Pa'al with a Guttural First Radical (עמד, חשב, חזר) | Hebrew Grammar

A pa'al root whose first letter is ע, ח or ה — ע־מ־ד stand, ח־שׁ־ב think, ח־ז־ר return, ע־ב־ד work — is regular in the past and in the present, and then does exactly one thing in the future and the infinitive: it changes the prefix vowel from i to a. לִכְתּוֹב becomes לַעֲמוֹד, יִכְתּוֹב becomes יַעֲמוֹד. Everything after the prefix is untouched. Learn to hear that syllable and the class is finished.

Almost nothing happens in the past or the present

Root	Past 3 m.sg	Present m.sg	Present f.sg	Present m.pl
ע־מ־ד stand	עָמַד amád	עוֹמֵד oméd	עוֹמֶדֶת omédet	עוֹמְדִים omdím
ח־שׁ־ב think	חָשַׁב khasháv	חוֹשֵׁב khoshév	חוֹשֶׁבֶת khoshévet	חוֹשְׁבִים khoshvím
ח־ז־ר return	חָזַר khazár	חוֹזֵר khozér	חוֹזֶרֶת khozéret	חוֹזְרִים khozrím
ע־ב־ד work	עָבַד avád	עוֹבֵד ovéd	עוֹבֶדֶת ovédet	עוֹבְדִים ovdím

The reason is worth a sentence, because it tells you where trouble can come from. A guttural refuses a mobile shva and refuses a doubling dot (gutturals), and in nearly every cell of these two tenses the first radical is asked for neither: it carries the pattern's own full vowel — kamatz in עָמַד, cholam in עוֹמֵד. Nothing is being demanded of it, so nothing bends.

The exception proves the rule, and it is one cell. In the אתם / אתן past, the careful pronunciation puts a mobile shva on the first radical — כְּתַבְתֶּם ktavtém — and a guttural cannot carry one, so Pealim prints עֲמַדְתֶּם amadtém and חֲשַׁבְתֶּם khashavtém with the usual chataf. Everyday Israeli pulls the stress back onto the stem in that form (katávtem, amádtem), which turns the shva into a full vowel and makes the question disappear before it is asked.

אני עומד בתור כבר עשרים דקות.

aní oméd batór kvar esrím dakót

I've been standing in line for twenty minutes. (m. speaker)

היא חוזרת הביתה מאוחר בימי שלישי.

hi khozéret habáyta me'ukhár biméi shlishí

She gets home late on Tuesdays.

עבדתי שם שנתיים ואז עזבתי.

avádti sham shnatáyim ve'áz azávti

I worked there for two years and then I left.

The future and the infinitive: ya- and la-

Root	Future 3 m.sg	Infinitive	Written
כ־ת־ב (regular, for comparison)	יִכְתּוֹב yikhtóv	לִכְתּוֹב likhtóv	יכתוב · לכתוב
ע־מ־ד	יַעֲמוֹד ya'amód	לַעֲמוֹד la'amód	יעמוד · לעמוד
ע־ב־ד	יַעֲבוֹד ya'avód	לַעֲבוֹד la'avód	יעבוד · לעבוד
ח־ז־ר	יַחֲזוֹר yakhazór	לַחֲזוֹר lakhazór	יחזור · לחזור
ח־שׁ־ב	יַחְשׁוֹב yakhshóv	לַחְשׁוֹב lakhshóv	יחשוב · לחשוב

Say the pairs out loud: likhtóv / la'amód, yikhtóv / ya'amód. That contrast — li-/yi- against la-/ya- — is the entire audible content of the class. Nothing else in the word has moved: the cholam is still there, the stress is still final, the root letters are all present and in order.

אני צריכה לעבוד עד מאוחר היום.

aní tsrikhá la'avód ad me'ukhár hayóm

I have to work late today. (f. speaker)

אין לי כוח לחשוב על זה עכשיו.

ein li kóakh lakhshóv al ze akhsháv

I don't have the energy to think about that right now.

אני לא בטוח שהוא יעמוד בלחץ.

aní lo batúakh shehú ya'amód balákhats

I'm not sure he'll hold up under the pressure. (m. speaker)

הם יחזרו רק בסוף החודש.

hem yakhazrú rak besóf hakhódesh

They won't be back until the end of the month.

Why a, and where the a came from

The usual explanation — "gutturals like the vowel a" — is true but backwards, and the honest version is more useful. The pa'al future prefix was originally *ya-, and Arabic, which never changed it, still says yaktubu "he writes". Hebrew reduced that a to i in the unstressed closed syllable, producing יִכְתּוֹב; next to a guttural the reduction did not go through. So יַעֲמוֹד is the conservative form and יִכְתּוֹב is the innovation — the guttural did not add anything, it prevented a loss.

💡

Do not read that a as vowel colouring, because it behaves differently. Colouring is what a guttural does from the middle or the end of a root, and there the four letters do not all act alike. Here nothing is being coloured at all — the prefix's original a is simply not being taken away — and ה, ח and ע are equally good at blocking that reduction, which is why ה־ר־ג gives לַהֲרוֹג laharóg right alongside לַעֲמוֹד. The same ה colours a theme vowel as well, but only from the middle: נ־ה־ג gives יִנְהַג. Two independent effects, easily confused.

The same prefix appears wherever else a pa'al future does, so the pattern is fully general: אֶעֱמוֹד, תַּעֲמוֹד, יַעֲמוֹד, נַעֲמוֹד. Two cells deserve a look.

	ע־מ־ד	ח־שׁ־ב	Written
אני	אֶעֱמוֹד e'emód	אֶחְשׁוֹב ekhshóv	אעמוד · אחשוב
אתה	תַּעֲמוֹד ta'amód	תַּחְשׁוֹב takhshóv	תעמוד · תחשוב
הוא	יַעֲמוֹד ya'amód	יַחְשׁוֹב yakhshóv	יעמוד · יחשוב
אנחנו	נַעֲמוֹד na'amód	נַחְשׁוֹב nakhshóv	נעמוד · נחשוב
הם	יַעַמְדוּ ya'amdú	יַחְשְׁבוּ yakhshevú	יעמדו · יחשבו

In the אני form the prefix vowel is a segol, not a patach, and the chataf under the guttural copies it: אֶעֱמוֹד, with a chataf-segol. The chataf is not a fixed sign — it is an echo of the vowel in front of it. And in the הם form the chataf has become a full patach, יַעַמְדוּ, because a chataf cannot stand immediately before a shva; the shortest vowel in the word has to be somewhere else. Both are set out on chataf vowels.

Chataf or plain shva? ע and ה always; ח either way

Compare לַעֲמוֹד with לַחְשׁוֹב. The first has a chataf-patach under the guttural, three syllables; the second has a plain silent shva, two syllables. There is no rule that predicts which, and this is where a textbook's tidy paradigm quietly misleads.

First radical	Behaviour	Verified forms
ע	always chataf-patach	לַעֲמוֹד · לַעֲבוֹד · לַעֲזוֹר
ה	always chataf-patach	לַהֲרוֹג
ח	varies by verb — and some verbs allow both	לַחְשׁוֹב · לַחְתּוֹךְ · but לַחֲזוֹר ~ לַחְזוֹר, לַחֲלוֹם ~ לַחְלוֹם

Pealim prints both vocalizations for ח־ז־ר and ח־ל־ם — lakhazór and lakhzór, lakhalóm and lakhlóm — and both are current in speech. What you cannot do is run it the other way: lakhashóv for לחשוב is not a variant, it is simply not a word.

💡

The imperative shows why ח is allowed a plain shva in the first place, and it is a satisfying piece of logic. In יַחְשׁוֹב the shva is silent, closing the syllable yakh- — and a guttural has no objection to a silent shva. But the imperative starts the word on the root, so the same shva would be mobile, and gutturals genuinely cannot carry that. The chataf therefore becomes obligatory even for ח: חֲשׁוֹבkhashóv, עֲמוֹדamód, חֲזוֹרkhazór. Two different refusals doing two different jobs in two different cells of the same verb.

Those short imperatives are neutral-to-formal; in ordinary speech Israelis reach for the future instead — תעמוד, תחשוב, תחזור.

תעמוד רגע, נפל לך משהו.

ta'amód réga, nafál lekhá máshehu

Hold on a second — you dropped something. (informal, to a man)

אני אחזור על זה עוד פעם, תקשיבו טוב.

aní ekhezór al ze od pá'am, takshívu tov

I'll go over it one more time — listen carefully.

Two roots that look like they belong here and do not

א־initial roots are a different class. א is a guttural, but א־כ־ל gives לֶאֱכוֹל le'ekhól with a segol prefix and a future יֹאכַל yokhál that has swallowed the א entirely. Do not extend la- to it. Those roots are on pa'al with א as first radical.

הלך begins with ה and still does not belong here. Its past and present are exactly what this page predicts — הָלַךְ, הוֹלֵךְ — and then the future and infinitive abandon the ה completely: יֵלֵךְ yelékh, לָלֶכֶת lalékhet, as though the root were י־ל־ך. That is the פ״י shape, not this one, and הלך has a page of its own.

The prefix story carries across the binyanim as well — נֶחְשַׁב, הֶעֱמִיד, הֶחְלִיט all show a guttural bending a prefix vowel that a regular root leaves alone (נִכְתַּב, הִדְלִיק) — and that picture is collected on gutturals across the gzarot.

Common Mistakes

1. Carrying the לכתוב prefix over to a guttural root. This is the transfer error, it is inaudible in writing, and it is the one thing on this page that will mark you out immediately.

❌ לעמוד, יעמוד

li'amód · yi'amód

Incorrect — a guttural first radical takes an a-prefix in the pa'al future and infinitive: la'amód, ya'amód. The unpointed spelling is identical either way, which is exactly why the error survives so long.

✅ אפשר לעמוד פה או שזה חוסם את המעבר?

efshár la'amód po o sheze khosém et hama'avár?

Can I stand here or is it blocking the way?

2. Extending ya-/la- to an א-initial root. Once the rule is learned it over-applies, and אכל and אמר are the first casualties.

❌ אני רוצה לאכול

la'akhól

Incorrect — א takes a segol prefix, not a patach: le'ekhól. The future is יֹאכַל yokhál, not ‘ya'akhól’.

✅ אני רוצה לאכול משהו לפני שנצא.

aní rotsé le'ekhól máshehu lifnéi shenetsé

I want to eat something before we head out.

3. Conjugating הלך by this page. The class's own logic predicts lahalókh, and the verb refuses.

❌ אני צריך להלוך

Incorrect — Modern Hebrew has no infinitive להלוך. הלך drops its ה and takes ללכת lalékhet, with a future ילך yelékh. (A rare biblical לַהֲלֹךְ does exist, in Ecclesiastes — which is exactly why the analogy feels right, and it is still not a form available to you.)

✅ אני צריך ללכת, מחכים לי בחוץ.

aní tsaríkh lalékhet, mekhakím li bakhúts

I have to go — they're waiting for me outside. (m. speaker)

4. Spreading the chataf to every verb in the class. לַעֲמוֹד is normally learned first, and its extra syllable then gets attached to ח verbs that do not take one.

❌ לחשוב

lakhashóv

Incorrect — Pealim gives לחשוב a plain silent shva under the ח, לַחְשׁוֹב, and prints no second vocalization for it: lakhshóv, two syllables. The chataf in לַעֲמוֹד and לַחֲזוֹר is real but lexical — it does not follow from the guttural, so it cannot be spread.

✅ אני צריך לחשוב על זה עוד קצת.

aní tsaríkh lakhshóv al ze od ktsat

I need to think about it a bit more. (m. speaker)

Key Takeaways

A pa'al root beginning ע, ח or ה is regular in the past and the present — עָמַד, עוֹמֵד, חָשַׁב, חוֹשֵׁב — apart from the אתם/אתן past, where the careful register takes a chataf (עֲמַדְתֶּם against כְּתַבְתֶּם).
The class lives in two cells only: the future and the infinitive swap the prefix from yi-/li- to ya-/la- — יַעֲמוֹד, לַעֲמוֹד, יַחְשׁוֹב, לַחְשׁוֹב.
The a is inherited, not added: Arabic still has yaktubu, and Hebrew reduced that vowel to i everywhere the guttural did not block it.
Under the guttural, ע and ה always take a chataf (לַעֲמוֹד, לַהֲרוֹג) while ח goes both ways — לַחְשׁוֹב but לַחֲזוֹר ~ לַחְזוֹר. The distribution is lexical; check the verb.
The chataf echoes the prefix vowel (אֶעֱמוֹד) and hardens to a full patach before a shva (יַעַמְדוּ).
In the imperative even ח must take the chataf — חֲשׁוֹב, עֲמוֹד — because there the shva would be mobile.
א־initial roots (לֶאֱכוֹל, יֹאכַל) and הלך (לָלֶכֶת, יֵלֵךְ) look like members and are not.
