אם: If and Whether | Hebrew Grammar

אם is two different words wearing the same spelling. One opens a condition — if it rains, we'll stay in. The other embeds a yes-no question — ask him if he's coming — where nothing conditional is happening at all. English fuses them into a single if as well, which is exactly why learners never notice the join and then get stuck hunting for a separate Hebrew word for whether. There isn't one. This page is the conjunction; the conditional system proper is on real conditionals, and the syntax of embedded questions on indirect questions.

Job one: the condition

אם heads an open condition — something that may or may not happen. For a future event, Hebrew puts a future verb in both halves, where English forbids its own future and substitutes a present.

אם תבוא בשמונה נספיק לאכול לפני ההצגה.

im tavó bishmóne naspík le'ekhól lifnéi hahatsagá

If you come at eight we'll have time to eat before the show. (to a man)

אם לא נמצא חנייה, נחנה ברחוב הבא ונלך ברגל.

im lo nimtsá khanayá, nakhané barekhóv habá venelékh barégel

If we don't find a parking space, we'll park in the next street and walk.

That is the whole of it for the purposes of this page — the three tense patterns, the אז that opens the main clause in speech, and the comma rules are worked out on real conditionals.

Job two: whether

After verbs of asking, knowing, checking and wondering, אם embeds a yes-no question. Nothing is being made conditional on anything; אם is simply naming an open question.

שאלתי אותו אם הוא מכיר מישהו שמוכר מקרר יד שנייה.

sha'álti otó im hu makír míshehu shemokhér mekarér yad shniyá

I asked him whether he knows anyone selling a second-hand fridge.

תבדקי אם הסניף פתוח בערב ראש השנה.

tivdekí im hasníf patúakh be'érev rosh hashaná

Check whether the branch is open on the eve of Rosh Hashanah. (to a woman)

אני לא בטוח אם זו הכתובת הנכונה.

aní lo batúakh im zo haktóvet hanekhoná

I'm not sure whether this is the right address. (m. speaker)

The verbs that open an אם clause of this second kind are a recognisable set — שאל, ידע, בדק, זכר, בירר, התלבט, and the predicates לא בטוח and מעניין — and what they have in common is that each of them leaves an answer open. Hebrew also has a fixed frame for covering both branches at once rather than asking about them: בין אם … ובין אם.

בין אם תבוא ובין אם לא, אני מזמין מקום לארבעה.

bein im tavó uvéin im lo, aní mazmín makóm le'arba'á

Whether you come or not, I'm booking a table for four. (to a man, m. speaker)

💡

A one-second test that separates the two senses. Try inserting או לא ("or not") at the end of the clause. If the sentence survives — תבדקי אם הסניף פתוח או לא — it is whether. If it collapses, it is a condition. The reverse test also works: a condition accepts אז in front of the main clause, and an embedded question does not.

אם against האם

They share two letters and do not share a job. האם opens a direct yes-no question and belongs to writing — a form, an official email, an interview transcript. אם embeds one. Putting אם at the head of a direct question does not produce a question at all, and putting האם into an embedded one is the point the Academy of the Hebrew Language rules on explicitly: in an indirect question one writes אם, not האם.

האם קיבלת את המסמכים ששלחנו בשבוע שעבר?

ha'ím kibálta et hamismakhím sheshalákhnu bashavúa she'avár?

Did you receive the documents we sent last week? (to a man — formal written; in speech this is just קיבלת את המסמכים?)

לא הודעת לי אם קיבלת את המסמכים.

lo hodáta li im kibálta et hamismakhím

You didn't let me know whether you'd received the documents. (to a man — embedded, so אם)

The honest footnote is that embedded האם is nonetheless everywhere in written Hebrew — השאלה האם, לבדוק האם — and the counts that establish it are on reporting questions and commands. Read the Academy's position as a recommendation for careful writing set against real usage, not as a verdict that half the press is ungrammatical. In speech, none of this arises: nobody says האם.

אם against כש־

אם leaves the event open; כש־ takes the event for granted and leaves only the timing open. אם אסיים היום means I may well not; כשאסיים היום means I will, and we are discussing when. Nothing else in the sentence carries that difference, which is why the choice is a statement about what you believe. The full comparison is on כש־ or אם?.

The counterfactual: what אם is and is not

Hebrew has dedicated openers for a condition the speaker knows to be false — אילו, לו, and the negative לולא — and אם is not one of them. But do not go on to say that אם cannot appear in a counterfactual, because in everyday speech it constantly does. What actually marks the sentence as counterfactual is the היה + participle frame in both halves, not the opener.

אם הייתי במקומך, לא הייתי מחכה לתשובה שלהם.

im hayíti bimkomkhá, lo hayíti mekhaké latshuvá shelahém

If I were you I wouldn't wait for their answer. (to a man — everyday speech; written up, this would open with אילו)

So: אם is the word for an open condition, and it is also what speech uses for a closed one. Write אילו, say אם — the reasoning is on unreal conditionals.

The compounds: אם כי, אם כן, אם כך

אם כי is not a conditional at all. It is the written concessive — although, albeit — and it is far commoner than learners expect: insource:/ אם כי / returns a five-figure floor on Hebrew Wikipedia — 17,166–17,585 across runs on 17 August 2026, a string too common to sit still — and every hit in a sampled handful is the concessive, in ordinary encyclopedic prose. Meeting it and parsing it as "if that" will derail an entire sentence.

הפגישה הייתה קצרה, אם כי יעילה מאוד.

hapgishá haytá ktsará, im ki ye'ilá me'ód

The meeting was short, though very productive. (formal written)

אם כך and אם כן both mean in that case, so then, drawing a conclusion from what was just said. אם כך is the ordinary spoken one; the same probe returns 247–274 for it.

אם כך, נדחה את הכול לשבוע הבא.

im kakh, nidkhé et hakól lashavúa habá

In that case, let's push everything back to next week.

One more thing worth recognising and not copying: contracts and public-administration prose open conditions with היה ו־ and במידה ו־ (היה והופסקה העסקתו…). The Academy holds both non-standard and names אם as the word properly suited to opening a conditional clause; the detail is on real conditionals.

Both jobs in one exchange

תגיד, אם תסיים מוקדם, בא לך לקפוץ אלינו?

tagíd, im tesayém mukdám, ba lekhá likpóts eléinu?

Listen, if you finish early, do you fancy dropping by? (to a man — condition)

אני לא יודע אם אספיק, יש לי משמרת עד שבע.

aní lo yodéa im aspík, yesh li mishméret ad shéva

I don't know whether I'll make it — I've got a shift until seven. (m. speaker — the same word, now 'whether')

אז אם לא תספיק, נדחה את זה למחר.

az im lo taspík, nidkhé et ze lemakhár

Then if you can't make it we'll put it off till tomorrow. (to a man — condition again, with the spoken אז)

Common Mistakes

1. A present tense in the אם clause for one specific future event. The English will-ban carried straight over. What comes out is grammatical Hebrew that describes a standing arrangement instead of tomorrow.

❌ אם היא מתקשרת, תגידי לה שיצאתי

if she calls, tell her I've gone out

Incorrect as an instruction about today — the present makes it a standing rule, 'whenever she calls, tell her'. For one expected call the verb goes into the future: אם היא תתקשר, תגידי לה שיצאתי.

✅ אם היא תתקשר, תגידי לה שיצאתי לחצי שעה.

im hi titkashér, tagídi la sheyatsáti lakhatsí sha'á

If she calls, tell her I've popped out for half an hour. (to a woman)

2. Writing עם for אם. The two are homophones in Israeli Hebrew — both im — so the ear gives you nothing and only the spelling separates if from with.

❌ עם יש לך זמן, תעבור על המסמך

Incorrect as a spelling — עם is 'with' and אם is 'if', and they sound identical. אם יש לך זמן, תעבור על המסמך.

✅ אם יש לך זמן, תעבור על המסמך לפני שאשלח אותו.

im yesh lekhá zman, ta'avór al hamismákh lifnéi she'eshlákh otó

If you've got time, go over the document before I send it. (to a man)

3. Using bare אם for although. The concessive needs both words. Drop the כי and you have flipped a concession into a condition.

❌ אם הוא צודק, אני עדיין לא מסכים איתו

although he's right, I still don't agree with him

Incorrect as that sentence — bare אם is 'if', so this reads 'if he's right, I still don't agree'. The concessive is the two-word אם כי, or in speech למרות ש־.

✅ אם כי הוא צודק בעיקרון, בפועל זה לא עובד ככה.

im ki hu tsodék ba'ikarón, befó'al ze lo ovéd kákha

Although he is right in principle, in practice it doesn't work that way. (formal written)

4. Splitting whether or not. English lets the or not jump forward to sit beside the whether. Hebrew keeps the clause whole and puts או לא at the end.

❌ אני לא יודעת אם או לא הוא מגיע

Incorrect — the alternative cannot be moved in front of the clause. Put the clause first and או לא at the end: אני לא יודעת אם הוא מגיע או לא.

✅ אני לא יודעת אם הוא מגיע או לא, הוא לא ענה לי כל היום.

aní lo yodá'at im hu magía o lo, hu lo aná li kol hayóm

I don't know whether he's coming or not — he hasn't answered me all day. (f. speaker)

Key Takeaways

אם does two unrelated jobs: it opens a real condition (אם תבוא בשמונה נספיק לאכול) and it embeds a yes-no question (תבדקי אם הסניף פתוח). English merges them too, which is why the join is invisible.
The test: if או לא can be added at the end, the sense is whether; if אז can open the main clause, it is a condition.
A condition about the future takes a future verb in both halves — an English rule to switch off.
האם opens a direct question; אם embeds one. The Academy rules that an indirect question takes אם, while noting that embedded האם is ordinary in journalistic prose. Nobody says האם out loud.
אם leaves the event open where כש־ leaves only the timing open.
The dedicated counterfactual openers are אילו and לו, but everyday speech opens counterfactuals with אם as well. What marks a sentence counterfactual is היה + participle, not the opener.
אם כי is although, not a conditional, and it is common in written Hebrew. אם כך / אם כן mean in that case.
בין אם … ובין אם covers both branches at once instead of asking about them: בין אם תבוא ובין אם לא.
