Basics of Biblical Hebrew, Pratico & Van Pelt
Builds on Ch24 (Niphal Strong Verbs). Weak forms only — semantic functions not repeated.

Scope: This chapter extends the Niphal paradigm to five weak-root classes. Each class modifies the strong pattern in a predictable, phonologically motivated way. Functions (Passive / Reflexive / Reciprocal / Simple Action / Middle-Tolerative) were covered in Ch24 and are not repeated here.

1. The Eight Weak Classes — Overview

Key principle: None of these classes requires learning a new stem. Every change follows from a standard phonological rule — quiescence, compensatory lengthening, patach furtive, or assimilation — applied to the strong Niphal pattern. Learn the rule; the form follows.

2. III-א (Lamed-Aleph) Verbs

Pattern

The final א of the root quiesces (becomes silent) in word-final position. The vowel that would stand under it is drawn to the preceding syllable instead, often producing a final long vowel. The Niphal prefix and dagesh patterns are otherwise identical to the strong root.

Diagnostic markers:
- Perfect 3ms: נִמְצָא — looks like the strong root except the final vowel extends under א (which is silent)
- Imperfect/Wayyiqtol: יִמָּצֵא — the final syllable ends in silent א after tsere; the form looks like a strong root
- Participle ms: נִמְצָא — identical in pointing to the perfect 3ms; context distinguishes them

Key Corpus Examples

• נִמְצָא (Gen 44:9) — "whoever is found [with the cup]" — perfect 3ms; the silent א is invisible but the quiescence is real
• וַיִּמָּצֵא (Gen 44:12) — "and it was found" — wayyiqtol; classic passive in the Joseph narrative
• הִמָּצֵא יִמָּצֵא (Exo 22:3) — inf. absolute + imperfect; emphatic construction stressing the certainty of discovery
• אִם יִמָּצֵא (Gen 44:10) — imperfect 3ms; conditional clause in the brothers' oath

3. III-ה (Lamed-He) Verbs

Pattern

The final ה of these roots is not a true consonant but a vowel letter (mater lectionis). The Niphal of III-ה verbs shows distinctive contracted endings throughout the paradigm. The main patterns to learn:

Diagnostic markers:
- Perfect 3ms: נִגְלָה — final ָה (qamets + he) instead of the strong root's final consonant
- Imperfect 3ms: יִגָּלֶה — final seghol + he instead of tsere; the dagesh pattern is the same as the strong root
- Wayyiqtol 3ms: וַיִּגָּל — the ה is apocopated (dropped) in this form; compare וַיִּקָּטֵל → וַיִּגָּל
- Inf. Construct: הִגָּלוֹת — the ת is added to the base (cf. Qal inf. construct of III-ה roots)
- Participle ms: נִגְלֶה — final seghol + he

Paradigm Summary (3ms per conjugation)

Note on רָאָה: The I-ר does not take the normal dagesh pattern, so where גָּלָה shows יִגָּלֶה, רָאָה shows יֵרָאֶה (compensatory lengthening before ר). Both are III-ה; the difference is the I-position consonant.

Key Corpus Examples

• וַיֵּרָא יְהוָה אֶל־אַבְרָם (Gen 12:7) — wayyiqtol 3ms; apocopated form — the LORD appeared to Abram
• תֵרָאֶה הַיַּבָּשָׁה (Gen 1:9) — imperfect/jussive 3fs; let the dry land appear (tolerative)
• נִגְלָה כְּבוֹד יְהוָה (Isa 40:5) — perfect 3ms; the glory of the LORD will be revealed
• לְהֵרָאוֹת אֶת־פְּנֵי (Exo 34:24) — inf. construct; to appear before the LORD three times a year

4. I-guttural (Pe-Guttural) Verbs

Pattern

Guttural consonants (א ה ח ע) cannot receive dagesh forte. In the conjugations where the Niphal normally doubles R1 (imperfect, wayyiqtol, imperative, infinitives), the dagesh is rejected and the preceding vowel is lengthened compensatorily instead: hiriq → tsere (יִ → יֵ / הִ → הֵ).

In the perfect, the guttural takes a composite shewa (hateph) instead of a simple vocal shewa, and the prefix vowel often shifts to seghol (נִ → נֶ).

Diagnostic markers:
- Perfect 3ms: נֶאֱמַר / נֶעֱמַד — seghol under נ + composite shewa under the guttural
- Imperfect 3ms: יֵאָמֵר / יֵעָמֵד — tsere under the prefix (not hiriq); no dagesh in R1
- Wayyiqtol 3ms: וַיֵּאָמֵר — same lengthening; the tsere is the marker
- Imperative/Inf. Construct: הֵאָמֵר / הֵעָמֵד — tsere under ה (not hiriq); no dagesh in R1

Paradigm Summary (3ms per conjugation)

→ Full PGN tables: niphal-weak-pe-guttural-paradigms.md

Key Corpus Examples

• וַיֵּאָמֵר (Gen 10:9; etc.) — wayyiqtol 3ms of אָמַר; "it was said" — extremely frequent
• נֶאֱמַר (various legal texts) — perfect; "it has been said / it is written"
• הֵעָמֵד (cf. Exo 9:16) — imperative; "set yourself / be made to stand"
• נֶאֱסְפוּ (Gen 49:1) — perfect 3cp of אָסַף (I-א); "gathered together" — א rejects dagesh, seghol under נ

5. I-נ (Pe-Nun) Verbs

Pattern

In I-נ roots, the root's own first radical (נ) assimilates into R2 in the same conjugations where it would assimilate in a regular verb. Because the Niphal also has a נ prefix that assimilates in the imperfect/wayyiqtol/imperative/infinitives, both assimilations converge in those forms:

• Perfect: The Niphal נִ prefix stays (no assimilation in the perfect), but the root's own R1 (נ) also assimilates into R2 → R2 shows dagesh. The form appears to have only two root letters visible.
• Imperfect/Wayyiqtol/Imperative/Inf.: The Niphal prefix נ and the root's נ both assimilate into R2 → still a single dagesh in R2.

The result: I-נ Niphal forms consistently show dagesh forte in R2, with R1 (נ) invisible throughout the paradigm.

Diagnostic markers:
- Perfect 3ms: נִגַּשׁ (from נָגַשׁ) — only two consonants visible after the נִ prefix; dagesh in R2
- Imperfect 3ms: יִגַּשׁ — looks like a Qal imperfect; the dagesh in R2 is the Niphal signal
- Wayyiqtol 3ms: וַיִּגַּשׁ — same; compare to strong וַיִּקָּטֵל (dagesh in R1) vs. I-נ (dagesh in R2)
- Participle ms: נִגָּשׁ — qamets under R2 (like the strong root participle, but only two consonants visible)

Paradigm Summary (3ms per conjugation)

→ Full PGN tables: niphal-weak-pe-paradigms.md (Part 1 — I-נ)

Key Corpus Examples

• וַיִּגַּשׁ יְהוּדָה (Gen 44:18) — wayyiqtol 3ms of נָגַשׁ; "Judah drew near" — one of the most frequent Niphal wayyiqtol forms in Genesis
• וַיִּנָּצֵל יַעֲקֹב (Gen 32:31) — wayyiqtol 3ms of נָצַל; "Jacob was delivered" — after the wrestling at Peniel
• הִנָּצֵל (Prov 6:3) — imperative; "deliver yourself!" — reflexive force of the Niphal clear
• נִצַּלְתֶּם (Exo 12:27) — perfect 2mp of נָצַל; "you were passed over / spared"

6. I-י (Pe-Yod) Verbs

Pattern

I-י verbs show the most complex split of the five classes, creating two distinct sub-paradigms within the same stem:

This is the only Niphal weak class with a split inside the paradigm. The נוֹ- forms can resemble Qal active participles of I-י roots — vowel under R2 distinguishes them (tsere = Qal participle; patah/qamets = Niphal perfect/participle).

Diagnostic markers:
- Perfect 3ms: נוֹלַד / נוֹדַע — the נוֹ prefix is the immediate marker; patah under R2 (not tsere)
- Imperfect 3ms: יִוָּלֵד / יִוָּדַע — יִוָּ cluster is distinctive; tsere or patah under R2 reflects the root's vowel class
- Wayyiqtol 3ms: וַיִּוָּלֵד — the וַיִּוָּ cluster is visually unique and highly frequent in genealogies
- Participle ms: נוֹלָד / נוֹדָע — נוֹ prefix + qamets under R2 (cf. perfect: patah under R2)

Paradigm Summary (3ms per conjugation)

→ Full PGN tables: niphal-weak-pe-paradigms.md (Part 2 — I-י)

Key Corpus Examples

• כִּי נוֹלַד לוֹ (Gen 21:3) — perfect 3ms; "for a son has been born to him" — birth announcement formula
• וַיִּוָּלֵד לַחֲנוֹךְ (Gen 4:18) — wayyiqtol 3ms; antediluvian genealogical chain — the וַיִּוָּ cluster appears scores of times in genealogies
• יִוָּדַע יֹוסֵף (Gen 45:1) — imperfect/wayyiqtol context; "Joseph made himself known"
• נוֹדָע בִּיהוּדָה אֱלֹהִים (Psa 76:2) — participle ms; "God is known in Judah"
• בֶּן מֵאָה שָׁנָה בְּהִוָּלֶד לוֹ יִצְחָק (Gen 21:5) — inf. construct; "when Isaac was born to him"

7. III-ח/ע (Lamed-Guttural) Verbs

Pattern

Gutturals (ח and ע) at R3 prefer a-class vowels. In the Niphal, this produces two effects:

1. Patach furtive (פַּתַח גְּנוּבָה) appears before word-final ח/ע in open syllables — inserted between the preceding vowel and the guttural, and pronounced before it (הִשָּׁמַע = "hish-SHA-ma").
2. In shorter forms (wayyiqtol 3ms, imperative 2ms), the Niphal characteristic tsere (between R2 and R3) shifts to patach because the guttural prefers an a-class vowel.

Diagnostic markers:
- Perfect 3ms: נִשְׁמַע — patach furtive beneath final ע; the form looks like the strong root except the furtive patach is visible
- Imperfect 3ms: יִשָּׁמַע — patach under R3 (not tsere as in the strong root יִקָּטֵל); dagesh forte in R1 is unchanged
- Wayyiqtol 3ms: וַיִּשָּׁמַע — patach before final ח/ע; no patach furtive (form already short)
- Participle ms: נִשְׁמָע — patach furtive before final ח/ע in the ms form

Paradigm Summary (3ms per conjugation)

→ Full PGN tables: niphal-weak-lamed-guttural-paradigms.md

Key Corpus Examples

• נִשְׁמַע (Est 1:20) — "the decree will be heard throughout the kingdom" — perfect 3ms; patach furtive before final ע
• יִשָּׁמַע (Exo 28:35) — "its sound shall be heard when he goes into the Holy Place" — imperfect 3ms; patach before ע (not tsere)
• וַיִּשָּׁמַע (Gen 45:2) — "the sound was heard in Pharaoh's house" — wayyiqtol 3ms; patach before ע, no furtive
• נִשְׁמָע (Ecc 12:13) — "all has been heard" — participle ms; patach furtive signals the lamed-guttural

8. Biconsonantal (II-י/ו) Verbs

Pattern

Biconsonantal (Hollow) roots have only two true root consonants with a medial long vowel. In the Niphal, the hallmark pattern is the נָ prefix (qamets under נ) in the perfect and participle — in contrast to the normal נִ (hiriq) of the strong root. This single marker is the key to recognizing the biconsonantal Niphal.

In the imperfect, wayyiqtol, and imperative, the Niphal's prefix נ assimilates into R1 (dagesh forte in R1), as in all Niphal imperfects; the contracted root (R1 + medial vowel + R2) follows.

Diagnostic markers:
- Perfect 3ms: נָקוֹם / נָכוֹן — qamets under נ; the biconsonantal root's medial vowel letter (ו/י) visible
- Imperfect 3ms: יִקּוֹם — dagesh forte in R1 (Niphal assimilation) + contracted root; can resemble Qal — context is essential
- Participle ms: נָקוּם / נָכוּן — qamets under נ; same prefix as perfect 3ms

Paradigm Summary (3ms per conjugation)

→ Full PGN tables: niphal-weak-biconsonantal-paradigms.md

Key Corpus Examples

• נָכוֹן (Gen 41:32) — "the thing is fixed by God" — perfect 3ms from כּוּן; qamets under נ is the diagnostic marker
• נָכוֹן (Psa 51:12) — "restore to me a steadfast spirit" — same root, same pattern; extremely common in wisdom and psalmic poetry
• נָכוֹן (Psa 57:8) — "my heart is steadfast, O God" — participial use of נָכוֹן from כּוּן
• יִכּוֹן (Psa 93:2) — "your throne is established from of old" — imperfect 3ms; dagesh in כּ (R1) marks it as Niphal

9. Geminate (Ayin-Doubled, II=III) Verbs

Pattern

Geminate roots have R2 = R3 (e.g., סָבַב: ס-ב-ב; תָּמַם: ת-מ-מ). The doubled consonant can appear as dagesh forte in the doubled R2/R3 (the "heavy" form), or it may collapse with a long compensatory vowel (the "light" form). In the Niphal, the most important pattern is the perfect/participle, which shows the distinctive נָ prefix (qamets under נ) — the same marker as the Biconsonantal class.

Diagnostic markers:
- Perfect 3ms: נָסַב — qamets under נָ; resembles Biconsonantal (e.g., נָכוֹן from כּוּן), but the root has three consonants with R2=R3 instead of a hollow vowel letter
- Imperfect 3ms: יִסֹּב — dagesh forte in R2/R3 (ב written once but doubled) + holem
- Wayyiqtol 3ms: וַיִּסֹּב — וַיִּ prefix + dagesh in R2/R3
- Participle ms: נָסַב — identical to perfect 3ms; context is the only distinguisher (parallels Biconsonantal and III-א ambiguity)

Key Corpus Examples

• נָסַב (Josh 15:3) — "the border went around toward Azmon" — perfect 3ms; qamets under נָ is the primary diagnostic
• וַיִּסֹּב (1 Sam 7:16) — "and he went on circuit" — wayyiqtol 3ms; Samuel's annual judicial circuit; dagesh in ב marks the doubled root
• הִסֹּב (2 Sam 18:30) — "turn aside, stand here" — imperative 2ms; הִ prefix + dagesh in ב
• תִּתַּמָּה (†) — theoretically: "it shall be completed" — imperfect 3fs from תָּמַם; dagesh in מ marks R2=R3
• נָסַבּוּ (Josh 6:3) — "march around the city" — perfect 3cp; dagesh visible in ב with 3cp suffix
