Hebrew's main device for making a compound is to put two nouns next to each other and add nothing at all — no of, no 's, no preposition, no hyphen required. בית ספר is a school, מיץ תפוזים is orange juice, יום הולדת is a birthday. The construction is called סמיכות smichut, and it is not a corner of the grammar you can leave until later: it is how Hebrew builds vocabulary, so you will meet a dozen chains before you have finished your first conversation.
Two nouns, no glue
A chain has two named slots, and can hold more members than two, and they have names worth learning because every later page uses them.
| Slot | Name | In בית ספר | What it does |
|---|---|---|---|
| first | נִסְמָךְnismákh | בית | the head — it is what the thing is, and it may change shape |
| second | סוֹמֵךְsomékh | ספר | the modifier — it narrows the head, and it carries definiteness for both |
The names are a picture of the relationship. נסמך is a passive participle, "the leaned one"; סומך is active, "the one supporting". The first word leans on the second, and — as you will hear the moment you say the phrase out loud — it cannot stand up without it.
בסוף מצאנו בית ספר טוב עשר דקות מהבית.
basóf matsánu beit séfer tov éser dakót mehabáyit
In the end we found a good school ten minutes from home.
יש מיץ תפוזים במקרר, תשתה כמה שאתה רוצה.
yesh mits tapuzím bamekarér, tishté káma she'atá rotsé
There's orange juice in the fridge — have as much as you want. (to a man)
Read it backwards: the head comes first
This is where beginners actually break, and it happens before any of the morphology does. English builds a compound by stacking modifiers in front of the head noun: orange juice is a kind of juice, and juice comes last. Hebrew does the reverse. The head comes first, and everything that narrows it follows.
So a Hebrew chain reads like an English of-phrase turned inside out. Take six ordinary English compounds and flip each one:
| English | Hebrew | Word for word |
|---|---|---|
| orange juice | מיץ תפוזים mits tapuzím | juice of-oranges |
| train station | תחנת רכבת takhanát rakévet | station of-train |
| phone number | מספר טלפון mispár télefon | number of-telephone |
| bedroom | חדר שינה khadár sheiná | room of-sleeping |
| homework | שיעורי בית shi'uréi báyit | lessons of-home |
| birthday | יום הולדת yom hulédet | day of-birth |
The practical instruction is: say the category first. If you are reaching for "chocolate cake", start with עוגה. If you are reaching for "bus stop", start with תחנה. A learner who translates the English compound left to right produces תפוזים מיץ and then wonders why nobody understands, because the two words have swapped jobs — the first slot is the head, so תפוזים מיץ is an oranges-of-juice, whatever that would be.
ביקשו ממני מספר טלפון ולא היה לי מה לתת.
bikshú miméni mispár télefon veló hayá li ma latét
They asked me for a phone number and I had nothing to give them.
הדירה קטנה: חדר שינה אחד, סלון ומטבח.
hadirá ktaná: khadár sheiná ekhád, salón umitbákh
The flat is small: one bedroom, a living room and a kitchen.
הילדים עושים שיעורי בית עד שמונה בערב.
hayeladím osím shi'uréi báyit ad shmóne ba'érev
The kids do homework until eight in the evening.
The inventory you already half-know
Most of the chains a beginner needs are not built on the spot; they are lexical items you learn whole, the way you learn bus stop rather than assembling it. Here is the everyday core:
| Chain | Reads | Means |
|---|---|---|
| בית ספר | beit séfer | a school |
| עוגת שוקולד | ugát shokolád | a chocolate cake |
| מספר טלפון | mispár télefon | a phone number |
| תחנת רכבת | takhanát rakévet | a railway station |
| יום הולדת | yom hulédet | a birthday |
| שיעורי בית | shi'uréi báyit | homework |
| חדר שינה | khadár sheiná | a bedroom |
| מיץ תפוזים | mits tapuzím | orange juice |
הבאתי עוגת שוקולד למשרד ותוך רבע שעה לא נשאר ממנה כלום.
hevéti ugát shokolád lamisrád vetókh réva sha'á lo nish'ár miména klum
I brought a chocolate cake to the office and within a quarter of an hour there was nothing left of it.
מחר יום הולדת לאבא שלי ועוד לא קניתי כלום.
makhár yom hulédet le'ába shelí ve'ód lo kaníti klum
It's my dad's birthday tomorrow and I still haven't bought anything.
Three things follow from the welding
Because the two nouns are welded into one unit, three rules fall out. Each has its own page; this is the map.
1. The first noun changes shape. בַּיִת "house" appears in a chain as בֵּית, מִשְׁפָּחָה "family" as מִשְׁפַּחַת, עוּגָה "cake" as עוּגַת. The bound form is called the construct form, and it is a real morphological change, not a spelling convention — you can hear it. That is how the first noun changes, with the plural half on plural in construct.
2. The article goes on the second noun, and makes the whole chain definite. A school is בית ספר; the school is בית הספר — one ה, on the back word. Never on the front one, and never on both. That is definiteness in a chain.
3. Nothing may come between the two nouns. An adjective describing the chain has to wait until the chain has finished, and then it agrees with the head — עוגת שוקולד טעימה, feminine because עוגה is feminine, never mind the masculine שוקולד sitting next to it. That is where the adjective goes, and the general position rule is on adjectives come after the noun.
הם בנו תחנת רכבת חדשה ופתאום כולם רוצים לגור פה.
hem banú takhanát rakévet khadashá ufit'óm kulám rotsím lagúr po
They built a new railway station and suddenly everybody wants to live here. (חדשה agrees with תחנה, the head — not with רכבת)
One word, for the purposes of stress
A chain is not just two words that happen to be adjacent. It is a single stress unit: the נסמך gives up its own main accent and leans on the סומך, so בית ספר comes out as one prosodic word, beit-séfer, with a single main beat at the end. This is not a modern innovation — in pointed classical texts the two words are physically joined by a maqaf, בֵּית־סֵפֶר, and the joined word carries no accent of its own. That mechanism, and where the mark is still written today, is on the מקף and hyphenated prefixes.
אני צריך לקפוץ לבית מרקחת לפני שהם סוגרים.
aní tsaríkh likfóts levéit mirkákhat lifnéi shehém sogrím
I need to nip to a pharmacy before they close. (m. speaker)
Two useful things follow from the prosody. First, it explains why a chain feels like a single word to a native speaker, and therefore why so many chains have drifted into being one — כדורגל football was once כדור־רגל, "ball of foot". Second, it explains a very common feature of speech: because Israelis process בית ספר as one word, they will often stick the article on the front of the whole thing and say הבית ספר. That is documented colloquial Israeli, not a foreigner's error, and it is handled properly on definiteness in a chain.
When not to build one
Hebrew has a second way of joining two nouns — של — and reaching for chains everywhere is as wrong as never building one. The short version is that a chain names a kind of thing (בית ספר, כרטיס אשראי, מדפסת לייזר) while של says who this particular item belongs to (הספר של דני). That trade-off is worked out, with the corpus evidence behind it, on סמיכות or של? — and it is genuinely settled there, so this page will not re-argue it.
Common Mistakes
1. Putting a linking word between the two nouns. Every English of asks for a של, and inside a compound it does not belong.
❌ מיץ של תפוזים
Incorrect — a chain takes nothing at all between its two nouns: מיץ תפוזים. When a pair of nouns genuinely can go either way, the choice is a real one; where Hebrew has a compound, של is not an option.
✅ קניתי מיץ תפוזים ולימונדה לילדים.
kaníti mits tapuzím velimonáda layeladím
I bought orange juice and lemonade for the kids.
2. English order, straight through. The compound arrives in your head as one English unit and comes out with the words in the English sequence.
❌ טלפון מספר
Incorrect as 'a phone number' — the head noun goes first, so it is מספר טלפון, literally 'number of telephone'. As written you have built the opposite chain, something like 'a number's telephone'.
✅ תשמור את מספר הטלפון שלי, אני זמין כל היום.
tishmór et mispár hatélefon shelí, aní zamín kol hayóm
Keep my phone number — I'm around all day. (to a man)
3. Slipping an adjective inside the chain. You want the adjective to describe the first noun, so you put it straight after the first noun — and split the compound in half.
❌ מיץ טרי תפוזים
Incorrect — nothing may stand between the members of a chain, not even a word that describes the first noun. The adjective goes after the whole chain: מיץ תפוזים טרי.
✅ הם סוחטים מיץ תפוזים טרי בכניסה לשוק.
hem sokhatím mits tapuzím tarí baknisá lashúk
They squeeze fresh orange juice at the market entrance.
4. Turning every English compound into a chain. The construction is productive, which makes it tempting — but Hebrew often names a category with an adjective instead, and nationalities almost always are.
❌ מסעדת סין
Incorrect as 'a Chinese restaurant' — nationality is an adjective in Hebrew: מסעדה סינית. Built as a chain it would say 'a restaurant of China', which is not how the category is named.
✅ יש מסעדה סינית טובה בפינה, אבל צריך להזמין מקום.
yesh mis'adá sinít tová bapiná, avál tsaríkh lehazmín makóm
There's a good Chinese restaurant on the corner, but you have to book.
Key Takeaways
- A construct chain is two nouns with nothing between them: בית ספר, מיץ תפוזים, יום הולדת. No of, no 's, no preposition.
- The slots have names: the first is the נסמך, the head, and the second is the סומך, the modifier that narrows it and carries definiteness for the pair.
- The order is the reverse of English. Hebrew names the category first — juice of-oranges, station of-train, day of-birth. Say the category first and the rest follows.
- Three consequences, each with its own page: the first noun changes shape, the article goes on the second noun only, and an adjective waits for the whole chain and agrees with whichever noun it modifies.
- A chain is one stress unit — beit-séfer — which is why classical pointed texts join it with a maqaf, why compounds fuse into single words (כדור־רגל to כדורגל), and why Israelis casually say הבית ספר in speech.
- Reach for a chain when the pair would make a good sign or dictionary entry; reach for של when you are saying who owns this particular item.

- How the First Noun Changes (בית → בית־, מלכה → מלכת־)A2 — The first word of a construct chain is not the dictionary word. Masculine nouns either sit unchanged or shorten a vowel; every feminine noun in ־ָה swaps it for a fully audible ־ַת — עוגה becomes עוגת, מלכה becomes מלכת. This page is that morphology, pointed, plus the segolates that look like exceptions and the one group that really is.
- Definiteness in a Chain: בית הספר, Never הבית הספרA2 — One ה, on the last noun, and the whole chain is definite. English marks a phrase at the front and Hebrew marks it at the back, which is why this is the most-corrected construct-chain error there is — and why three further things follow from it: את, the article on the adjective, and the fact that a chain cannot be half definite.
- Where the Adjective Goes in a Construct ChainB1 — Two rules: the adjective waits until the whole chain has finished, and it agrees with whichever noun it describes. Since it cannot move, agreement is the only signal of what it attaches to — דלת הבית הכחולה is the blue door, דלת הבית הכחול is the blue house's door. And when the two nouns match in gender and number, Hebrew simply cannot tell you.
- סמיכות or של?B1 — One question decides it: are these two nouns naming a KIND of thing, or is the second one an owner? A construct chain names a kind — בית ספר, עוגת שוקולד, תחנת רכבת — and של says who this particular item belongs to. Everything else on this page is that test, run out loud on the cases where it is not obvious.
- Frozen Compounds: בית ספר, עורך דין, כדורגלB1 — Most of the chains you will ever use are not built on the spot — they are single lexical items that happen to be spelled as two words. Two tests identify them: nothing can be pushed between the members, and the meaning is not the sum of the parts. Some finish the journey and fuse into one word.
- Compounds: סמיכות, Hyphenated Forms and BlendsB2 — Distinguish Hebrew's three compound structures and predict where the article and plural marking will appear.
