Lesson 16: Binyan Nif'al (נִפְעַל) — passive and MIDDLE partner of Pa'al

Part 1: What Nif'al is and why it exists

In Lesson 7 you saw the map of the seven binyanim. In L8 and L12 we filled in Pa'al (active, basic) with the present and past tenses. In L13 came Pi'el (intensive/causative), in L14 — Hif'il (causative). Today — Nif'al, and this is a turning point: for the first time we build the passive/middle voice.

The key thing about Nif'al: it's the passive or MIDDLE partner of Pa'al. It takes the same root as Pa'al and flips the voice: where Pa'al says "he does", Nif'al says "it's done to him", "he becomes done", "it happens to him".

For an English speaker this works through the get-passive and middle voice: where Pa'al says "he builds", Nif'al says "it gets built", "it is built", "it happens":

Root	Pa'al (active)	Nif'al (middle/passive)
כ-נ-ס	כָּנַס — entered (rare)	נִכְנַס — entered ("went in, got in")
ש-מ-ר	שָׁמַר — guarded	נִשְׁמַר — was preserved, was kept
ב-נ-ה	בָּנָה — built	נִבְנָה — was being built, was built
מ-צ-א	מָצָא — found	נִמְצָא — is located, was located
פ-ג-ש	פָּגַשׁ — met (someone)	נִפְגַּשׁ — met up (with someone)

But! Not every Nif'al = pure passive. Many Nif'al verbs are stand-alone and translate as ordinary English verbs, sometimes without any passive flavor at all: ulai nichnasti = "maybe I went in / ended up inside" (not "was brought in"!). So Nif'al is a "middle voice" wider than "passive": passive, reflexive, inchoative ("become some way"), or just plain intransitive.

Nif'al is recognized by two signs

Past: prefix נִ- (ni-) at the start of the form. נִכְנַסְתִּי (nichnasti — "I entered"). Present: prefix נִ- or נְ- (ne-) + the pattern נִכְנָס / נִכְנֶסֶת (nichnas — "enters").

In both tenses the first root letter is pressed against a nun (the letter נ before the root). That's the binyan's mark.

Part 2: Past tense — the paradigm of נִכְנַס "enter"

Take the root כ-נ-ס "enter" and put it in Nif'al. The past tense in Nif'al is formed with the suffixes of the same persons as in Pa'al (L12), but the root is dressed in the frame נִ + Ca + Ca + Ca + suffix.

Person	Hebrew	Translit	Translation
ani (I)	נִכְנַסְתִּי	nichnasti	I entered
ata (you m.)	נִכְנַסְתָּ	nichnasta	you entered
at (you f.)	נִכְנַסְתְּ	nichnast	you entered
hu (he)	נִכְנַס	nichnas	he entered
hi (she)	נִכְנְסָה	nichnesa	she entered
anachnu (we)	נִכְנַסְנוּ	nichnasnu	we entered
atem (you m. pl.)	נִכְנַסְתֶּם	nichnastem	you (m. pl.) entered
aten (you f. pl.)	נִכְנַסְתֶּן	nichnasten	you (f. pl.) entered
hem (they m.)	נִכְנְסוּ	nichnesu	they (m.) entered
hen (they f.)	נִכְנְסוּ	nichnesu	they (f.) entered

Notice: the past-tense suffixes (-ti, -ta, -t, -∅, -a, -nu, -tem, -ten, -u) are the same as in Pa'al. The only difference is in the body of the word: instead of katavti ("I wrote"-style) — nichnasti. So once you've learned Pa'al, you've nearly learned Nif'al in the past: add a nun at the front and re-cut the vowels slightly.

Tip: the anchor form for the whole paradigm is the 3rd person m.sg. (nichnas, "he entered"). From it, like from a trunk, the suffixes grow.

Part 3: Present tense — the paradigm of נִכְנָס "enters"

In L8 you learned that the present tense in Hebrew is a participle with four forms by gender and number. Nif'al works the same way:

Person	Hebrew	Translit	Translation
m. sg.	נִכְנָס	nichnas	(he) enters
f. sg.	נִכְנֶסֶת	nichneset	(she) enters
m. pl.	נִכְנָסִים	nichnasim	(they m.) enter
f. pl.	נִכְנָסוֹת	nichnasot	(they f.) enter

Anchor: memorize nichnas / nichneset / nichnasim / nichnasot — and you'll recognize any Nif'al in the present. The pattern: niC₁C₂aC₃ / niC₁C₂eset / niC₁C₂asim / niC₁C₂asot, where C₁C₂C₃ are the three root letters.

Important nikkud nuance: in the past you often see the vowel chirik (י, "i") under the nun — נִ (ni-). In the present there's sometimes a sheva under the nun — נְ (ne-), but our anchor verb gives "i" in the present too (נִכְנָס). This is the typical picture: past → ni- (firm i), present → ni- / ne- (depending on the root).

Example in the matrix (question-answer)

— אַתָּה נִכְנָס לַחֶדֶר? — Ata nichnas la-cheder? — "Are you entering the room?" — כֵּן, אֲנִי נִכְנָס. — Ken, ani nichnas. — "Yes, I'm entering."

— הִיא כְּבָר נִכְנְסָה? — Hi kvar nichnesa? — "Has she already entered?" — לֹא, הִיא עֲדַיִן לֹא נִכְנְסָה. — Lo, hi adayin lo nichnesa. — "No, she still hasn't entered."

Part 4: Infinitive and dictionary form

Nif'al verbs are listed in the dictionary by infinitive, which begins with לְהִ- (le-hi-):

Infinitive	Translit	Translation
לְהִכָּנֵס	lehikanes	to enter
לְהִישָׁאֵר	lehisha'er	to stay, to remain
לְהִיוָּלֵד	lehivaled (often written leheavled)	to be born
לְהִיפָּגֵשׁ	lehipagesh	to meet (each other)
לְהִישָּׁמֵר	lehishamer	to be preserved, to take care
לְהִיבָּנוֹת	lehibanot	to be built
לְהִימָּצֵא	lehimatze	to be located
לְהֵרָאוֹת	lehera'ot	to look, to appear

Recognizable mark: the Nif'al infinitive always starts with לְהִ- or לְהֵ- (not לִ- like in Pa'al: לִכְתֹּב, לִקְרֹא). If you see lehi- or lehe- — it's Nif'al (or, less commonly, Hif'il, but that pattern is different, we'll cover it in L23).

Same-root Pa'al ↔ Nif'al pairs

The main trick for learning Nif'al vocab is to memorize in pairs: a familiar Pa'al + its Nif'al partner. That way the root stays on one semantic shelf, and the binyan sets the angle.

Root	Pa'al (active)	Nif'al (middle/passive)
כ-נ-ס	(no common Pa'al "entered"; modern speech uses Nif'al)	לְהִכָּנֵס lehikanes — to enter
ש-א-ר	(rare)	לְהִישָׁאֵר lehisha'er — to stay
י-ל-ד	לָלֶדֶת laledet — to give birth (of a mother)	לְהִיוָּלֵד lehivaled — to be born
פ-ג-ש	לִפְגֹּשׁ lifgosh — to meet (someone)	לְהִיפָּגֵשׁ lehipagesh — to meet (with someone)
ש-מ-ר	לִשְׁמֹר lishmor — to guard, to keep	לְהִישָּׁמֵר lehishamer — to be preserved, to be careful
ב-נ-ה	לִבְנוֹת livnot — to build	לְהִיבָּנוֹת lehibanot — to be built
מ-צ-א	לִמְצֹא limtzo — to find	לְהִימָּצֵא lehimatze — to be located
ר-א-ה	לִרְאוֹת lir'ot — to see	לְהֵרָאוֹת lehera'ot — to look (be visible)

Memory hack: Pa'al answers "who does it?", Nif'al — "what's happening to it / to whom". "I build a house" — livnot (Pa'al). "The house is being built" — lehibanot (Nif'al). "I found the key" — limtzo (Pa'al). "The key is on the table" — lehimatze (Nif'al).

Part 5: When Nif'al is passive vs. when it's a stand-alone verb

This is the trickiest moment of the lesson. Two scenarios.

Scenario A: Nif'al = passive (real, with an agent)

You can ask "by whom?" and the sentence stays alive:

הַסֵּפֶר נִכְתַּב עַל יְדֵי הַמּוֹרֶה. — Ha-sefer nichtav al-yedei ha-more. — "The book was written by the teacher."

Here Nif'al is the "mirror" of the Pa'al sentence "the teacher wrote the book". The agent is named explicitly (al-yedei — "by / through").

Scenario B: Nif'al = middle/stand-alone verb

There's no hidden "by whom"; the verb just describes a state or process that the subject is caught up in:

אוּלַי נִכְנַסְתִּי לַחֶדֶר הַלֹּא נָכוֹן. — Ulai nichnasti la-cheder ha-lo nachon. — "Maybe I walked into the wrong room."

Nobody is "bringing me in" — I went in / ended up inside on my own. This is the "middle voice": between active and passive, but not strictly reflexive.

Practical guideline: for an English speaker, roughly 70% of Nif'al verbs translate with a get-passive or a plain intransitive (is located, gets built, meet up, get born, is preserved, stays), and 30% with an ordinary verb (went in, looks, ended up). Don't memorize a rigid rule; learn the meaning of each verb individually.

Special case: lehera'ot "to look (appear)"

הִיא נִרְאֵית עֲיֵפָה הַיּוֹם. — Hi nir'eit ayefa ha-yom. — "She looks tired today."

This is a classic Nif'al that does NOT translate as a passive: nir'a = "looks, appears", literally "is seen". The root is the same as Pa'al lir'ot ("to see"), but the meaning is "to give the impression of, to appear a certain way".

Part 7: Comparing binyanim on one root

Take the root ש-מ-ר "guard" and put it in Pa'al and Nif'al — see clearly how a binyan switches the voice:

Binyan	Form (hu, past)	Translation	Who acts, who undergoes
Pa'al	שָׁמַר shamar	he guarded, kept	he is active, the object is what's being guarded
Nif'al	נִשְׁמַר nishmar	was preserved, was kept	it has something happen to it — it was preserved

הַחַיָּל שָׁמַר עַל הָעִיר. — "The soldier guarded the city." (Pa'al — active.) הָעִיר נִשְׁמְרָה מִן הָאוֹיֵב. — "The city was preserved / was kept safe from the enemy." (Nif'al — passive/middle.)

The same logic on the root ב-נ-ה:

הַפּוֹעֵל בָּנָה בַּיִת. — "The worker built a house." (Pa'al) הַבַּיִת נִבְנָה בְּשָׁנָה. — "The house was built in a year." (Nif'al)

Principle: by changing the binyan, you don't change the root and topic — you change the angle of view. Pa'al puts the doer in the center, Nif'al — the process or result.
