English makes something, anything, nothing and everything look like one tidy four-member family. Hebrew does not. משהו is the ordinary positive indefinite, הכול is the total set, כל דבר expresses free choice, and כלום / שום דבר are polarity expressions that normally live inside a negative structure. The crucial fact is that neither of the last two contains negation by itself.
The map
| Hebrew | Reading | Core meaning | Register / syntax |
|---|---|---|---|
| משהו | máshehu | something; anything in a positive question | neutral, masculine singular agreement |
| כלום | klum | anything under negation; “nothing” in translation | everyday/informal, normally requires a licensor |
| שום דבר | shum davár | any thing at all under negation | neutral, normally requires a licensor |
| הכול | hakól | everything | masculine singular for non-human reference |
| כל דבר | kol davár | anything, any thing whatsoever | free choice, not negative polarity |
| דבר מה | davár ma | something, a certain thing | (formal/written) |
משהו מוזר קרה במערכת אחרי העדכון.
máshehu muzár kará bama'arékhet akharéi ha'idkún
Something strange happened in the system after the update.
אתה צריך משהו מהסופר לפני שאני חוזר?
atá tsaríkh máshehu mehasúper lifnéi she'aní khozér?
Do you need anything from the supermarket before I come back? (to a man, m. speaker)
Like human מישהו, positive משהו covers English something and interrogative anything. It is a pronoun, not a determiner: an adjective can follow it (משהו מוזר), but a noun cannot be placed after it as though it meant English some.
כלום and שום דבר do not mean “not”
The Academy of the Hebrew Language's explanation כלום ושום דבר is explicit: neither expression carries negation. Historically כלום means “something, anything, the least amount,” while שום דבר is “any thing whatsoever.” Thus לא אכלתי כלום is built like English I didn't eat anything, not like I ate nothing.
לא ראיתי כלום דרך החלון בגלל הערפל.
lo ra'íti klum dérekh hakhalón biglál ha'arafél
I couldn't see anything through the window because of the fog.
שום דבר לא קרה בזמן שהיינו בחוץ.
shum davár lo kará bizmán shehayínu bakhúts
Nothing happened while we were out.
לא נשאר כלום במקרר חוץ מחצי לימון.
lo nish'ár klum bamekarér khuts mekhatsí limón
There's nothing left in the fridge except half a lemon.
אין לי שום דבר להוסיף למה שכבר נאמר.
ein li shum davár lehosíf lemá shekhvár ne'emár
I have nothing to add to what has already been said.
The licensor need not be לא. אין supplies negation in an existential clause; אל does so in a prohibition; בלי does so in a prepositional phrase. Once one of those is present, no extra לא is added: אין לי כלום, אל תגיד שום דבר, בלי כלום.
The exception: short answers and a fixed contrast
When the clause disappears, there is no verb for a negator to accompany. Both expressions can therefore stand alone as short dialogue answers.
מה אכלת בצהריים? — שום דבר, לא היה לי זמן.
ma akhálta batsohoráyim? shum davár, lo hayá li zmán
What did you eat for lunch? — Nothing; I didn't have time. (to a man)
מה עשיתם שם כל הערב? — כלום, רק חיכינו.
ma asítem sham kol ha'érev? klum, rak khikínu
What did you do there all evening? — Nothing; we just waited. (to a group)
The fixed expression הכול או כלום “all or nothing” likewise contains no separate negator. It names two alternatives rather than forming a negative clause.
מבחינתו זה הכול או כלום, ואין מקום לפשרה.
mibkhinató ze hakól o klum, ve'éin makóm lifshará
As far as he's concerned, it's all or nothing, with no room for compromise.
These are narrow exceptions: a fragment or a memorized coordination. They do not make a positive declarative such as כלום קרה mean “nothing happened.” As a question opener, כלום קרה? belongs to the separate older interrogative use described below.
הכול: one “everything,” singular agreement
For non-human reference, הכול is grammatically masculine singular. English all can feel plural, but Hebrew asks whether the word denotes the totality of things or a group of people.
הכול מוכן לסעודה.
hakól mukhán lase'udá
Everything needed for the meal is ready. (non-human reference; masculine singular)
הכול מוכנים לסעודה.
hakól mukhaním lase'udá
Everybody is ready for the meal. (classical/elevated human use; plural agreement)
This Academy minimal pair shows that agreement identifies the reading. The second sentence uses the older human “everybody” sense treated on human indefinites; the ordinary modern human pronoun is כולם.
הכול נראה מסובך בהתחלה, אבל נסתדר.
hakól nir'é mesubákh bahatkhalá, avál nistadér
Everything looks complicated at first, but we'll manage.
כל דבר and דבר מה
For free choice — “any thing, it does not matter which” — use כל דבר. It is positive and does not require a negator.
אפשר לשאול אותי כל דבר, גם שאלה לא נעימה.
efshár lish'ól otí kol davár, gam she'elá lo ne'imá
You can ask me anything, even an uncomfortable question.
קח כל דבר שאתה צריך מהשולחן.
kakh kol davár she'atá tsaríkh mehashulkhán
Take anything you need from the table. (to a man)
דבר מה is a formal written counterpart of משהו. It typically introduces an unspecified but noteworthy fact or event.
אירע דבר מה בלתי צפוי במהלך הבדיקה.
erá davár ma biltí tsafúy bemahalákh habdiká
Something unexpected occurred during the inspection. (formal/written)
Do not use שום דבר for free-choice anything in a positive clause. Modern שום דבר and כלום are used essentially in negative structures, apart from the fragments and fixed expression above.
The spelling of כל and כול
The Academy's standard is systematic. When the word stands alone, it is pointed כֹּל and takes a vav in unpointed ktiv male: הכול, קודם כול, כול יכול, מכול וכול. When it is bound to a following word, it is pointed כָּל (pronounced kol in Israeli Hebrew) and written without vav: כל דבר, כל היום, כל מה.
| Position | Standard spelling | Example |
|---|---|---|
| standalone | כול | הכול · קודם כול · מכול וכול |
| bound to what follows | כל | כל דבר · כל היום · כל מה שצריך |
Learners will frequently encounter הכל in older texts and in modern writing that follows an older unpointed convention. Recognize it as the same word, not as a different pronoun. For your own standard spelling, write הכול; the broader usage picture is documented on כל: all and every.
An older interrogative כלום
Pointed כְּלוּם also survives in an unrelated (archaic/formal) use as a rhetorical-question particle expecting a negative answer — roughly “is it conceivable that…?”
כלום יעלה על הדעת שנבטל את החוק בגלל טעות אחת?
klum ya'alé al hadá'at shenevatél et hakhók biglál ta'út akhát?
Could it conceivably be suggested that we repeal the law because of one mistake? (archaic/formal rhetorical question; expected answer: no)
Wiktionary labels this interrogative use archaic and labels separate senses “nothing at all” and “a negligible amount” as slang. That is useful register information; Milog's lack of a label is not counter-evidence, because Milog does not systematically apply register labels. In ordinary negative concord, however, לא … כלום is an everyday informal construction, not an antiquarian curiosity.
Common Mistakes
1. Expecting כלום to negate a positive verb. The negator is missing.
❌ ראיתי כלום בחדר
Incorrect — כלום is licensed by a negative clause: לא ראיתי כלום בחדר.
✅ לא ראיתי כלום בחדר חוץ מכיסא שבור.
lo ra'íti klum bakhéder khuts mikisé shavúr
I saw nothing in the room except a broken chair.
2. Using כלום as a determiner before a noun. כלום stands by itself; שום is the determiner.
❌ לא קיבלנו כלום תשובה מהבנק
Incorrect — כלום cannot modify תשובה. Use the determiner שום: לא קיבלנו שום תשובה מהבנק.
✅ לא קיבלנו שום תשובה מהבנק עד הערב.
lo kibálnu shum tshuvá mehabánk ad ha'érev
We received no answer from the bank until the evening.
3. Giving non-human הכול plural agreement. The plural string has a legitimate human reading, so the error is the intended meaning, not the Hebrew words themselves.
❌ הכול מוכנים
Everything is ready.
Incorrect as the non-human reading — מוכנים makes הכול human and plural: ‘everybody is ready.’ For things, write הכול מוכן.
✅ הכול מוכן למשלוח, רק חסרה חתימה.
hakól mukhán lemishlóakh, rak khaserá khatimá
Everything is ready for dispatch; only a signature is missing.
4. Marking משהו with את as though it were definite. The pronoun is indefinite.
❌ קניתי את משהו לאכול בדרך
Incorrect — משהו is indefinite, so a direct object does not take את: קניתי משהו לאכול בדרך.
✅ קניתי משהו קטן לאכול בדרך לעבודה.
kaníti máshehu katán le'ekhól badérekh la'avodá
I bought something small to eat on the way to work.
5. Using שום דבר for positive free choice. “Any one whatsoever” is כל דבר.
❌ אתה יכול לבחור שום דבר מהתפריט
Incorrect — שום דבר belongs under negation. For free choice say אתה יכול לבחור כל דבר מהתפריט.
✅ אתה יכול לבחור כל דבר מהתפריט, הכול כלול במחיר.
atá yakhól livkhór kol davár mehatafrít, hakól kalúl bamekhír
You can choose anything from the menu; everything is included in the price. (to a man)
Key Takeaways
- משהו is positive “something” and also covers interrogative English “anything.” It is a pronoun, not a determiner.
- Neither כלום nor שום דבר contains negation. Use לא ראיתי כלום, שום דבר לא קרה, אין לי שום דבר.
- In their modern negative-polarity use, they can stand without a negator only as clause-less answers and in fixed הכול או כלום; older interrogative כלום is a separate construction.
- Non-human הכול takes masculine singular agreement: הכול מוכן. Elevated human הכול takes plural agreement: הכול מוכנים.
- Positive free-choice “anything” is כל דבר; דבר מה is formal/written “something.”
- Standard standalone spelling has vav (הכול, קודם כול); bound כל has none (כל דבר). Recognize the older unpointed spelling הכל, but write the standard הכול.
- Interrogative כלום in a rhetorical question is archaic/formal and separate from everyday negative-concord כלום.

- Negative Concord: אף אחד לא, שום דבר לאA2 — אף אחד לא בא is not a double negative — the Academy's position is that neither כלום nor שום דבר carries any negation of its own, so nothing is being doubled. Hebrew marks one negation on more than one word, which is why the לא is compulsory and dropping it leaves a string with no reading at all.
- מישהו, מישהי, כולם, אף אחדA2 — Hebrew distinguishes positive human indefinites such as מישהו from polarity forms such as אף אחד, which require a separate negator, while כולם and כל אחד trigger different agreement.
- Spellings Israelis Themselves Argue AboutC2 — תוכנית or תכנית, דוגמה or דוגמא, אימא or אמא — a set of words where the Academy prescribes one form and educated Israelis write the other. Knowing which spellings are genuinely contested is what stops three native speakers from correcting you three different ways.
- Saying 'Some' and 'Any' in HebrewB2 — Hebrew has no word for 'some' and no word for 'any', so this is a translation problem rather than a grammar rule. Most of the time the answer is nothing at all — יש חלב במקרר is 'there's some milk in the fridge' — and the rest of the time it depends on which of English's three quite different 'any's you are actually trying to say.
- כל: All, Every, WholeA2 — One word, two meanings, and the article on the NEXT word decides which: כל יום is 'every day', כל היום is 'all day'. כל itself never changes. Then there is the free-standing form הכול, which is spelled differently for a reason that goes back to the maqaf.
