Basics of Biblical Hebrew, Pratico & Van Pelt
Builds on Ch15 (Qal Imperfect Strong Verbs). Weak forms only.

Scope: This chapter extends the Qal Imperfect paradigm to eight weak-root classes,
and also introduces the Wayyiqtol (sequential past Imperfect) and the short Imperfect
(Jussive) as they appear in weak roots. Each class modifies the strong pattern through
predictable phonological rules.

1. The Eight Weak Classes: Overview

Key principle: The Imperfect is where most weak-class effects are most visible.
The Perfect was largely regular for I-נ, I-י, and I-guttural; here those classes
produce major, highly recognizable changes.

2. III-א (Lamed-Aleph)

Pattern

In the Imperfect, the aleph at R3 generally quiesces (silent), and the preceding vowel
is retained or slightly lengthened. The forms are close to the strong Imperfect but with
the silent aleph ending:

• 3ms: יִמְצָא (tsere-aleph or patach-aleph — qamets replaces patach in some forms)
• The aleph is present in writing but silent in pronunciation

Diagnostic Markers

• 3ms/3fs/1cs: ends in silent א; preceding vowel often qamets
• 3mp: מְצְאוּ- or similar; aleph at end
• Short Jussive: same as long form (no shortening for III-א)

Paradigm Summary

→ Full paradigm: qal-imperfect-weak-lamed-aleph-paradigms.md

Corpus Examples

• Gen 8:9 — וְלֹא־מָצְאָה הַיֹּונָה (Perfect — contrast with Imperfect)
• Exo 5:11 — אַשֶׁ֣ר תִּמְצָ֑אוּ — "that you find" (2mp Imperfect with patach-aleph ending)

3. III-ה (Lamed-He)

Pattern

This is the most important weak class for the Imperfect. The He at R3 appears as
-ֶה (seghol + he) in the long Imperfect forms, and drops entirely in the
short Jussive and Wayyiqtol:

• Long Imperfect 3ms: יִבְנֶ֫ה, יַעֲשֶׂ֫ה, יִרְאֶ֫ה
• Short Jussive 3ms: יִ֫בֶן, יַ֫עַשׂ, יֵ֫רֶא (the ה drops; vowel shortens)
• Wayyiqtol 3ms: וַיִּבֶן, וַיַּ֫עַשׂ, וַיַּ֫רְא

Diagnostic Markers

• Long form: -ֶה ending on the Imperfect (seghol + vowel letter he)
• Short Jussive/Wayyiqtol: final ה absent; preceding vowel often seghol or patach
• 3fs/2ms long form: also -ֶה ending (same as 3ms)
• 2fs: תִּבְנִי (hireq-yod replaces the seghol-he)

Paradigm Summary — III-ה Imperfect

→ Full paradigm: qal-imperfect-weak-lamed-he-paradigms.md

Corpus Examples

• Gen 2:19 — וַיִּצֶר֩ יְהוָ֨ה — wayyiqtol of יצר (I-gutt.; for comparison)
• Gen 1:7 — וַיַּ֣עַשׂ אֱלֹהִ֔ים אֶת־הָרָקִ֑יעַ — "and God made" (wayyiqtol of עשה III-ה)
• Gen 2:22 — וַיִּ֣בֶן יְהוָ֘ה אֱלֹהִים֮ — "and the LORD God built" (wayyiqtol of בנה III-ה)
• Gen 3:1 — תַּעֲשֶׂ֑ה כִּ֤י — "that you do/make" (2ms/3fs long form; III-ה seghol-he ending)

4. III-ח/ע (Lamed-Guttural)

Pattern

The guttural at R3 cannot close a syllable cleanly. In the long Imperfect, a
patach furtive appears before the guttural in word-final open syllables (3ms, 3fs).
In the short Imperfect (Jussive), there is no furtive — the tsere shifts to patach
and the syllable is closed:

• Long 3ms: יִשְׁמַ֫עַ (patach furtive under guttural)
• Short Jussive 3ms: יִשְׁמַע (no furtive; the form shortens slightly)
• Wayyiqtol 3ms: וַיִּשְׁמַע (short form + waw prefix)

Diagnostic Markers

• Long form 3ms/3fs: patach furtive visible below and right of R2 vowel, before guttural
• Short/Wayyiqtol: guttural takes patach without furtive (syllable closed)

Paradigm Summary

Corpus Examples

• Gen 3:17 — כִּ֣י שָׁמַ֙עְתָּ֙ לְקֹ֣ול אִשְׁתֶּ֔ךָ — Perfect for contrast
• Exo 7:22 — וְלֹא־שָׁמַ֥ע אֲלֵהֶ֖ם פַּרְעֹ֑ה — "Pharaoh did not listen" (wayyiqtol/perfect 3ms; III-ע)

5. I-guttural (Pe-Guttural)

Pattern

The guttural at R1 cannot take dagesh forte and prefers composite shewa over vocal shewa.
In the Imperfect prefix, the prefix vowel shifts:

• Standard strong prefix: hireq under prefix consonant (יִקְטֹל)
• I-guttural: composite shewa (chateph-patach) under the guttural; the prefix vowel
  before it often shifts:
• Before ח/ה/ע with chateph-patach: prefix vowel → patach: יַעֲמֹד, יַחֲלֹם
• Before א (silent aleph): the aleph takes chateph-qamets or drops: יֶאֱהַב or יֱהִי

Diagnostic Markers

• Prefix vowel is patach (not hireq) when R1 is ח/ה/ע: יַעֲ–, יַחֲ–, יַהֲ–
• Chateph-patach under the guttural: יַחֲלֹם (not יִחְלֹם)
• אָמַר / אָכַל pattern: prefix may show patach or seghol depending on the aleph

Paradigm Summary

Note on אָמַר: The 3ms imperfect of אמר is יֹאמַר — the aleph has silent (quiescent)
behavior; the prefix takes a holem (not hireq). This is one of the highest-frequency verbs
in the Torah; this form must be memorized.

→ Full paradigm: qal-imperfect-weak-pe-guttural-paradigms.md

Corpus Examples

• Gen 1:3 — וַיֹּ֥אמֶר אֱלֹהִ֖ים — "and God said" (wayyiqtol of אמר; most common wayyiqtol in OT)
• Gen 2:16 — וַיְצַ֞ו יְהוָ֧ה — "and the LORD commanded" (Piel wayyiqtol; I-gutt. pattern)
• Gen 12:1 — וַיֹּ֤אמֶר יְהוָ֔ה — another instance of the dominant I-gutt. wayyiqtol

6. I-נ (Pe-Nun)

Pattern

This is one of the most dramatic weak-class effects in the entire Imperfect paradigm.
The nun at R1 assimilates into the following consonant by dagesh forte whenever
it would otherwise be in a non-syllable-opening position (i.e., before a consonant):

• 3ms Imperfect: יִנְתֹּן → יִתֵּן (nun assimilates into ת; tsere lengthens)
• 3ms of נָפַל: יִנְפֹּל → יִפֹּל
• Wayyiqtol: וַיִּתֵּן (dagesh in ת), וַיִּפֹּל (dagesh in פ)
• Forms with suffix (2fs, 3mp, etc.): nun assimilation applies throughout: תִּתְּנִי

Diagnostic Markers

• Dagesh forte in R2 (not R1) where the strong root would have R1-shewa + R2
• Tsere or holem under what appears to be R1 (but is actually the prefix + assimilated nun)
• Jussive 3ms: יִתֵּן (assimilation present; same as long Imperfect for I-נ)

Paradigm Summary

Nun is invisible but its effect (dagesh) is everywhere. When you see an unexpected
dagesh forte in R1 of what appears to be a regular Imperfect prefix, suspect I-נ assimilation.

Corpus Examples

• Gen 1:29 — הִנֵּה נָתַ֫תִּי לָכֶם (Perfect — compare with Imperfect יִתֵּן)
• Gen 2:16 — מִכֹּ֥ל עֵֽץ הַגָּ֖ן אָכֹ֥ל תֹּאכֵֽל (I-gutt.; for comparison)
• Gen 9:3 — כְּיֶ֣רֶק עֵ֔שֶׂב נָתַ֥תִּי לָכֶ֖ם (perfect; imperfect is יִתֵּן)
• Gen 4:12 — תִּתֵּן לְךָ הָאָרֶץ אֶת יְבוּלָהּ — "the ground shall not yield its strength to you" (3fs Imperfect of נתן)

7. I-י (Pe-Yod)

Pattern

The yod at R1 contracts with the prefix vowel in the Imperfect, producing a
distinctive pattern:

• Most I-י verbs: prefix takes tsere (not hireq); yod drops → יֵלֵד, יֵדַע
• Some I-י verbs follow a hollow pattern: יָשַׁב → יֵשֵׁב (tsere under prefix + tsere under R2)
• Wayyiqtol: וַיֵּ– pattern (waw + dagesh + tsere under prefix)
• Imperative (Ch18): the yod pattern will produce distinctive 2ms forms

Diagnostic Markers

• Tsere under prefix consonant (instead of hireq): יֵלֵד, יֵדַע, יֵשֵׁב
• Waw-consecutive: וַיֵּלֶד, וַיֵּדַע
• No yod at R1 in the Imperfect — the yod is replaced by the vowel pattern

Paradigm Summary

Corpus Examples

• Gen 4:17 — וַיֵּ֤דַע קַ֙יִן֙ — "and Cain knew" (wayyiqtol of ידע I-י)
• Gen 4:18 — וַיִּוָּלֵד לַחֲנֹוךְ — (Niphal wayyiqtol of ילד; contrast with Qal וַיֵּלֶד)
• Gen 21:3 — וַיִּקְרָ֨א אַבְרָהָ֜ם — (I-gutt.; for comparison of prefix patterns)

8. Biconsonantal (II-י/ו)

Pattern

The middle vowel letter of biconsonantal roots produces a distinctive Imperfect pattern:

• Long vowel under prefix consonant: יָקוּם (qamets = lengthened holem under prefix)
• The "long" Imperfect form has no R2 consonant — the middle vowel fills that position:
  יָקוּם (from קוּם), יָבוֹא (from בּוֹא), יָשׁוּב (from שׁוּב)
• Wayyiqtol 3ms: וַיָּ– pattern: וַיָּקׇם, וַיָּבֹא, וַיָּשָׁב
• Short Jussive: long vowel shortens: יָקׇם → יָקׄם (qamets hatuf)

Diagnostic Markers

• Qamets under prefix consonant (not hireq): יָקוּם, יָבוֹא — the "lengthened" prefix
• No R2 consonant between prefix and the long vowel (ו or י as vocalic element)
• Wayyiqtol: וַיָּ– prefix with qamets under the doubled prefix consonant

Paradigm Summary

→ Full paradigm: qal-imperfect-weak-biconsonantal-paradigms.md

Corpus Examples

• Gen 19:1 — וַיָּבֹ֙אוּ֙ שְׁנֵ֣י הַמַּלְאָכִ֔ים — "and the two angels came" (wayyiqtol 3mp of בּוֹא)
• Gen 22:3 — וַיָּ֣קׇם אַבְרָהָ֗ם — "and Abraham arose" (wayyiqtol 3ms of קוּם)
• Gen 14:17 — וַיֵּצֵא֩ מֶ֨לֶד סְדֹ֜ם — (I-י wayyiqtol; for contrast)

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

Pattern

In the Imperfect, the geminate root shows the doubled consonant with dagesh forte
when the syllable structure allows it, and a distinctive vowel:

• 3ms: יָסֹב (holem; "lengthened" prefix qamets) or יִסֹּב (hireq prefix + holem + dagesh forte in R2)
• Some Geminate Imperfect 3ms forms look similar to Biconsonantal — root knowledge required
• Wayyiqtol 3ms: וַיָּסֹב (qamets under prefix, holem under R2)

Diagnostic Markers

• Dagesh forte in the doubled consonant (R2 = R3): יִסֹּב, יִתְמֹּם
• Or short contracted form without visible dagesh in final position: יָסֹב (with qamets)
• Biconsonantal confusable: both classes can show qamets under prefix + short root;
  root knowledge is required

Corpus Examples

• Num 32:13 — וַיַּ֤נַּע אֹתָם֙ — (Hiphil; Geminate context)
• Deut 2:15 — עַד תֻּמָּ֖ם — "until they were finished" (Qal inf. const. of תמם; contrast with imperfect)

10. High-Frequency Weak Lemmas — Torah Qal Imperfect

Source: MACULA Hebrew WLC, Genesis–Deuteronomy, Qal Imperfect (yiqtol) tokens. Weak roots only.

Note on לָקַח (take): This verb follows I-guttural patterns in the Imperfect in
a special way: the lamed is actually a I-ל verb with irregular forms. The Imperfect
3ms is יִקַּח — the lamedh drops, the qoph takes dagesh. This must be memorized.

Note on הָלַך (walk): The Imperfect 3ms is יֵלֵךְ — the he drops and a tsere
prefix pattern emerges (similar to I-י). This is also a special case to memorize.
