The gutturals are not a גזרה in the ordinary sense. פ״נ and ל״ה are defined by a slot; א, ה, ח and ע cause trouble wherever they sit, so a root can be guttural and פ״נ and ל״ה at once. What holds them together is not a position but a pair of refusals, set out in full on gutturals: they will not carry a plain mobile shva, and they will not carry a dagesh.
Neither refusal changes a consonant. Both force a vowel to move — and which vowel moves depends entirely on where in the root the letter is standing. This page takes the three positions in turn and asks what each does across all seven binyanim. Niqqud throughout, because in ktiv male none of it is visible and almost all of it is audible.
First position: the prefix bends
ח־שׁ־ב is the ideal test root, because Pealim gives it a live verb in all seven binyanim — which almost no root has.
| בניין | past (he) | present m.sg. | infinitive | Meaning |
|---|---|---|---|---|
| pa'al | חָשַׁב khasháv | חוֹשֵׁב khoshév | לַחְשׁוֹב lakhshóv | thought |
| nif'al | נֶחְשַׁב nekhsháv | נֶחְשָׁב nekhsháv | לְהֵיחָשֵׁב lehekhashév | is considered (to be) |
| pi'el | חִישֵּׁב khishév | מְחַשֵּׁב mekhashév | לְחַשֵּׁב lekhashév | calculated |
| pu'al | חוּשַּׁב khusháv | מְחוּשָּׁב mekhusháv | — none exists | was calculated (formal) |
| hif'il | הֶחְשִׁיב hekhshív | מַחְשִׁיב makhshív | לְהַחְשִׁיב lehakhshív | held in esteem (formal) |
| huf'al | הוֹחְשַׁב hokhsháv | מוֹחְשָׁב mokhsháv | — none exists | was esteemed (formal) |
| hitpa'el | הִתְחַשֵּׁב hitkhashév | מִתְחַשֵּׁב mitkhashév | לְהִתְחַשֵּׁב lehitkhashév | took into account |
Those two huf'al cells need a word about their vav: the vowel on it is a kamatz katan, an o, not a shuruk — and ktiv male writes every o with a vav, so they are pointed exactly as they are spelled. Pealim gives the kubuts reading הֻחְשַׁב ~ הוחשב as an equally current second one, so you will hear hukhsháv too.
Now line the prefixes up against a sound root and the whole of first position is one column:
| Cell | Sound root | Guttural first radical | What moved |
|---|---|---|---|
| pa'al future | יִכְתּוֹב yikhtóv | יַחְשׁוֹב yakhshóv · יַעֲמוֹד ya'amód | chirik → patach |
| pa'al infinitive | לִכְתּוֹב likhtóv | לַחְשׁוֹב · לַעֲמוֹד | chirik → patach |
| nif'al past | נִסְגַּר nisgár | נֶחְשַׁב nekhsháv · נֶעֱמַד ne'emád | chirik → segol |
| nif'al future | יִיסָּגֵר yisagér | יֵיחָשֵׁב yekhashév · יֵיעָמֵד ye'améd | chirik → tsere (no dagesh available) |
| hif'il past | הִסְבִּיר hisbír | הֶחְשִׁיב hekhshív · הֶעֱמִיד he'emíd | chirik → segol |
| huf'al past | הוּסְבַּר husbár | הוֹחְשַׁב hokhsháv · הוֹעֳמַד ho'omád | shuruk → kamatz katan |
| pi'el past | דִּיבֵּר dibér | חִישֵּׁב khishév · עִימֵּד iméd | nothing |
| hitpa'el past | הִתְלַבֵּשׁ hitlabésh | הִתְחַשֵּׁב hitkhashév | nothing |
The last two rows are the ones that make the rest make sense. pi'el and hitpa'el hand the first radical a full vowel of its own — a chirik in חִישֵּׁב, a patach in הִתְחַשֵּׁב — so there is no shva to refuse and nothing bends. Every other binyan asks that radical to sit on a reduced vowel, and the prefix in front of it pays for the refusal.
הוא נחשב לאחד המומחים הגדולים בתחום, וזה לא סתם.
hu nekhsháv le'ekhád hamumkhím hagdolím batkhúm, vezé lo stam
He's considered one of the top experts in the field, and that's not for nothing.

hekhlátnu lo leha'amíd otó bamatsáv hazé
We decided not to put him in that position.
Middle position: only the binyanim that double are affected
This is where most treatments overstate the case. A middle guttural is a problem only for a binyan that wants to double the middle radical — and only three do.
- pi'el, pu'al and hitpa'el double it, so they must compensate. א and ר stretch the vowel in front (בֵּירֵךְ berékh, תֵּיאֵר te'ér, לְהִתְקָרֵא lehitkaré); ה, ח and ע take virtual doubling and keep the short vowel (מִיהֵר mihér, נִיהֵל nihél, שִׂיחֵק sikhék, הִתְנַהֵג hitnahég). That split is argued in full on dagesh and gutturals in pi'el.
- nif'al, hif'il and huf'al never double the middle radical, so their base forms are unaffected: נִשְׁאַל, הִשְׁאִיל, הוּשְׁאַל and נִבְחַר are shaped exactly like נִסְגַּר, הִסְבִּיר, הוּסְבַּר and נִכְתַּב — except that the shva under the guttural still becomes a chataf when an ending follows: נִשְׁאֲלָה against נִסְגְּרָה.
- pa'al is affected for a different reason: it puts a mobile shva on that radical in four cells, and it takes a patach in the future. שׁוֹאֲלִים, בּוֹחֲרִים, יִשְׁאַל, יִבְחַר — pa'al with a middle guttural owns this.
And the limit that keeps the whole picture honest: ר joins for the dagesh and for nothing else. It takes an ordinary mobile shva, and it does not pull the pa'al future to an a — יִדְרוֹשׁ, יִזְרוֹק and יִשְׂרוֹף keep their cholam while יִבְחַר and יִשְׁאַל do not.
הוא התנהג כאילו כלום לא קרה.
hu hitnahég ke'ílu klum lo kará
He behaved as if nothing had happened.
השאלתי לה את הרכב ליומיים וקיבלתי אותו נקי.
hish'álti la et harékhev leyomáyim vekibálti otó nakí
I lent her the car for two days and got it back clean.
הוא ידרוש התנצלות בכתב, אתה מכיר אותו.
hu yidrósh hitnatslút bikhtáv, atá makír otó
He'll want a written apology — you know what he's like. (to a man)
Third position: the vowel you can hear
ח and ע at the end of a word take a furtive patach — a short a written under the guttural and pronounced in front of it. Unlike the other two positions, this one survives into every binyan and is unmissable in speech.
| בניין | Infinitive | present m.sg. | present f.sg. |
|---|---|---|---|
| pa'al | לִפְתּוֹחַ liftóakh | פּוֹתֵחַ potéakh | פּוֹתַחַת potákhat |
| nif'al | לְהִיפָּתֵחַ lehipatéakh | נִפְתָּח niftákh | נִפְתַּחַת niftákhat |
| pi'el | לְפַתֵּחַ lefatéakh | מְפַתֵּחַ mefatéakh | מְפַתַּחַת mefatákhat |
| pu'al | — none exists | מְפוּתָּח mefutákh | מְפוּתַּחַת mefutákhat |
| hitpa'el | לְהִתְפַּתֵּחַ lehitpatéakh | מִתְפַּתֵּחַ mitpatéakh | מִתְפַּתַּחַת mitpatákhat |
| huf'al (שׁ־מ־ע) | — none exists | מוּשְׁמָע mushmá | מוּשְׁמַעַת mushmá'at |
| hif'il (שׁ־מ־ע) | לְהַשְׁמִיעַ lehashmía | מַשְׁמִיעַ mashmía | מַשְׁמִיעָהmashmi'á |
Two things to read out of that grid. The feminine singular is ־ַחַת / ־ַעַת in six binyanim — both vowels of the ending pulled to a — and only hif'il escapes, because its long i already fills the syllable and the ending reverts to a plain ־ָה. And the furtive patach is conditional: it appears only when the vowel in front of the guttural is not already an a. That is why every infinitive above has one (cholam or tsere in front) and why נִפְתָּח, מְפוּתָּח and מוּשְׁמָע do not — their kamatz has already supplied the a.

A last word on ה
A ה at the end of a verb is almost never a guttural: in קנה, רצה and בנה it is a vowel letter marking the final a, and those verbs are ל״ה, where nothing on this page applies. A final א is a real consonant but takes no furtive patach — that is ל״א.
Common Mistakes
1. Swallowing the furtive patach. The most audible error in the whole guttural system, and it survives for years because nothing in the spelling warns you.
❌ מתפתח, לפתוח, פותחת
mitpatékh · liftókh · potékhet
Incorrect — a final ח or ע after a non-a vowel takes a furtive patach, sounded before the letter: mitpatéakh, liftóakh. And the feminine pulls both ending vowels to a: potákhat, mefatákhat, niftákhat.
2. Giving a guttural-initial hif'il the ordinary הִ־. הִסְבִּיר is learned first and the prefix gets copied.
❌ החליט, העמיד
hikhlít · hi'amíd
Incorrect — a guttural first radical lowers the hif'il prefix to a segol: hekhlít, he'emíd. Compare הִדְלִיק hidlík and הִסְבִּיר hisbír, where the first radical is ordinary.
3. Carrying the la- prefix to a guttural that is not first. This is the positional error the page exists to kill: לַעֲמוֹד and לַחְשׁוֹב are learned early, and the prefix then travels to roots whose guttural sits somewhere else.
❌ לשמוע, לבחור
lashmóa · lavkhór
Incorrect — the la- prefix belongs to a guttural in FIRST position only. In שׁ־מ־ע and ב־ח־ר the guttural is at the end and in the middle, so the ordinary li- stands: lishmóa, livkhór — and likewise lish'ól, liftóakh, lid'óg.
✅ בוא נשמע קודם מה יש להם להציע.
bo nishmá kódem ma yesh lahém lehatsía
Let's hear what they have to offer first. (to a man)
4. Spreading the pa'al patach future to a middle ר. The five-letter list "א ה ח ע ר" is what does the damage.
❌ הוא יזרק את זה לפח
Incorrect as the pa'al future of זרק — ר forces no a-vowel, so the cholam stays and ktiv male needs the vav: הוא יזרוק את זה לפח, yizrók. (Pointed יִזָּרֵק is the nif'al, ‘will be thrown away’ — a different verb.)
✅ הוא יזרוק את זה לפח ואף אחד לא ישים לב.
hu yizrók et ze lapákh ve'áf ekhád lo yasím lev
He'll throw it in the bin and nobody will notice.
Key Takeaways
- The gutturals are positional in their effects, not in their membership: א, ה, ח and ע make trouble wherever they stand, and a root can be guttural and weak at the same time.
- First position bends the prefix, in every binyan that leaves the radical on a reduced vowel: יַחְשׁוֹב, לַחְשׁוֹב, נֶחְשַׁב, יֵיחָשֵׁב, הֶחְשִׁיב, הוֹחְשַׁב. pi'el and hitpa'el are untouched (חִישֵּׁב, הִתְחַשֵּׁב), because they give the radical a full vowel.
- Middle position matters only where a binyan doubles the middle radical — pi'el, pu'al, hitpa'el. nif'al, hif'il and huf'al are unaffected in their base forms: נִשְׁאַל, הִשְׁאִיל, הוּשְׁאַל are ordinary, and only a suffixed cell shows the chataf (נִשְׁאֲלָה). pa'al is affected for its own reasons (chataf plurals, patach future).
- In the doubling binyanim, א and ר lengthen the vowel (בֵּירֵךְ, תֵּיאֵר, הִתְקָרֵא) and ה, ח, ע keep it short (מִיהֵר, שִׂיחֵק, הִתְנַהֵג).
- ר rejects the dagesh and nothing else. It takes a plain shva, and it leaves the pa'al future's cholam alone: יִדְרוֹשׁ, יִזְרוֹק, יִשְׂרוֹף.
- Third position adds a furtive patach in every binyan — לִפְתּוֹחַ, לְהִיפָּתֵחַ, לְהַשְׁמִיעַ — but only when the preceding vowel is not already a, which is why נִפְתָּח, מְפוּתָּח and מוּשְׁמָע have none.
- The feminine participle is ־ַחַת / ־ַעַת in six binyanim — פּוֹתַחַת, נִפְתַּחַת, מְפַתַּחַת — and reverts to ־ָה only in hif'il: מַשְׁמִיעָה.
- The consonants are inaudible in Israeli speech; every vowel effect on this page is not.

- Gutturals (א ה ח ע ר) and What They Do to a PatternB1 — The gutturals are not a list of exceptions to memorise — they are one conspiracy with three heads. Each of these letters refuses something an ordinary consonant does, and every irregular form you will meet is the pattern rearranging itself around that refusal.
- Why בירך but דיבר: Where the Dagesh Is CompensatedC1 — Five letters refuse the dagesh that defines pi'el, and they do not all react the same way: א and ר lengthen the vowel in front of them, while ה, ח and ע leave it short. That single split explains a set of spellings and readings that otherwise look arbitrary.
- Chataf Vowels under the GutturalsB1 — א ה ח ע refuse a mobile shva and take a compound sign instead — and that one fact is why לאכול has three syllables, why the ל of לעבוד is la- and the ל of לסגור is li-, and why a whole class of verbs conjugates differently.
- Pa'al with a Guttural Second Radical (שאל, בחר, נהג)B1 — A guttural in the middle of the root does two things: it puts a short chataf vowel wherever the pattern would put a bare shva, and it forces the future's theme vowel to patach — יִשְׁאַל, יִבְחַר. The infinitive keeps its cholam, and that mismatch is what learners get wrong.
- שלמים: The Sound Root in Every BinyanB1 — A root with no weak letter behaves identically in all seven binyanim — which makes it the control case. Here is one grid, two roots, and the honest gaps in both, so that every weak class on the pages that follow can be read as a documented deviation from this.
