Pa'al פ״נ: The Disappearing נ (נפל, נסע, נגע) | Hebrew Grammar

פ״נ is the class of pa'al roots whose first letter is נ: נ־פ־ל fall, נ־ס־ע travel, נ־ג־ע touch, נ־ת־ן give. It holds some of the highest-frequency verbs in the language, so a learner meets it in the first month and only meets its name much later. The pattern is simple where it counts and genuinely unpredictable in one cell, and this page keeps those two facts apart.

Past and present: the נ is right there

Root	Past 3 m.sg	Present m.sg	Present f.sg	Present m.pl
נ־פ־ל fall	נָפַל nafál	נוֹפֵל nofél	נוֹפֶלֶת nofélet	נוֹפְלִים noflím
נ־ס־ע travel	נָסַע nasá	נוֹסֵעַ noséa	נוֹסַעַת nosá'at	נוֹסְעִים nos'ím
נ־ג־ע touch	נָגַע nagá	נוֹגֵעַ nogéa	נוֹגַעַת nogá'at	נוֹגְעִים nog'ím
נ־ת־ן give	נָתַן natán	נוֹתֵן notén	נוֹתֶנֶת noténet	נוֹתְנִים notním

Nothing weak has happened yet. In both tenses the נ carries a full vowel of its own, and a consonant with a vowel has no reason to disappear.

נפלתי על המדרכה ושברתי את המשקפיים.

nafálti al hamidrakhá veshavárti et hamishkafáyim

I fell on the pavement and broke my glasses.

אנחנו נוסעים לצפון בסוף השבוע.

anákhnu nos'ím latsafón besóf hashavúa

We're driving up north this weekend.

אני נותן לך את המפתחות, אל תאבד אותם.

aní notén lekhá et hamaftekhót, al te'abéd otám

I'm giving you the keys — don't lose them. (m. speaker, to a man)

The future: the נ is absorbed, and you can hear it

The future prefix leaves the נ with no vowel of its own, squeezed against the second radical — and a vowelless נ does not survive that. It assimilates completely into the following consonant, which then carries a dagesh chazak, the doubling dot.

Root	Future 3 m.sg	Written	Sounds like
נ־פ־ל	יִפֹּל	ייפול	yipól — hard p
נ־ס־ע	יִסַּע	ייסע	yisá
נ־ג־ע	יִגַּע	ייגע	yigá
נ־ת־ן	יִתֵּן	ייתן	yitén

💡

The dagesh is not a decoration — in a begadkefat letter it changes the consonant outright. The פ of יִפֹּל carries the dot the vanished נ left behind, so the future of נפל is yipól and never yifól. This is the one place where a learner's ear can verify a piece of morphology directly: if you hear a p where the present tense had an f, a נ has been absorbed.

Two spelling notes go with that table. The unpointed forms are written with two yods — ייפול, ייסע, ייגע, ייתן — because Academy ktiv male writes a chirik with a yod whenever it stands before a doubled consonant. And the doubling itself is invisible in ordinary text, so ייתן on a page gives no hint that a נ was ever there.

אל תדאג, זה לא ייפול.

al tid'ág, ze lo yipól

Don't worry, it isn't going to fall. (informal, to a man)

אני אתן לך תשובה עד מחר.

aní etén lekhá tshuvá ad makhár

I'll give you an answer by tomorrow. (to a man)

ניסע ברכבת, זה יותר מהיר.

nisá barakévet, ze yotér mahír

Let's take the train, it's faster.

The infinitive is not predictable. Check it verb by verb

This is where the class stops being a rule. Four of its commonest members give four different infinitives, and there is no property of the root that tells you which one you are getting.

Root	Past	Present	Future	Infinitive	What happened to the נ
נ־פ־ל	נָפַל	נוֹפֵל	יִפֹּל · ייפול	לִפֹּל · ליפול	absorbed, as in the future
נ־ס־ע	נָסַע	נוֹסֵעַ	יִסַּע · ייסע	לִנְסוֹעַ · לנסוע	kept, fully written and pronounced
נ־ג־ע	נָגַע	נוֹגֵעַ	יִגַּע · ייגע	לָגַעַת	dropped, and a ־ַת ending added
נ־ת־ן	נָתַן	נוֹתֵן	יִתֵּן · ייתן	לָתֵת	both נ letters gone; the word contracts

Count the right-hand column: four verbs, four outcomes. Absorbed, kept, replaced by an ending, and contracted away entirely. Learn the infinitive as part of the verb, the way you already learn its gender agreement — there is no shortcut here, and pretending otherwise is what makes this class feel treacherous.

💡

נפל has two current infinitives, and Pealim prints them on the same entry: לִפֹּל / ליפול, the everyday form, and the classical לִנְפֹּל / לנפול with the נ restored, which is what you will meet in careful and formal writing. Both are correct — this is a register choice, not an error to be corrected in either direction. The future is the opposite case: there the נ has no formal alternative, and yinpól is simply not a Hebrew word.

אין לי כוח לנסוע עד תל אביב עכשיו.

ein li kóakh linsóa ad tel avív akhsháv

I don't have the energy to drive all the way to Tel Aviv right now.

אסור לגעת בתמונות בתערוכה.

asúr lagá'at batmunót bata'arukhá

You're not allowed to touch the pictures in the exhibition.

הוא נגע בנושא רק בסוף הפגישה.

hu nagá banosé rak besóf hapgishá

He only touched on the subject at the very end of the meeting.

נתן assimilates at the other end too

נ־ת־ן has a נ in third position as well, and it behaves the same way whenever an ending squeezes it: it merges into the consonant that follows.

Form	Pointed	Written	Reading
I gave	נָתַתִּי	נתתי	natáti — the root's נ has gone into the ת of the ending
we gave	נָתַנּוּ	נתנו	natánu — merged with the נ of ־נוּ, stress on the middle
they gave	נָתְנוּ	נתנו	natnú — no merger, stress on the end

The last two rows are the same three letters on the page. נתנו is both "we gave" and "they gave", and nothing but the stress separates them: natánu against natnú. Context settles it in practice, but this is a real ambiguity of written Hebrew and not a trick question.

נתנו לנו הנחה כי חיכינו הרבה.

natnú lánu hanakhá ki khikínu harbé

They gave us a discount because we'd waited so long.

A dagesh does not prove there was a נ

Here is the piece of reasoning that separates a learner who has memorised the class from one who understands it. Faced with הִצִּיעַ "he suggested" — a hif'il with a doubled צ and no visible first radical — the obvious move is to reconstruct the root as נ־צ־ע, on the model of הִגִּישׁ from נ־ג־שׁ. That is wrong. The root is י־צ־ע.

A dagesh chazak proves that some consonant was absorbed. It does not say which one, and י assimilates in exactly the same way as נ. Hebrew grammars give these roots a class of their own, גזרת חפי״צ — roots whose first letter is י and whose second is צ, plus two with ז: י־צ־ב, י־צ־ג, י־צ־ע, י־צ־ק, י־צ־ר, י־צ־ת, י־ז־ם, י־ז־ע.

The proof is that the yod comes back. Put one of these roots into pi'el or hitpa'el, where nothing squeezes the first radical, and there it is: לְיַיצֵּג leyatség "to represent" (י־צ־ג), לְהִתְיַיצֵּב lehityatsév "to report, to present oneself" (י־צ־ב). No genuine פ״נ root ever does that — you will never find a pi'el of נ־פ־ל with a נ that behaves like the yod in לייצג, because the נ of נפל never left in the first place. If the missing letter resurfaces as a yod, it was a yod.

נגש: the sources disagree

נִגַּשׁ nigásh "he approached", with its infinitive לָגֶשֶׁת lagéshet, is filed by Pealim as a pa'al פ״נ verb. Classical grammars analyse the same forms as nif'al, and the present tense נִגָּשׁ nigásh does have the nif'al shape. Both analyses are defensible and both are in print; what matters for using the verb is that its forms are agreed on. Take the label as an open question rather than something to memorise one way.

ניגשתי אליו ושאלתי אם הוא צריך עזרה.

nigáshti eláv vesha'álti im hu tsaríkh ezrá

I went up to him and asked if he needed help.

The same assimilation runs through the other binyanim — הִגִּיעַ, הִגִּישׁ, הִכִּיר in hif'il, נִכְנַס in nif'al — and that picture is on פ״נ across the binyanim and hif'il פ״נ.

Common Mistakes

1. Restoring the נ in the future. You know the root is נ־פ־ל, so you write the נ. The future is the one place it cannot go.

❌ אני מפחד שהוא ינפול

Incorrect — the נ assimilates into the פ in the future: אני מפחד שהוא ייפול, yipól. There is no form ‘yinpól’.

✅ אני מפחד שהוא ייפול מהאופניים.

aní mefakhéd shehú yipól meha'ofanáyim

I'm worried he'll fall off the bike. (m. speaker)

2. Reading the doubled letter as a soft one. The dot is the whole point, and it is invisible in ordinary spelling.

❌ ייפול

yifól

Incorrect — the dagesh left by the absorbed נ hardens the letter: yipól. Compare the present נוֹפֵל nofél, where the פ is soft because there is nothing doubling it. נפל is the one member of the class where you can hear this at all, since only ב, כ and פ still have two sounds in Israeli Hebrew — the ת of ייתן is a t either way.

3. Building the infinitive from the class instead of from the verb. Four members, four shapes — the class does not decide this.

❌ אני רוצה לנתון לך משהו

Incorrect — there is no such infinitive. נתן contracts all the way to לָתֵת: אני רוצה לתת לך משהו.

✅ אני רוצה לתת לך משהו קטן לדרך.

aní rotsé latét lekhá máshehu katán ladérekh

I want to give you something small for the road. (to a man)

4. Reconstructing a נ from a dagesh. This one costs you the dictionary entry, not just the form.

❌ הציע ← השורש נ־צ־ע

Incorrect — the root is י־צ־ע. A dagesh shows that something was absorbed, and yod assimilates just as nun does. Look up י־צ־ע and the entry is there; look up נ־צ־ע and there is nothing.

Key Takeaways

פ״נ = a pa'al root beginning with נ, and it holds some of the most frequent verbs in Hebrew: נפל, נסע, נגע, נתן.
The נ is fully present in the past and the present — נָפַל, נוֹפֵל — because it has a vowel of its own there.
In the future it is absorbed into the second radical, leaving a dagesh: יִפֹּל, יִסַּע, יִגַּע, יִתֵּן, written ייפול, ייסע, ייגע, ייתן.
The dagesh is audible: יִפֹּל is yipól with a hard p, against the present nofél with a soft one.
The infinitive is not predictable from the class — לִפֹּל, לִנְסוֹעַ, לָגַעַת, לָתֵת are four different outcomes and must be learned per verb. נפל has both לִפֹּל and the more formal לִנְפֹּל.
נתן also assimilates its final נ: נָתַתִּי, and נָתַנּוּ natánu "we gave" against נָתְנוּ natnú "they gave" — both written נתנו.
A dagesh does not prove a נ. הִצִּיעַ is י־צ־ע (גזרת חפי״צ), and the yod resurfaces in לְיַיצֵּג and לְהִתְיַיצֵּב.
נגש is classed as pa'al by Pealim and as nif'al by classical grammars; the forms are not in dispute, the label is.
