In short

Some verbs don’t take a plain noun as their object — they take a whole clause. “I know that he’s right”, “she thinks the movie is boring”, “I want you to come”. In Hebrew that embedded clause is tied on with one small piece: ש־ (she-), written glued onto the next word, the same subordinating tie you already met in causal, purpose and temporal clauses. Here it turns a sentence into the object of a verb.

Two jobs live in this lesson, and one fork decides everything. After verbs of knowing, saying, thinking, feeling (יודע, אומר, חושב, מרגיש), ש־ introduces a factual clause that keeps its own tense. After verbs of wishing and requesting (רוצה, מבקש, מעדיף) the choice depends on the subject: same subject → an infinitive (אני רוצה לבוא, “I want to come”); a different subject → ש־ + a future verb (אני רוצה שתבוא, “I want you to come”). Getting that same-subject/different-subject fork right is the heart of the lesson.

The rule

• Factual object clause: verb + ש־ + a clause that keeps its own tense. After a verb of saying, thinking, knowing, hoping or perceiving, the thing known or said is a full clause hooked on with ש־: אני יודע שהוא צודק (ani yode’a she-hu tzodek, “I know that he’s right”); היא חושבת שהסרט משעמם (hi choshevet she-ha-seret mesha’amem, “she thinks the movie is boring”). The embedded verb carries the tense the fact has as seen from the moment of the main verb — present for something true at that moment, past for something before it, future for something still to come: הם מקווים שירד גשם (hem mekavim she-yered geshem, “they hope it’ll rain” — future, because the rain is still to come); הוא הרגיש שמשהו לא בסדר (hu hirgish she-mashehu lo beseder, “he felt that something was wrong” — present, because it was wrong at the moment he felt it). Hebrew does not shift that tense to match the main verb the way English turns “is” into “was” (reported speech, a later lesson, keeps the tense the same way).

• Never drop ש the way English drops “that”. English lets you say “I think he’s right” with no “that”. Hebrew cannot: the ש is obligatory. אני חושב הוא צודק is simply ungrammatical — it must be אני חושב שהוא צודק (ani choshev she-hu tzodek). If there’s an embedded clause, there’s a ש in front of it, every time.

• ש־ glues on with no space. Like ב־, ל־, ה־ and כש־, the complementizer ש־ attaches directly to the following word: שהוא, שאני, שירד — never ש הוא. A space here is a spelling mistake.

• The wish/request fork — same subject vs different subject. Verbs like רוצה (rotze, “want”), מבקש (mevakesh, “ask/request”), מעדיף (ma’adif, “prefer”) point at a desired situation. If the wanter and the doer are the same person, use a bare infinitive (see Infinitive (shem ha-po’al) + modals): אני רוצה לבוא (ani rotze lavo, “I want to come” — I come). If the doer is someone else, you cannot use an infinitive — switch to ש־ + a verb in the future tense: אני רוצה שתבוא (ani rotze she-tavo, “I want you to come” — you come). This is the same “ש + future” you saw after כדי ש and עד ש: it’s Modern Hebrew’s stand-in for a subjunctive, the mood English marks with “to come / that he come”.

• After רוצה ש the verb is FUTURE, never present. Because the wished-for event hasn’t happened, its verb looks forward: אני רוצה שתבוא (she-tavo, future), not אני רוצה שאתה בא (present בא). The same holds for מבקש ש, מעדיף ש and the impersonal triggers below.

• מבקש takes the person with מ־ (“from”). “To ask someone to do something” is מבקש מ־ + person, then ש־ + future: ביקשתי ממנה שתעזור לי (bikashti mimena she-ta’azor li, “I asked her to help me”). The one you address is marked with the inflected מ־ (see Prepositions inflected for pronoun); the requested act goes into the ש-clause.

• Impersonal חשוב ש / כדאי ש + future. Impersonal “it’s important / it’s advisable that…” work the same way: חשוב שתלמד לפני המבחן (chashuv she-tilmad lifnei ha-mivchan, “it’s important that you study before the exam”), כדאי שתנוח קצת (keday she-tanuach ktzat, “you’d better rest a bit”). These have no personal subject of their own, so they always take ש־ + future — there’s no same-subject infinitive option.

Examples

Common mistakes

• אני רוצה לבוא אתה -> אני רוצה שתבוא (ani rotze she-tavo) - across a subject switch you can never use an infinitive; a different doer needs ש־ + future.
• אני רוצה שאני אבוא / אני רוצה שאבוא (meaning “I want to come”) -> אני רוצה לבוא (ani rotze lavo) - when the subject stays the same, use the bare infinitive, not ש־.
• אני חושב הוא צודק -> אני חושב שהוא צודק (ani choshev she-hu tzodek) - Hebrew can’t drop the complementizer the way English drops “that”; ש is obligatory.
• אני רוצה שאתה בא -> אני רוצה שתבוא (ani rotze she-tavo) - after רוצה ש the embedded verb is FUTURE, never the present.
• אני יודע ש הוא צודק -> אני יודע שהוא צודק (ani yode’a she-hu tzodek) - ש־ attaches with no space, like ב־ / ל־ / ה־.
• ביקשתי אותה שתעזור -> ביקשתי ממנה שתעזור (bikashti mimena she-ta’azor) - the person you ask is marked with מ־ (“from”), not with the object marker.
• חשוב שאתה לומד לפני המבחן -> חשוב שתלמד לפני המבחן (chashuv she-tilmad lifnei ha-mivchan) - impersonal חשוב ש / כדאי ש also take a future verb, not the present.

Tips

• One question settles the wish/request pattern: same subject or different? Same → infinitive (אני רוצה לבוא). Different → ש־ + future (אני רוצה שתבוא). Say it to yourself before you build the sentence.
• After a wanting/asking verb with a new subject, the embedded verb is always future — it’s Hebrew’s subjunctive-substitute. Present after רוצה ש is wrong.
• After a knowing/saying/feeling verb, do the opposite: keep the clause’s own real tense, seen from the moment of the main verb. What’s true at that moment stays present, what happened before it stays past, what’s still coming stays future.
• Never leave out ש. If there’s a clause riding as the object, it opens with ש — no exceptions, even where English hides “that”.
• ש־ is one glued letter. If your finger reached for the spacebar (ש הוא), it’s a spelling error — write שהוא.
• “Ask someone to…” = מבקש מ־ + person + ש־ + future: ביקשתי ממך שתחכה (bikashti mimcha she-techake, “I asked you to wait”).
• The impersonal triggers חשוב ש and כדאי ש have no subject of their own, so they skip straight to ש־ + future — there’s no infinitive alternative to weigh.
