ב־ or ל־? | Hebrew Grammar

Two single letters carry more of Hebrew than any other words in the language, and English gives you no reliable guide to which is which. The rule in one line: ב־ marks the setting something happens in, ל־ marks the target it is aimed at. Place is only the most obvious application of that; time, money, means and people all fall under it too.

The quick answer, on one noun

Hold the noun still and change nothing but the verb. The preposition follows the verb, not the noun and not the English translation.

Setting — ב־	Target — ל־
אני בבנקbabánk — I'm at the bank	אני הולך לבנקlabánk — I'm going to the bank
נפגשנו בתחנה — we met at the station	הגענו לתחנה — we got to the station
הוא עובד במשרד — he works in the office	הוא נכנס למשרד — he went into the office

אני בבנק עכשיו, אני אחזור אליך עוד עשר דקות.

aní babánk akhsháv, aní akhzór elékha od éser dakót

I'm at the bank right now — I'll get back to you in ten minutes. (to a man)

אני קופץ לבנק ואחר כך אני בא.

aní koféts labánk ve'akhár kakh aní ba

I'm nipping to the bank and then I'll come. (m. speaker)

Which verbs sit on which side, the short lists worth memorising, and the frequent destinations that take neither letter — הביתה, החוצה, ימינה — are worked through on motion versus location. One thing to carry from there: הביתה is not built with ל־ at all. It is a noun plus the directional ־ָה, which does the job of the preposition and refuses to share the word with it; the set is on the directional ־ָה.

Off the map: the jobs that have nothing to do with place

This is where English stops helping, because English switches preposition and Hebrew does not.

Relation	Letter	Example	What English says
point in time	ב־	בשמונה, בשבת, ביוני	at, on, in — three different words
means, tool, vehicle	ב־	באוטובוס, בעט, בטלפון	by, with, on
price	ב־	קניתי במאה שקל	for
manner	ב־	בשקט, בזהירות	-ly — an adverb, not a phrase
recipient	ל־	אמרתי לו, נתתי לדנה	nothing at all — a bare object
beneficiary	ל־	תפסתי לך מקום	for
allotted span of time	ל־	סגרו את הכביש לשבועיים	for

Look at the two for rows and the price row. English spends one word on three unrelated relations and Hebrew splits them across both letters — which is why translating for is the single least reliable move available to you.

קניתי את הכיסא הזה במאה שקל ביד שנייה.

kaníti et hakisé hazé beme'á shékel beyád shniyá

I got this chair for a hundred shekels second-hand.

העברתי לה את הכסף באפליקציה, זה לקח שנייה.

he'evárti la et hakésef ba'aplikátsya, ze lakákh shniyá

I sent her the money on the app — it took a second. (both letters in one sentence: ל־ for the person, ב־ for the means)

תפסתי לך מקום ליד החלון.

tafásti lekhá makóm leyád hakhalón

I grabbed you a seat by the window. (to a man)

💡

One heuristic covers most of the doubt: ל־ is the only one of the two that can point at a person. If the phrase names a human being who receives, benefits or is spoken to, it is ל־ every time — אמרתי לה, עזרתי לו, קניתי לך. ב־ never marks a recipient; the only people who turn up after ב־ are being touched, believed in or looked after, and those are verb-specific governments listed on ב־.

Time is where the split is sharpest

ב־ says when. It is the same letter for the hour, the day and the month, where English uses three (at eight, on Saturday, in June).

ל־ says how long something is set to last — the span allotted to it, not the span it turned out to take. Measured duration, the kind you report afterwards, takes no preposition at all.

הפגישה בעשר, אז תצא בתשע וחצי.

hapgishá be'éser, az tetsé betésha vakhétsi

The meeting's at ten, so leave at half nine. (to a man)

סגרו את הכביש לשבועיים בגלל העבודות.

sagrú et hakvísh lishvu'áyim biglál ha'avodót

They've closed the road for two weeks because of the works. (ל־ — the closure is set to run that long)

גרנו שם שנתיים ואז חזרנו לארץ.

gárnu sham shnatáyim ve'áz khazárnu la'árets

We lived there for two years and then came back. (no preposition at all — this is how long it lasted, not how long it was for)

"Twice a week" against "fifty shekels an hour"

English uses one word, a, for both. Hebrew splits them, and the split is worth measuring rather than asserting. Counting Hebrew Wikipedia with an insource:/…/ regex search on 16 August 2026 — a written register, and the larger figures are floors rather than exact counts:

Events counted inside a period take ב־, and this one is close to absolute: פעמיים בשבוע 404 against פעמיים לשבוע 2; שלוש פעמים ביום 104 against שלוש פעמים ליום 0.
A measured rate leans ל־ but tolerates both: קילומטרים לשעה 165 against קילומטרים בשעה 53; ליטרים לדקה 10 against ליטרים בדקה 5.

So one half of the "per" question has a near-categorical answer and the other half genuinely does not. פעמיים לשבוע is not an error — it is attested, just twice in a corpus that has the other version four hundred times.

אני הולך לבריכה פעמיים בשבוע.

aní holékh labreikhá pa'amáyim bashavúa

I go to the pool twice a week. (m. speaker)

הם משלמים חמישים שקל לשעה, וזה לא מעט.

hem meshalmím khamishím shékel lesha'á, vezé lo me'át

They pay fifty shekels an hour, and that's not bad.

💡

Where a measurement comes back near-categorical, learn the phrase whole; where it comes back mixed, stop worrying about it. פעמיים בשבוע is a chunk to memorise. קילומטר לשעה against קילומטר בשעה is a coin-flip nobody will notice you losing.

One spelling, two words — and it happens to both letters

Both ב־ and ל־ absorb the definite article's ה and keep only its vowel, so at A1 the entire difference between two sentences is a vowel that unpointed Hebrew does not write.

Written	Indefinite reading	Definite reading
בבנק	בְּבַנְק bevánk — in a bank	בַּבַּנְק babánk — in the bank
לבנק	לְבַנְק levánk — to a bank	לַבַּנְק labánk — to the bank
בבניין	בְּבִנְיָין bevinyán — in a building	בַּבִּנְיָין babinyán — in the building

Four letters, four sentences. The mechanism — which vowel appears, and why מ־ behaves differently — is on article fusion, and the writing of the prefix letters themselves is on the prefix letters. The practical consequence for a beginner is narrower and worth stating on its own: a missing ה after ב or ל is not evidence that the noun is indefinite. Most of the time it means the opposite.

הם גרים בבניין ישן בלי מעלית.

hem garím bevinyán yashán bli ma'alít

They live in an old building with no lift. (bevinyán — indefinite)

חכה לי בבניין, אני עולה עוד רגע.

haké li babinyán, aní olé od réga

Wait for me in the building — I'm coming up in a second. (to a man, m. speaker; babinyán — the same four letters, definite)

Common Mistakes

1. Translating English into with ב. The English word contains in, so ב־ looks like the obvious choice. נכנס is a motion verb and takes ל־; Hebrew Wikipedia has נכנס לחדר 291 times and נכנס בחדר not once.

❌ נכנסתי בחדר וכולם הפסיקו לדבר

Incorrect — נכנס points at where you are heading, with ל־: נכנסתי לחדר. ב־ would say you were already inside.

✅ נכנסתי לחדר וכולם הפסיקו לדבר.

nikhnásti lakhéder vekhulám hifsíku ledabér

I walked into the room and everyone stopped talking.

2. Marking a span of time with ב. English for two weeks has no in in it, so this one comes from over-applying ב־ to everything temporal.

❌ נסענו לאיטליה בשבועיים

Incorrect as 'we went to Italy for two weeks' — an allotted span takes ל־: נסענו לאיטליה לשבועיים. בשבועיים would mean 'within two weeks'.

✅ נסענו לאיטליה לשבועיים וחזרנו שרופים.

nasánu le'itálya lishvu'áyim vekhazárnu srufím

We went to Italy for two weeks and came back sunburnt.

3. Waiting for someone with בשביל. English wait for pushes you towards the word that means for, and חיכה governs ל־.

❌ אני מחכה בשבילך למטה

Incorrect as 'I'm waiting for you' — חיכה takes ל־: אני מחכה לך למטה. בשביל is 'on behalf of', so this says you are doing someone else's waiting for them.

✅ אני מחכה לך למטה, תרד כשאתה מוכן.

aní mekhaké lekhá lemáta, teréd kshe'atá mukhán

I'm waiting for you downstairs — come down when you're ready. (to a man, m. speaker)

4. Writing the article back in after the fusion. You can hear the a of the article, so you reach for the letter that usually carries it.

❌ בההתחלה זה נראה קשה

Incorrect as a spelling — ב absorbs the article's ה and keeps only its vowel. It is written בהתחלה and read bahatkhalá, with one ה, not two.

✅ בהתחלה זה נראה קשה, אחרי שבוע זה הלך מעצמו.

bahatkhalá ze nir'á kashé, akharéi shavúa ze halákh me'atsmó

At first it looked hard; after a week it went by itself.

Key Takeaways

ב־ is the setting, ל־ is the target. Place is only the most visible case: time, means, price and manner are all settings; destinations, recipients, beneficiaries and allotted spans are all targets.
In a sentence about place, the verb decides — the lists are on motion versus location, and הביתה takes the directional ־ָה instead of ל־ altogether.
English for is the least reliable word to translate: price is ב־ (במאה שקל), beneficiary is ל־ (תפסתי לך), duration is ל־ (לשבועיים), and wait for is ל־ as well.
Time: ב־ for when, ל־ for how long it is meant to last, and a bare noun phrase for how long it actually took — הפגישה בעשר, סגרו לשבועיים, גרנו שם שנתיים.
On "per", the measurement splits: פעמיים בשבוע is near-categorical (404 : 2 in one written corpus), while קילומטר לשעה / בשעה is genuinely mixed (165 : 53).
Both letters swallow the article, so בבנק is bevánk or babánk and לבנק is levánk or labánk. A missing ה is not evidence of an indefinite noun — see article fusion.
Price, instrument and the עם/ב־ split get their full treatment on ב־ of price and means; the dative and the verbs that demand it are on ל־.
