1. The Central Axiom
Universal principle of Siman י׳:
Everything depends on the shape of the garment. The obligation of tsitsit holds only for a garment of four corners (ד׳ כנפות): fewer than four → patour; more than four → ḥayav, and one places the tsitsit on the four most distant corners (המרוחקות זו מזו יותר). The corners must be square (מרובעות), not rounded. For garments open at the sides, all depends on the רוב: רוב סתום → patour, רוב פתוח → ḥayav, and חציו-חציו לחומרא. The תעשה ולא מן העשוי requires the tsitsit be made after the obligation. And a garment whose primary use is to cover the head or shoulder (מצנפת, scarf) is patour — כסותך ולא כסות הראש.

💡 The universal key: the mitzva turns on the geometry — four square corners, sufficiently closed, and a body garment. Any deviation from this shape exempts or invalidates.
- ד׳ כנפות → fewer than 4 patour; more than 4 ḥayav (the 4 most distant)
- תעשה ולא מן העשוי → tsitsit made before the obligation is pasoul
- רוב פתוח / רוב סתום → open ḥayav, closed patour, חציו-חציו לחומרא
- מרובעות + כסותך → square corners; headcovering and scarf exempt
2. Master table of the 12 seifim
The 12 seifim of the Mechaber group naturally into six families: (A) the ד׳ כנפות (the number of corners), (B) the material of the corners (cloth/leather), (C) the תעשה ולא מן העשוי, (D) the רוב פתוח/סתום, (E) the כנפות מרובעות, (F) the כסות הראש/הכתף exempt.
| Family | Seif | Heart of the halakha | Marker |
|---|---|---|---|
| A. ד׳ כנפות |
① | A talit of fewer than 4 corners is patour; of more than 4 → ḥayav, and one places 4 tsitsit on the 4 most distant corners from one another. | ד׳ כנפות |
| ② | 4 corners, and he cut one diagonally (באלכסון) in two → it has become a garment of 5 corners and ḥayav. | בעלת ה׳ | |
| ③ | He folded the corners of his talit and knotted or sewed them, as if he had cut them (קיצען) → even so, it is not exempted. | לא נפטרה | |
| B. חומר הכנף |
④ | A talit of cloth with leather corners → ḥayav; a talit of leather with cloth corners → patour (one follows the body of the garment). | בגד וכנפיה של עור |
| C. תעשה ולא מן העשוי |
⑤ | It had 3 corners + 3 tsitsit, then he added a 4th corner and its tsitsit → pasoul משום תעשה ולא מן העשוי (the tsitsit made before the obligation). | תעשה ולא מן העשוי |
| ⑥ | One does not fold the talit to place the tsitsit on the folded corners (unless sewn); הטיל ציצית על ציצית: to annul the first → cut it and it is kosher; to add → pasoul. Rama: וי״א who validate in any case, וכן עיקר (Rif, Rosh, Rabbeinu Yerucham). | ציצית על ציצית | |
| D. רוב פתוח סתום |
⑦ | Garments open at the sides below, with 4 corners, but closed above: רוב סתום → patour; רוב פתוח → ḥayav; חציו-חציו → לחומרא ḥayav, ואין יוצאין בו בשבת. | רובו פתוח / רובו סתום |
| ⑧ | The קאפ"ה that is open (with 4 corners): closing it with an אשטרינג"ה to exempt it avails only if fixed at least from the middle downward and below the belt, so the רוב סתום is visible to the eyes — otherwise it is forbidden משום מראית העין. | מראית העין | |
| E. כנפות מרובעות |
⑨ | The corners must be square (מרובעות) and not rounded (עגולות). | מרובעות ולא עגולות |
| F. כסות הראש והכתף |
⑩ | The מצנפת is patour, even one whose two ends fall over the shoulders and the body — for its primary use is to cover the head: כסותך אמר רחמנא ולא כסות הראש. | מצנפת פטורה |
| ⑪ | The shoulder scarf (סודר / שי"ד / ביק"א) worn on the neck or shoulders is patour. | סודר פטור | |
| ⑫ | Certain garments (גוח"ש, מינטי"ני…) are patour even with 4 corners. Rama: likewise garments whose corners are not 2 in front and 2 behind, aligned (Beit Yossef per Mahari"k). | אע"פ שיש להם ד׳ כנפים |
⚖ The structure of the siman at a glance
The 12 seifim of the Mechaber decide when a garment is ḥayav in tsitsit according to its shape: (A) ד׳ כנפות — fewer than 4 patour, more than 4 ḥayav (the 4 most distant); (B) the material of the corners; (C) the תעשה ולא מן העשוי and the ציצית על ציצית; (D) the רוב פתוח/סתום and the מראית העין; (E) the כנפות מרובעות; (F) the כסותך ולא כסות הראש — the מצנפת and scarf exempt. The Shulchan Aruch HaRav (the Alter Rebbe) unfolds this siman into 23 seifim: the precise definition of the כנפות, the law of רוב פתוח/סתום, the yesod of תעשה ולא מן העשוי and the status of the מצנפת.3. The ד׳ כנפות — the number of corners
Q: How many corners make a garment obligated in tsitsit?
↓
🔴 Fewer than 4 corners — פטורה: the garment is not obligated (seif 1).
🟢 More than 4 corners — חייבת: one places the tsitsit on the 4 most distant corners from one another (seif 1).
🟢 4 → 5 by diagonal — Cut a corner באלכסון in two → it becomes a garment of 5 corners and ḥayav (seif 2).
🟢 Folded/sewn corners — Knotted or sewed them as if cut → it is not exempted (seif 3).
The geometry of the mitzva
The siman opens on the geometric yesod: the mitzva holds for a garment of four corners, neither fewer nor more as a structure. With more than four, the Torah requires only four tsitsit, placed on the four most distant corners; with a corner cut in two, one crosses the threshold of four and becomes ḥayav; and one cannot undo the obligation by knotting or sewing the corners (seif 3). For the status of leather at the corners (seif 4: one follows the body of the garment) and the details of the nossei kelim (Beit Yossef, Tour, Menachot 41a-43b), see Level 2; the yesod and the psak, in Level 4.
4. תעשה ולא מן העשוי — the mitzva made after the obligation
Q: Is a tsitsit made before the garment was obligated valid?
↓
🔴 3 corners + 3 tsitsit, then a 4th — Added a 4th corner and its tsitsit afterward → pasoul משום תעשה ולא מן העשוי (seif 5).
🟡 Folding the talit — One does not place the tsitsit on the folded corners (unless sewn); they must go on the 4 spread-out corners (seif 6).
🟢 ציצית על ציצית — To annul the first → cut it, kosher; to add → pasoul. Rama: וי״א who validate in any case, וכן עיקר (seif 6).
📚 The yesod of seif 5: the mitzva must be תעשה — performed — and not מן העשוי — arising from an act already done. When the 3 tsitsit were attached, the garment was not yet obligated (3 corners); by adding the 4th corner the obligation is born, but the 3 existing tsitsit were made before it. This is the same yesod as the ציצית על ציצית: all depends on the intention (annul/add). The detail is treated in Level 4.
5. רוב פתוח / רוב סתום — open-sided garments
Q: Is a garment open at the sides obligated in tsitsit?
↓
🔴 רוב סתום — The majority closed → patour (seif 7).
🟢 רוב פתוח — The majority open → ḥayav (seif 7).
🟡 חציו-חציו — Half and half → לחומרא ḥayav, but ואין יוצאין בו בשבת (seif 7).
⚠️ קאפ"ה / אשטרינג"ה — Closing it to exempt it avails only if the רוב סתום is visible; otherwise forbidden משום מראית העין (seif 8).
The law of רוב
A 4-cornered garment open at the sides is a safek of shape: is it a garment of four corners, or a slit garment? The Mechaber decides by the רוב — the majority closed likens it to a non-obligated garment, the majority open to a 4-cornered one. At חציו-חציו, one is ḥayav לחומרא, and one does not go out with it on Shabbat (lest one wear a non-obligated garment, or invalid tsitsit). And artificially closing a garment does not suffice if the מראית העין gives the opposite impression (seif 8). The yesod of this law is developed in Level 4 (refer to the Rav).
6. כנפות מרובעות — the square corners
Q: What shape must the corners of the talit have?
↓
🟢 מרובעות — square — The corners must be square (seif 9).
🔴 עגולות — rounded — Rounded corners do not suffice (seif 9).
📚 The yesod of seif 9: the « corner » (כנף) that the Torah designates is a square point — an angle. A rounded corner is no longer a כנף in the halakhic sense, and the tsitsit placed there would miss its place. This is why, in practice, one ensures the four corners of the talit are well squared before placing the threads.
7. כסות הראש / הכתף — מצנפת and scarf exempt
Q: Is a 4-cornered garment worn on the head or shoulder obligated?
↓
🔴 מצנפת — The headcovering is patour, even if its ends fall over the shoulders: its primary use is to cover the head (seif 10).
🔴 סודר / scarf — The shoulder scarf (שי"ד, ביק"א) is patour (seif 11).
🔴 Particular garments — Certain garments (גוח"ש…) are patour even with 4 corners; Rama: likewise if the corners are not aligned 2-2 (seif 12).
The yesod of כסותך
The Torah says כסותך — your garment (of the body) — ולא כסות הראש: not the headcovering. A garment whose primary use (עיקרה) is to cover the head or the shoulder is patour, even if it incidentally covers part of the body. Hence the מצנפת, the סודר and the scarf are exempt. The Rama adds a criterion of shape: if the four corners are not 2 in front and 2 behind, aligned, the garment is patour. The precise yesod is treated in Level 4 (refer to the Rav).
8. Golden rules — Memory Aid
The 6 golden rules of Siman י׳
- ד׳ כנפות — fewer than 4 patour; more than 4 ḥayav, the ד׳ המרוחקות.
- material — cloth with leather corners ḥayav; leather with cloth corners patour.
- תעשה ולא מן העשוי — tsitsit made before the obligation (3→4 corners) → pasoul.
- רוב — closed patour, open ḥayav, חציו-חציו לחומרא (not on Shabbat).
- מרובעות — square corners, never rounded (עגולות).
- כסותך — מצנפת and scarf exempt (ולא כסות הראש).
9. Mnemonic — Memory Aid
Acrostic: Q-M-T-R-S-K — the six families of Siman י׳
- Quatre corners — fewer than 4 patour; more than 4 ḥayav (the 4 most distant).
- Material — cloth with leather corners ḥayav; leather with cloth corners patour.
- Taasse — תעשה ולא מן העשוי: tsitsit made before the obligation → pasoul.
- Rov — closed patour, open ḥayav, חציו-חציו לחומרא.

3 foundational formulas to memorize:
- ד׳ כנפות המרוחקות זו מזו — the 4 most distant corners
- תעשה ולא מן העשוי — the mitzva made after the obligation
- כסותך ולא כסות הראש — the headcovering is exempt
10. Pitfalls to Avoid
❌ Pitfall 1: Believing that a garment of 5 or 6 corners requires 5 or 6 tsitsit.
→ The seif: one places only 4 tsitsit, on the 4 most distant corners from one another (seif 1).
→ The seif: one places only 4 tsitsit, on the 4 most distant corners from one another (seif 1).
❌ Pitfall 2: Thinking one can « undo » the obligation by knotting or sewing the corners.
→ The seif: even knotted or sewn like קיצען, the talit is not exempted (seif 3).
→ The seif: even knotted or sewn like קיצען, the talit is not exempted (seif 3).
❌ Pitfall 3: Attaching the tsitsit first, and only then forming the 4th corner.
→ The seif: 3 corners + 3 tsitsit then a 4th corner → pasoul משום תעשה ולא מן העשוי (seif 5).
→ The seif: 3 corners + 3 tsitsit then a 4th corner → pasoul משום תעשה ולא מן העשוי (seif 5).
❌ Pitfall 4: Going out on Shabbat with an open garment חציו-חציו « since it is ḥayav ».
→ The seif: at חציו-חציו, ḥayav לחומרא but ואין יוצאין בו בשבת (seif 7).
→ The seif: at חציו-חציו, ḥayav לחומרא but ואין יוצאין בו בשבת (seif 7).
❌ Pitfall 5: Placing tsitsit on a 4-cornered headcovering or scarf.
→ The seif: the מצנפת and the scarf are exempt — כסותך ולא כסות הראש (seifim 10-11).
→ The seif: the מצנפת and the scarf are exempt — כסותך ולא כסות הראש (seifim 10-11).
11. The talit in practice
| Step | Conduct | Base halakha |
|---|---|---|
| ① The number of corners | A talit of 4 corners; more than 4 → the 4 most distant | ד׳ כנפות |
| ② The shape of the corners | Square corners, never rounded | מרובעות |
| ③ The order of acts | First form the obligated garment, then place the tsitsit | תעשה ולא מן העשוי |
| ④ Open garment | Measure the רוב; on Shabbat, do not go out with a חציו-חציו | רוב פתוח / רוב סתום |
| ⑤ Headcovering / scarf | No tsitsit: they are exempt (כסות הראש/הכתף) | כסותך ולא כסות הראש |
| ⑥ Fine cases | Open talit-katan, torn corner to remake, closure: refer to the Rav | SA HaRav — 23 seifim |
