Hebrew has a noun class that courses teach word by word and almost never name. Its members are among the first hundred words you learn — סֵפֶר, יֶלֶד, מֶלֶךְ, בּוֹקֶר, דֶּרֶךְ — and every one of them does the same violent thing in the plural. Learn them as separate irregularities and you have a dozen facts; learn them as a class and you have one.
What makes a noun a segolate
A segolate is a two-syllable noun stressed on the first syllable — מִלְעֵיל — which is already remarkable, because Hebrew otherwise stresses the last. The name comes from the סֶגוֹל that usually fills the second syllable.
The reason for both facts is historical and worth thirty seconds. These words were originally one syllable: safr, yald, bukr. Hebrew does not tolerate that final cluster, so it broke it open with a helping vowel — a segol — before the last consonant, and the stress stayed on the original vowel, which is now the first syllable.
That single fact predicts the whole plural. The helping vowel was never part of the word, so once a suffix arrives there is no cluster to break up and it simply does not appear. What surfaces instead is the original base plus the ending, reshaped as קְטָלִים — or קְטָלוֹת in the few that take the other suffix, like אֲרָצוֹת.
קניתי ספר אחד ויצאתי מהחנות עם ארבעה ספרים.
kaníti séfer ekhád veyatsáti mehakhanút im arba'á sfarím
I went in for one book and came out with four.
הילדים כבר ישנים, אפשר לדבר בשקט?
hayeladím kvar yeshením, efshár ledabér beshéket?
The kids are asleep already — can we talk quietly?
Three subtypes, by the vowel that was there first
The segol in the second syllable is the same in all of them. What separates the subtypes is the vowel in the first syllable, which is the word's original one.
| Type | Singular | Plural | Meaning |
|---|---|---|---|
| a-type | יֶלֶד yéled | יְלָדִים yeladím | child |
| כֶּלֶב kélev | כְּלָבִים klavím | dog | |
| מֶלֶךְ mélekh | מְלָכִים melakhím | king | |
| e-type | סֵפֶר séfer | סְפָרִים sfarím | book |
| עֵמֶק émek | עֲמָקִים amakím | valley | |
| שֵׁבֶט shévet | שְׁבָטִים shvatím | tribe | |
| o-type | בּוֹקֶר bóker | בְּקָרִים bkarím | morning |
| חוֹדֶשׁ khódesh | חוֹדָשִׁים khodashím | month | |
| אוֹהֶל óhel | אוֹהָלִים ohalím | tent |
The o-type rows disagree with each other, and the reason is not the noun. בְּקָרִים loses its o; חוֹדָשִׁים and אוֹהָלִים keep it. The difference is the first letter: ח and א are gutturals, and a guttural cannot carry a bare shva, so it takes a chataf-kamatz — a half-vowel that preserves the o colour. This shows up in writing too, because that surviving o is written with a ו and the vanished one is not: חודשים has a vav and בקרים does not.
בבקרים אני לא מסוגל לדבר עם אף אחד.
babkarím aní lo mesugál ledabér im af ekhád
In the mornings I can't manage to talk to anybody. (m. speaker)
עברו כמה חודשים עד שהוא ענה לי.
avrú káma khodashím ad shehú aná li
Months went by before he answered me.
The guttural members take patach, not segol
When the second or third letter is ח, ע or ה, the segol is replaced by a patach — the same vowel a guttural always prefers. These are still segolates in every way that matters: same stress, same plural.
| Singular | Plural | Meaning |
|---|---|---|
| פַּעַם pá'am | פְּעָמִים pe'amím | time, occasion |
| נַעַר ná'ar | נְעָרִים ne'arím | youth, lad |
| שַׁעַר shá'ar | שְׁעָרִים she'arím | gate |
| רֶגַע réga | רְגָעִים rega'ím | moment |
| זֶרַע zéra | זְרָעִים zra'ím | seed |
A first-letter guttural turns the plural's shva into a chataf instead: חֶדֶר gives חֲדָרִים, אֶרֶץ gives אֲרָצוֹת.
הדירה קטנה, שני חדרים ומטבח.
hadirá ktaná, shnei khadarím umitbákh
The flat's small — two rooms and a kitchen.
הוא עבד בשלוש ארצות לפני שחזר לארץ.
hu avád beshalósh aratsót lifnéi shekhazár la'árets
He worked in three countries before coming back to Israel.
The plural is a different stem, not a modified one
This is the sentence to take away. On stem changes in the plural a vowel weakens under stress pressure and the word stays recognisable. Here the entire vowel pattern is replaced: the original vowel and the helping segol are both gone, ־ָ־ arrives before the last consonant, and the stress moves to the suffix.
So séfer and sfarím share not one vowel and not one stressed syllable — and in unpointed writing they are ספר and ספרים, the same three letters with an ending. That is the whole reason a page can look transparent and sound unrecognisable.
יש לשכנים שני כלבים והם נובחים כל הלילה.
yesh lashkhením shnei klavím vehém novkhím kol haláyla
The neighbours have two dogs and they bark all night.
היא כתבה עבודה על המלכים של יהודה.
hi katvá avodá al hamelakhím shel yehudá
She wrote a paper on the kings of Judah.
The shape says nothing about gender
A segolate looks unmarked, and learners read that as masculine. Several of the commonest are feminine: דֶּרֶךְ, אֶבֶן, פַּעַם, נֶפֶשׁ — and three of those four take ־ִים as well (דְּרָכִים, אֲבָנִים, פְּעָמִים), so the noun looks masculine twice over and agrees feminine anyway. That collision is on mismatched plurals, and the wider list of unmarked feminines on nouns whose gender contradicts their ending.
שתי הדרכים מגיעות לאותו מקום, אחת פשוט ארוכה יותר.
shtei hadrakhím magi'ót le'otó makóm, akhát pashút aruká yotér
Both roads get to the same place, one's just longer.
In the construct, two different stories
The construct singular is normally unchanged: סֵפֶר־, מֶלֶךְ־, יֶלֶד־, כֶּלֶב־, בּוֹקֶר־. A short lexical group does shift, and the one you will use is חֲדַר khadár, as in חֲדַר שֵׁינָה. It is tempting to write that as "first-guttural segolates shift", and Hebrew hands you two counter-examples every learner already knows: אֶרֶץ יִשְׂרָאֵל and עֶרֶב שַׁבָּת are first-guttural segolates that do not shift at all. Learn חֲדַר as an item; the full account is on how the first noun changes.
The construct plural is a genuinely separate shape, and it tracks the subtype above: the a-type gives קַטְלֵי — יַלְדֵי yaldéi, מַלְכֵי malkhéi, כַּלְבֵי kalvéi — while the e-type gives קִטְלֵי, סִפְרֵי sifréi and שִׁבְטֵי shivtéi. The working is on plural in construct.
The reading skill this buys you
Meet פְּסָלִים in a text and you cannot look it up: dictionaries list פֶּסֶל. So run the pattern backwards. A plural of the shape C-CaCím is almost always a segolate; put the stress back on the first syllable, drop the a, and insert a segol before the last consonant. psalím gives pésel, shvatím gives shévet, ksafím gives késef. The method for supplying vowels you cannot see is on reading unpointed Hebrew.
בכיכר הזאת יש שני פסלים שאף אחד לא מבין.
bakikár hazót yesh shnei psalím she'áf ekhád lo mevín
There are two statues in that square that nobody understands.
Common Mistakes
1. Building the plural on the singular you know. The commonest error by a distance, because every other Hebrew plural lets you keep most of the word.
❌ ילדים
yéledim
Incorrect as a pronunciation — the plural replaces the whole vowel pattern and moves the stress to the ending: yeladím. Likewise sfarím, klavím, melakhím — never séferim or kélevim.
✅ בגן שלה יש עשרים ילדים ורק שתי גננות.
bagán shelá yesh esrím yeladím verák shtei gananót
There are twenty children in her nursery and only two teachers.
2. Carrying the singular's ו into the plural. An o-type segolate spells its o with a vav, and when the o disappears the vav goes with it.
❌ בוקרים
Incorrect as the plural of בוקר — the o is gone, so the vav is too: בקרים, bkarím. (בּוֹקְרִים is a real word, meaning cattlemen.) Contrast חודשים, which keeps its vav because the guttural ח holds the o as a chataf.
✅ קיפלנו את האוהלים לפני שהתחיל לרדת גשם.
kipálnu et ha'ohalím lifnéi shehitkhíl larédet géshem
We folded up the tents before it started to rain.
3. Reading the shape as masculine. Nothing marks these nouns feminine, so the default fires and the adjective comes out wrong.
❌ אבן גדול
Incorrect — אבן is feminine: אבן גדולה. So are דרך, פעם and נפש, none of which carries a feminine marker.
✅ מצאתי אבן גדולה בגינה, אין לי מושג מאיפה היא.
matsáti éven gdolá baginá, ein li muság me'eifó hi
I found a big stone in the garden — I've no idea where it came from.
4. Running the pattern backwards without restoring the segol. Learners who meet the plural first invent a singular by chopping the ending off.
❌ כלב
klav
Incorrect as a pronunciation — the plural klavím comes from kélev, with the stress on the first syllable. The plural's stem never appears in the singular.
✅ הכלב שלהם ענק אבל הוא הכי פחדן שיש.
hakélev shelahém anák avál hu hakhí pakhdán sheyésh
Their dog is enormous but he's the biggest coward going.
Key Takeaways
- A segolate is a two-syllable noun stressed on the first syllable, against Hebrew's ordinary final stress. The second vowel is a helping vowel that was never part of the word.
- Three subtypes, by the original first vowel: a-type יֶלֶד, e-type סֵפֶר, o-type בּוֹקֶר. A ח, ע or ה as the second or third letter swaps the segol for a patach: פַּעַם, נַעַר, רֶגַע.
- The plural is a different stem, קְטָלִים, with the stress on the suffix — which is why séfer and sfarím share no vowel and yet are ספר and ספרים on the page.
- An o-type keeps its o only behind a guttural: חוֹדָשִׁים and אוֹהָלִים keep the vav, בְּקָרִים does not.
- The shape says nothing about gender: דרך, אבן, פעם and נפש are feminine, and three of those four take ־ִים on top of it.
- The construct singular is normally unchanged (סֵפֶר־, מֶלֶךְ־); חֲדַר is a lexical item, not a guttural rule — אֶרֶץ יִשְׂרָאֵל and עֶרֶב שַׁבָּת prove it. The construct plural is its own shape, and it tracks the subtype: יַלְדֵי against סִפְרֵי.
- To look a plural up, run the pattern backwards: psalím gives pésel, and פֶּסֶל is the entry.
Related Topics
- Stem Changes in the PluralB1 — Adding a stressed ־ִים or ־וֹת strands the noun's first vowel two syllables from the accent, and it starves: דָּבָר becomes דְּבָרִים, מָקוֹם becomes מְקוֹמוֹת. One phonological principle predicts most of it, a second class changes a consonant instead of a vowel, and none of it shows up in unpointed writing — which is why a learner can know a word and still not be understood saying its plural.
- Stress: מלרע vs מלעילA1 — Hebrew stresses the last syllable of a word — shalóm, todá, slichá — and English speakers get this wrong more audibly than any consonant. Here is the default, the four pockets where the stress moves back, and why this guide prints an accent on every romanization.
- Adjectives with Shifting Vowels: קטן, לבן, ישןB1 — קָטָן becomes קְטַנָּה and קְטַנִּים — the first vowel does not weaken, it disappears, and the word starts with a consonant cluster: ktaná, ktaním. Nothing in the unpointed spelling shows it, which is why saying kataním is one of the most persistent giveaways of a foreign accent in Hebrew.
- Reading Unpointed Hebrew: Supplying the Vowels YourselfA2 — Unpointed Hebrew is not pointed Hebrew with the dots rubbed out — it is read by a different method, in which the reader supplies the vowels from the word, the pattern and the sentence. Here is that method, step by step.
- Plural in Construct: בתים → בתי, ילדים → ילדיB1 — In the plural, the two genders stop behaving alike. Masculine ־ִים is replaced by ־ֵי and the stem usually shifts with it — בתים gives בתי, ילדים gives ילדי. Feminine ־וֹת keeps its ending, which learners read as 'not construct'; it is construct, and its stem can still change underneath.
