions are the interesting part:
| Shape | How many | Which |
|---|---|---|
| ל + infinitive construct | 23 | the great majority |
| bare infinitive construct, no ל | 3 | סְפוֹד and רְקוֹד (v4), כְּנוֹס (v5) |
| plain noun | 2 | מִלְחָמָה and שָׁלוֹם (v8) |
Of the 23 ל-infinitives, 18 are pa'al, three are pi'el (לְבַקֵּשׁ, לְאַבֵּד, לְדַבֵּר) and two are hif'il (לְהַשְׁלִיךְ, which occurs in verse 5 and again in verse 6). The three bare infinitives are pa'al as well. So the closing pair of the whole poem — "a time of war and a time of peace" — is the one pair with no verb form in it at all, and the poem ends on two nouns.
The five vowels under ל
עת ללדת ועת למות עת לטעת ועת לעקור נטוע׃
et lalédet ve'ét lamút et latá'at ve'ét la'akór natúa
A time to give birth and a time to die, a time to plant and a time to uproot what is planted. (Ecclesiastes 3:2)
עת להרוג ועת לרפוא עת לפרוץ ועת לבנות׃
et laharóg ve'ét lirpó et lifróts ve'ét livnót
A time to kill and a time to heal, a time to break down and a time to build. (Ecclesiastes 3:3)
עת לבכות ועת לשחוק עת ספוד ועת רקוד׃
et livkót ve'ét liskhók et sfod ve'ét rekód
A time to weep and a time to laugh, a time to mourn and a time to dance. (Ecclesiastes 3:4)
עת להשליך אבנים ועת כנוס אבנים עת לחבוק ועת לרחק מחבק׃
et lehashlíkh avaním ve'ét knos avaním et lakhavók ve'ét lirkhók mekhabék
A time to cast away stones and a time to gather stones, a time to embrace and a time to refrain from embracing. (Ecclesiastes 3:5)
עת לבקש ועת לאבד עת לשמור ועת להשליך׃
et levakésh ve'ét le'abéd et lishmór ve'ét lehashlíkh
A time to seek and a time to lose, a time to keep and a time to throw away. (Ecclesiastes 3:6)
עת לקרוע ועת לתפור עת לחשות ועת לדבר׃
et likróa ve'ét litpór et lakhashót ve'ét ledabér
A time to tear and a time to sew, a time to keep silent and a time to speak. (Ecclesiastes 3:7)
עת לאהב ועת לשנא עת מלחמה ועת שלום׃
et le'ehóv ve'ét lisnó et milkhamá ve'ét shalóm
A time to love and a time to hate, a time of war and a time of peace. (Ecclesiastes 3:8)
Line those infinitives up by the vowel under the ל and the system falls out. The vowel on the ל mirrors the first vowel of the bare infinitive stem.
| ל takes | because the stem starts with | In this passage | Modern Hebrew |
|---|---|---|---|
| לִ־ chirik | a vocal shva | לִבְנוֹת · לִשְׁמוֹר · לִתְפּוֹר · לִרְפּוֹא | לִכְתּוֹב · לִסְגּוֹר |
| לָ־ kamatz | a full vowel | לָמוּת · לָלֶדֶת · לָטַעַת | לָשִׁיר · לָקוּם · לָשֶׁבֶת · לָתֵת |
| לַ־ patach | a chataf-patach under a guttural | לַהֲרוֹג · לַעֲקוֹר · לַחֲבוֹק · לַחֲשׁוֹת | לַעֲשׂוֹת · לַעֲבוֹד · לַעֲזוֹר |
| לֶ־ segol | a chataf-segol under א | לֶאֱהֹב | לֶאֱכוֹל · לֶאֱסוֹף |
| לְ־ shva | a pi'el or hif'il stem | לְבַקֵּשׁ · לְאַבֵּד · לְדַבֵּר · לְהַשְׁלִיךְ | לְסַדֵּר · לְהַזְמִין |
A tour of the weak roots, in the order the poem supplies them
Every infinitive above that is not built on a plain strong root is built on a gizra, and this one passage happens to run through most of them. Working out which class a form belongs to is the whole skill of identifying the gizra.
| Form | Root | Class | What it does to the shape |
|---|---|---|---|
| לָלֶדֶת | י־ל־ד | פ״י | first radical drops, ־ֶת ending appears (as in לָשֶׁבֶת) |
| לָמוּת | מ־ו־ת | ע״ו hollow | the middle radical is the vowel |
| לָטַעַת | נ־ט־ע | פ״נ + ל״ג | nun drops; the final guttural pulls the vowel to patach |
| לִבְנוֹת · לִבְכּוֹת · לַחֲשׁוֹת | ב־נ־ה · ב־כ־ה · ח־שׁ־ה | ל״ה | the ה is replaced by the ending ־וֹת |
| לִרְפּוֹא · לִשְׂנֹא | ר־פ־א · שׂ־נ־א | ל״א | the א falls silent — lirpó, lisnó |
| לִקְרוֹעַ | ק־ר־ע | ל״ג | furtive patach before the final ע — likróa |
| לֶאֱהֹב | א־ה־ב | פ״א | chataf-segol on the א, segol on the ל |
Note לָטַעַת in particular: it is a pe-nun root whose first letter is gone entirely, exactly like modern לָתֵת from נ־ת־ן and לָגֶשֶׁת from נ־ג־שׁ, and its third radical is also a guttural, which is what gives it patach where לָגֶשֶׁת has segol. Two weaknesses in one four-letter word.
Words that changed, and one letter that decides a meaning
לִשְׂחוֹק is written with שׂ, sin. The root is שׂ־ח־ק, "to laugh, to play" — Jastrow glosses שָׂחַק as "to be bright; to laugh, jest, play" — and it survives today as the pi'el לְשַׂחֵק, to play a game or a role. With a שׁ instead, שָׁחַק is a different verb entirely, "to rub, grind", and modern לִשְׁחוֹק means to erode. One dot separates them. Modern Hebrew laughs with a third root, צ־ח־ק, in לִצְחוֹק.
הילדים משחקים בחצר, אבל אל תצחק עליהם.
hayeladím mesakhakím bekhatsér, avál al titskhák aleihém
The kids are playing in the yard, but don't laugh at them. (to a man — the two modern roots, one sentence apart)
Three of these infinitives did not survive as everyday verbs, and the honest register labels matter:
- לַחֲשׁוֹת "to be silent" (ח־שׁ־ה, Klein: "to be silent, be inactive") is (Biblical); today you say לִשְׁתּוֹק.
- לִרְחֹק "to be far" is the pa'al of ר־ח־ק, which BDB gives as "to be or become far". Modern Hebrew almost always reaches for the hitpa'el לְהִתְרַחֵק instead, and the pa'al reads (literary).
- לַחֲבוֹק is (literary); the everyday word for hugging is the pi'el לְחַבֵּק — which is exactly what the same verse then supplies in מֵחַבֵּק, מן plus a pi'el participle, "from embracing".
נָטוּעַ is the other participle here: the pa'al passive participle of נ־ט־ע, "planted", built on the same קָטוּל pattern as כָּתוּב and סָגוּר. And כְּנוֹס is a bare pa'al infinitive meaning "to gather"; the root is still central in modern Hebrew — כנס is a conference, לְהִתְכַּנֵּס is to convene — but for gathering up stones you would now say לֶאֱסוֹף.
עדיף שתתרחק מהעניין הזה, זה לא הולך להיגמר טוב.
adíf shetitrakhék meha'inyán hazé, ze lo holékh lehigamér tov
You're better off staying away from this business — it isn't going to end well. (to a man)
Common Mistakes
1. Hunting for the verb that was left out of עֵת לָמוּת. English needs "there is a time to die", and so, as it happens, does modern Hebrew — an Israeli says יש זמן. Nothing has been elided from the verse: עֵת plus an infinitive is already a complete clause, and the classical language simply does not require a verb of existence where the modern one does.
יש זמן לכל דבר, קודם כל תנוח קצת.
yesh zman lekhól davár, kódem kol tanúakh ktsat
There's time for everything — first get some rest. (to a man — the modern clause does need its יש)
2. Reading לָלֶדֶת as a passive. English translations from the King James onward pair "a time to be born" with "a time to die", and that pairing is a translator's choice, not something the Hebrew form says.
❌ ללדת
to be born
Incorrect — לָלֶדֶת is the active pa'al infinitive, to give birth. Hebrew's passive to be born is a different binyan entirely: להיוולד.
3. Back-deriving an irregular infinitive to the wrong root. Strip לָ־ from לָמוּת and you are left with מות, which looks like a two-letter root or invites a doubled one; the same reflex turns לָלֶדֶת into a root beginning with ל.
❌ מ־ת־ת, ל־ד־ת
Incorrect — these are back-formations from the infinitives themselves. The roots are מ־ו־ת, a hollow root whose ו is the vowel, and י־ל־ד, a pe-yod root whose first letter drops out of the infinitive.
4. Assuming every עֵת takes a ל. Three do not, and a reader expecting one will misparse סְפוֹד and רְקוֹד as nouns. The modern verb, incidentally, takes the ordinary chirik.
אין לי זמן לספוד עכשיו, אני צריך לארגן את ההלוויה.
ein li zman lispód akhsháv, aní tsaríkh le'argén et hahalvayá
I have no time to grieve right now, I need to organise the funeral. (m. speaker)
5. Fixing the ל at לְ־. The plain shva is the pi'el and hif'il vowel. Put it on a pa'al stem and you produce a reading no Israeli uses.
❌ לכתוב, לעשות
lekhtóv · le'asót
Incorrect as readings — pa'al takes its vowel from the stem, so these are likhtóv and la'asót. The plain shva belongs to pi'el and hif'il: lesadér, lehazmín.
Key Takeaways
- Verses 2–8 hold 28 עֵת phrases in 14 pairs: 23 with ל plus an infinitive, 3 bare infinitive constructs (סְפוֹד, רְקוֹד, כְּנוֹס), and 2 plain nouns in the closing pair.
- The vowel under ל is not fixed. This passage alone supplies לִ־, לָ־, לַ־, לֶ־ and לְ־, and each one is predicted by the first vowel of the stem that follows. The same five are live in modern Hebrew.
- Of the 23 ל-infinitives, 18 are pa'al, 3 pi'el, 2 hif'il — and every irregular shape traces to a weak-root class: פ״י, ע״ו, פ״נ, ל״ה, ל״א, ל״ג, פ״א.
- עֵת plus an infinitive is a complete clause. Hebrew supplies no verb of existence; the English is has no counterpart to look for.
- לִשְׂחוֹק with sin is "to laugh" (root שׂ־ח־ק, modern לְשַׂחֵק "to play"); לִשְׁחוֹק with shin is "to erode". Read the dot.
- לַחֲשׁוֹת is Biblical, לִרְחֹק and לַחֲבוֹק literary. Recognizing them is the goal; the modern equivalents are לִשְׁתּוֹק, לְהִתְרַחֵק and לְחַבֵּק.
