שלוש בנות but שלושה בנים. Almost every English-language source explains this by saying the numeral "takes the opposite gender of its noun". That explanation is wrong, it is the reason learners find the teens and the hundreds baffling later on, and this page exists to replace it.
What is actually inverted
The numeral agrees normally — masculine beside a masculine noun, feminine beside a feminine one, exactly like an adjective, with nothing to invert in your head before you speak.
What is inverted is the marking. In this one corner of Hebrew, the suffix that marks the feminine everywhere else marks the masculine, and the bare unsuffixed form is the feminine one. The Academy of the Hebrew Language puts it in a single sentence, in שם המספר – רקע להחלטות האקדמיה (Doron Yaakov, published 29 May 2012; retrieved from a Wayback snapshot of 4 February 2026):
בדרך כלל הסיומת ־ָה מציינת נקבה … ואילו בשם המספר סיומת ־ָה מציינת דווקא את הזכר: שֶׁבַע (נקבה) – שִׁבְעָה (זכר).
Normally the suffix ־ָה marks the feminine … but in the numeral the suffix ־ָה marks specifically the masculine: shéva (feminine) – shiv'á (masculine).
The Academy adds the piece that makes it stop feeling arbitrary: in the numeral system the feminine forms are the base forms — short, unsuffixed, morphologically simple — while the masculine forms are the derived ones. Everywhere else in Hebrew that relationship runs the other way. Nothing here is backwards; you are just looking at a system whose default happens to be feminine.
The domain, exactly
| Range | Marking | Masculine | Feminine |
|---|---|---|---|
| 1 | ordinary | ספר אחד séfer ekhád | מיטה אחת mitá akhát |
| 2 | ordinary | שניים shnáyim | שתיים shtáyim |
| 3–10 | inverted | שלושה shloshá | שלוש shalósh |
| 11–19, unit element | inverted | ארבעה עשר arba'á asár | ארבע עשרה árba esré |
| 11–19, ten element | inverted in its own way | עָשָׂר asár | עֶשְׂרֵה esré |
| 20–90 | none — one form for both | עשרים בנים and עשרים בנות are both correct | |
Three rows are worth stopping on.
The range is 3–19, not 3–10. Sources that stop at ten leave learners stranded at eleven. A teen's unit element behaves exactly like a standalone numeral: ארבעה עשר with a masculine noun, ארבע עשרה with a feminine one.
The ten element inverts too, by a different route. It carries no ־ָה at all: masculine עָשָׂר, feminine עֶשְׂרֵה. The Academy points out the joke in that — עָשָׂר is the form that looks like the feminine ten עֶשֶׂר, עֶשְׂרֵה is the one that looks like the masculine עֲשָׂרָה, and each serves the other gender. The paradigm is drilled on 11–19.
From twenty upward the question disappears. עשרים, שלושים and the rest have no gendered partner, so there is nothing to get wrong. The round numbers are on tens, hundreds and thousands.
Minimal pairs
בקבוצה שלנו ארבע נשים וארבעה גברים.
bakvutsá shelánu árba nashím ve'arba'á gvarím
Our group has four women and four men. (one sentence, both markings)
חיכיתי חמש דקות, לא חמישה ימים.
khikíti khamésh dakót, lo khamishá yamím
I waited five minutes, not five days. (דקה feminine, יום masculine)
גרנו שם עשר שנים ועברנו לפני עשרה חודשים.

We lived there for ten years and moved out ten months ago.
שלושה בנים ובת אחת, וכולם כבר בצבא.
shloshá baním uvát akhát, vekhulám kvar batsavá
Three sons and one daughter, and they're all in the army already. (note אחת follows its noun, unlike everything from two up)
The marking is the easy half
Here is the honest assessment, and it is not what the textbooks imply. Once you have swapped "opposite gender" for "־ָה is masculine", the marking is a five-minute lesson. What costs you months is the other half of the question: is this noun masculine or feminine? Hebrew usually answers that with the singular ending — ־ה and ־ת are feminine — but the plural ending, which is what you are staring at when you count, is unreliable in both directions.
| Feminine nouns with ־ים plurals | Masculine nouns with ־ות plurals |
|---|---|
| שלוש שנים shalósh shaním — three years | שלושה שולחנות shloshá shulkhanót — three tables |
| ארבע מילים árba milím — four words | ארבעה מקומות arba'á mekomót — four places |
| שש ערים shesh arím — six cities | שישה לילות shishá leilót — six nights |
| חמש ביצים khamésh beitsím — five eggs | חמישה חלונות khamishá khalonót — five windows |
Every cell in that table is a place where the plural suffix points one way and the numeral goes the other. There is no rule underneath it and no shortcut to find — the inventory has to be learned noun by noun, and it is worked through on nouns whose plural contradicts their gender.
שלוש שנים למדתי ערבית ושכחתי הכול.

I studied Arabic for three years and forgot the lot.
העברנו שלושה שולחנות למחסן ועדיין אין מקום.
he'evárnu shloshá shulkhanót lamakhsán va'adáyin ein makóm
We moved three tables into the storeroom and there's still no space.
אמרתי לך את זה שבע פעמים והיום זה שוב קרה.
amárti lekhá et ze shéva pe'amím vehayóm ze shuv kará
I've told you this seven times, and today it happened again. (to a man; פעם is feminine, ־ים plural and all)
When the numeral is the only clue
One case makes the point sharper than any drill. מילים is two nouns: the plural of מִילָּה milá, "word", which is feminine, and the plural of מִיל mil, the old unit of distance and the Mandate-era coin, which is masculine. Unpointed — and even pronounced — the two are identical: milím. So the numeral is the only marker left, and it does the whole job:
| Written | Reads | Means |
|---|---|---|
| ארבע מילים | árba milím | four words — feminine, so the bare numeral |
| ארבעה מילים | arba'á milím | four miles — masculine, so the ־ָה numeral |
This is not a constructed puzzle. Searching Hebrew Wikipedia with an insource:/…/ regex query on 16 August 2026, ארבעה מילים returns four hits, and all four are the distance — במרחק ארבעה מילים, "at a distance of four miles". The masculine agreement on מיל is old and consistent: the Mishnah has שְׁלֹשָׁה מִילִין (Yoma 6:8). A learner who reads ארבעה מילים as a gender error has misread the sentence, not caught one.
אמרת ארבע מילים כל הערב, מה קרה?
amárt árba milím kol ha'érev, ma kará?
You said four words all evening — what's wrong? (to a woman)
Do Israelis themselves break this?
Both of the easy answers are wrong, so this one is worth being precise about.
The Academy notes, in the same 2012 paper, that דוברים רבים מתקשים בשימוש הנכון במין הדקדוקי של שם המספר — "many speakers have difficulty using the numeral's grammatical gender correctly" — and immediately adds that the distinction is one of the language's defining features and אין כל כוונה לבטלה, "there is no intention whatsoever of abolishing it". The difficulty is real and officially acknowledged; the agreement is not going anywhere.
In written Hebrew it essentially holds. On the same Wikipedia search, שלוש שנים returns around 12,000 hits — a floor, not an exact count — against one for שלושה שנים, and that single hit sits inside a translated quotation from Josephus. שתי מילים returns 410 against 6 for שני מילים, and reading all six shows that two of them are the masculine מיל again; the remaining four are genuine slips, four against 410.
There is one real colloquial simplification, and it is narrower than learners hope: with currency and measures, casual speech uses the bare numeral and a singular noun — עשר שקל rather than עשרה שקלים. Note the direction. It is the bare form that generalises, never the ־ָה one, so a learner who produces שלושה דקות has not spoken colloquially; they have produced something no register uses. That pattern is annotated in context on at the shuk.
Common Mistakes
1. Applying the counting row to a masculine noun. The bare row is what you learned first, and it is grammatically feminine. This is the error the whole page exists for.
❌ שלוש בנים
Incorrect — בנים is masculine, so the numeral carries ־ָה: שלושה בנים.
✅ שלושה בנים ואף אחד מהם לא עוזר בבית.
shloshá baním ve'áf ekhád mehém lo ozér babáyit
Three sons and not one of them helps around the house.
2. The same error on אנשים. Worth its own line, because people feels genderless in English and the noun is masculine.
❌ ארבע אנשים
Incorrect — אנשים is masculine: ארבעה אנשים. Its feminine counterpart is נשים, which takes ארבע.
✅ ארבעה אנשים חיכו בתור ואף אחד לא ידע למה.
arba'á anashím khikú batór ve'áf ekhád lo yadá láma
Four people were queuing and none of them knew what for.
3. Keying the numeral to a ־ים plural. שנים ends the way masculine plurals end, so the ־ָה form gets pulled across.
❌ שלושה שנים
Incorrect — שנה is feminine and stays feminine in the plural: שלוש שנים. The ־ים ending is not evidence of gender.
✅ שלוש שנים חיכינו לאישור, ובסוף ויתרנו.
shalósh shaním khikínu le'ishúr, uvasóf vitárnu
We waited three years for the permit, and in the end we gave up.
4. Keying the numeral to a ־ות plural. The mirror image, and just as common.
❌ חמש מקומות
Incorrect — מקום is masculine, ־ות plural notwithstanding: חמישה מקומות.
✅ יש עוד חמישה מקומות בהופעה, תזמין עכשיו.
yesh od khamishá mekomót bahofa'á, tazmín akhsháv
There are five places left for the show — book now. (to a man)
5. Reading a correct sentence as an error. Once the rule is internalised, learners start correcting native text that is already right.
❌ ארבעה מילים
four words
Incorrect as 'four words' — with the ־ָה numeral this is four MILES, from the masculine מיל. Four words is ארבע מילים.
✅ הליכה של ארבעה מילים לא נשמעת רחוק עד שעושים אותה.
halikhá shel arba'á milím lo nishmá'at rakhók ad she'osím otá
A four-mile walk doesn't sound far until you do it.
Key Takeaways
- The numeral agrees normally. It is the marking that is inverted: on 3–19 the ־ָה ending marks the masculine and the bare form is feminine. Drop "opposite gender" from your vocabulary.
- The feminine forms are the base forms — that is the whole explanation, and it is the Academy's.
- The domain is precise: 1 and 2 mark gender ordinarily; 3–19 mark it invertedly, teens included; 20–90 do not mark it at all.
- In the teens the ten element inverts too, but by a different route: masculine עָשָׂר, feminine עֶשְׂרֵה.
- The hard part is the noun, not the numeral. Plural endings lie in both directions — שלוש שנים beside שלושה שולחנות.
- ארבע מילים and ארבעה מילים are both correct and mean different things: four words, four miles.
- Edited Hebrew keeps the agreement almost without exception. The one genuine colloquial shortcut — עשר שקל — generalises the bare form only, never the ־ָה one.

- Masculine Nouns Taking ־וֹת, Feminine Taking ־ִיםB1 — A closed list of everyday nouns whose plural ending contradicts their gender — שולחן takes ־וֹת and stays masculine, מילה takes ־ִים and stays feminine. The ending is a fact about the word's shape; the gender is a fact about the word, and every adjective, verb and numeral in the clause follows the gender.
- Getting Number Gender BackwardsA2 — There are two numeral errors, they point in opposite directions, and they come from two beliefs that cannot both be true — which is why fixing one of them so often installs the other. Plus the two places a bare numeral beside a masculine noun is not an error at all, and the counted noun's own number, which learners over-correct once they know the gender rule.
- 1–10 with Masculine Nouns: אחד, שניים, שלושה…A1 — The row nobody counts on their fingers. From three upward it is the ־ָה ending that signals MASCULINE — the reverse of every other agreement pattern in Hebrew — and the masculine nouns that take ־ות plurals are where the error actually happens. Plus the one numeral that looks identical in both genders.
- 1–10 with Feminine Nouns: אחת, שתיים, שלוש…A1 — The row you already half-know from counting aloud is grammatically the feminine set — and almost no course says so. Here it is with its real stress pattern, including the five numerals stressed on the first syllable, and the feminine nouns whose ־ים plurals push learners into the wrong row.
- Grammatical Gender: Every Hebrew Noun Has OneA1 — Every use of a Hebrew noun is masculine or feminine — tables and questions included — and there is no neuter. Gender is not a label on the noun; it is a signal the noun sends to the adjective, the demonstrative and the verb, which is why it cannot be postponed.
- Hebrew Numbers and Why They Have Two GendersA1 — Hebrew has two complete sets of numbers, and the row you learn first — אחת, שתיים, שלוש — is grammatically the feminine one. From three to nineteen the marking runs backwards: the ־ָה ending marks the MASCULINE. One and two mark gender the ordinary way, and twenty to ninety do not mark it at all.
