Qal Infinitive Absolute — Strong Roots

The IA has one invariable form per root. It does not inflect for person, number, or gender, and it cannot take preposition prefixes or pronominal suffixes.

Root IA Form Pattern Notes
שמר (guard) שָׁמ֣וֹר qamets + holem-waw + final cons. Strong A-class; cf. IC שְׁמֹר (shewa)
כתב (write) כָּת֣וֹב qamets + holem-waw Strong A-class
זכר (remember) זָכ֕וֹר qamets + holem-waw Imperatival IA: Exo 20:8
פקד (visit) פָּקֹ֨ד qamets + holem (no waw) Some strong IAs lack the waw; holem only
גאל (redeem) גָּאֹ֖ל qamets + holem Leviticus legal formulas
אבד (perish) אָבֹ֖ד qamets + holem Threat formula in Deuteronomy

Key marker: Strong IA = qamets under R1 + holem (±waw) on R2. Contrast IC: shewa under R1 + holem. The vowel under R1 is the primary diagnostic.


Strong B-class (Guttural R3)

Root IA Form Notes
שמע (hear) שָׁמ֣וֹעַ Qamets + holem-waw + patach before gutt. R3 (ע)
ידע (know) יָדֹ֣עַ Qamets + holem + patach at R3 (ע) — I-י retains y-shape
שלח (send) שָׁלֹ֖חַ Patach before gutt. ח at R3

Qal Infinitive Absolute — III-ה Roots

The final ה is retained in the IA (contrast the IC, where ה → וֹת):

Root IA Form Notes
ראה (see) רָאֹ֣ה ה retained; qamets + holem
עשה (do) עָשׂ֑וֹה / עָשׂ֥וֹ ה sometimes dropped; qamets + holem-waw
היה (be) הָי֧וֹ ה retained
הלך (go) הָל֣וֹךְ I-י root; IA retains full form (contrast IC לֶ/כֶת)
ענה (answer) עָנ֥וֹה ה retained
בנה (build) בָּנ֥וֹה ה retained

Key marker: III-ה IA ends in ה (or occasionally drops it). Contrast III-ה IC: ends in וֹת (holem-waw + taw). This ה/וֹת distinction is one of the clearest IA vs. IC diagnostics for III-ה roots.


Qal Infinitive Absolute — Biconsonantal

Biconsonantal IA forms are short and identical to the bare IC:

Root IA/IC Form Notes
מות (die) מ֥וֹת Most common IA in OT (49×); holem-waw + taw
שוב (return) שׁ֣וֹב Full shureq; IA = IC (distinguish by context: IA not preceded by preposition)
בוא (come) בּ֣וֹא Holem-waw; aleph quiesces
קום (arise) ק֣וּם Full shureq

Key marker: Biconsonantal IA is identical to the bare IC in form. The context distinguishes: IA is never preceded by a preposition and is typically paired with a finite verb of the same root.


Qal Infinitive Absolute — I-י

I-י roots retain their full IA form (the yod and its vowel are present), in contrast to the contracted IC:

Root IA Form IC Form Notes
הלך (go) הָל֣וֹךְ לֶ/כֶת IA = full qamets + holem-waw; IC = contracted seghol-taw
יצא (go out) יָצוֹא֙ צֵאת IA = yod shape; IC = tsere-aleph-taw
ידע (know) יָדֹ֣עַ לָ/דַ/עַת IA = qamets + holem + patach (gutt.); IC = patach-ayin-taw
ישב (sit) יָשׁ֥וֹב לָ/שֶׁ/בֶת IA retains yod; IC loses yod
ירד (go down) יָרֹ֣ד לָ/רֶ/דֶת

Key marker: I-י IA forms look like regular strong forms with the yod intact and qamets under R1. This distinguishes them sharply from the contracted I-י IC forms.


Qal Infinitive Absolute — I-נ

The nun is retained in I-נ IA forms (contrast IC where nun often drops or assimilates):

Root IA Form IC Form Notes
נתן (give) נָת֤וֹן תֵּת IA = both nuns visible; IC = both nuns drop
נסע (set out) נָס֣וֹעַ נְסֹ֣עַ IA = qamets + holem-waw
נפל (fall) נָפֹ֥ל נְפֹל Nun retained in both, but vowel differs

Key marker: I-נ IA retains the nun. The contrast with נתן's IC (תֵּת) is dramatic — the IA form (נָת֤וֹן) looks like a normal strong form.


Qal Infinitive Absolute — I-aleph

Root IA Form Notes
אכל (eat) אָכ֤וֹל Qamets under aleph + holem-waw
אמר (say) אָמ֤וֹר Qamets under aleph (contrast IC: hateph-seghol → אֱמֹר)
אהב (love) אָה֤וֹב
אסף (gather) אָס֤וֹף

Key marker: I-aleph IA has qamets under aleph (unlike the IC which has hateph-seghol). The holem-waw pattern on R2 is the same as strong A-class.
