Qal Infinitive Construct — Strong Roots

The IC does not inflect for person, number, or gender. It has one form (plus variants with preposition/suffix).

Root Bare IC + לְ prefix + בְּ prefix + כְּ prefix
שמר (guard) שְׁמֹר לִ/שְׁמֹר בִּ/שְׁמֹר כִּ/שְׁמֹר
כתב (write) כְּתֹב לִ/כְתֹב בִּ/כְתֹב כִּ/כְתֹב
זכר (remember) זְכֹר לִ/זְכֹר בִּ/זְכֹר כִּ/זְכֹר

Key marker: Strong IC = shewa under R1 + holem on R2. Identical to Imperative 2ms. Preposition לְ takes hireq (לִ–) before the IC. Context distinguishes IC from Imperative.


With לְ Prefix

The preposition לְ (purpose, complementary, epexegetical) takes hireq before the IC:

Root class Root + לְ Transliteration
Strong A שמר לִ/שְׁמֹר li-shmor
Strong B (gutt. R3) שמע לִ/שְׁמֹ֣עַ li-shmo'a
Strong B (gutt. R3) זבח לִ/זְבֹּ֣חַ li-zbokh
III-ה ראה לִ/רְאוֹת li-r'ot
III-ה + I-gutt. עשה לַ/עֲשׂוֹת la-'asot
Biconsonantal בוא לָ/בֹא la-vo
Biconsonantal שוב לָ/שׁוּב la-shuv
I-י הלך לֶ/כֶת le-khet
I-י ישב לָ/שֶׁ/בֶת la-shevet
I-נ נתן לָ/תֵת la-tet
I-aleph אמר לֵ/אמֹר le-'emor
I-aleph אכל לֶ/אֱכֹל le-'ekhol

Qal Infinitive Construct — III-ה Roots

The final ה is replaced by וֹת (holem-waw + taw):

Root Bare IC + לְ Notes
ראה (see) רְאוֹת לִ/רְאוֹת Tsere often appears: לִרְאֹת
עשה (do) עֲשׂוֹת לַ/עֲשׂוֹת I-gutt. chateph under ע
היה (be) הֱיוֹת לִ/הְיוֹת Hateph-seghol under ה
הלך (go) לֶ/כֶת I-י replaces III-ה entirely; special form
שתה (drink) שְׁתוֹת לִ/שְׁתּוֹת
בנה (build) בְּנוֹת לִ/בְנוֹת
ידה (praise) הוֹדוֹת לְ/הוֹדוֹת Hiphil of ידה (more common)

Key marker: וֹת ending (holem-waw + taw) is the diagnostic for III-ה IC. It looks like a plural noun ending — do not confuse! The context (verbal behavior, following an object or subject) confirms IC.


Qal Infinitive Construct — Biconsonantal

Full long vowel is preserved in all biconsonantal IC forms:

Root Bare IC + לְ Notes
בוא (come) בֹּא לָ/בֹא Holem-waw; aleph quiesces
שוב (return) שׁוּב לָ/שׁוּב Full shureq
קום (arise) קוּם לָ/קוּם Full shureq
מות (die) מוּת לָ/מוּת Full shureq
שים (put) שִׂים לָ/שִׂים Full hireq-yod
ריב (contend) רִיב לָ/רִיב Full hireq-yod

Key marker: Biconsonantal IC retains the full long vowel of the root. The lamed prefix takes qamets (לָ–) before most biconsonantals.


Qal Infinitive Construct — I-י

I-י roots show contracted forms in the IC, often with a seghol-taw ending:

Root Bare IC + לְ Notes
הלך (go) לֶ/כֶת לֶ/כֶת No separate bare form common; the ל is fused
ישב (sit/dwell) שֶׁ/בֶת לָ/שֶׁ/בֶת Seghol + bet + taw
ידע (know) דַּ/עַת לָ/דַ/עַת Patach + ayin + taw
יצא (go out) צֵאת לָ/צֵאת Tsere + aleph + taw
ירד (go down) רֶ/דֶת לָ/רֶ/דֶת Seghol + dalet + taw
ירש (inherit) רֶ/שֶׁת לָ/רֶ/שֶׁת
ילד (give birth) לֶ/דֶת לָ/לֶ/דֶת

Key marker: I-י IC forms often end in ת (taw), giving them a distinctive noun-like appearance. לֶ/כֶת is the most common; the original yod/ה is absent.


Qal Infinitive Construct — I-נ

Nun assimilates in some roots; others are regular:

Root Bare IC + לְ Notes
נתן (give) תֵּת לָ/תֵת Both nuns drop; very short
נסע (set out) נְסֹ֣עַ לִ/נְסֹ֣עַ Nun retained (not assimilated in IC)
נגש (approach) גֶּשֶׁת לָ/גֶּשֶׁת Nun drops; seghol-taw
נשא (lift) שְׂאֵת לָ/שְׂאֵת Nun drops; tsere-taw
נפל (fall) נְפֹל לִ/נְפֹל Nun retained
נגד (tell) הַ/גִּיד לְ/הַ/גִּיד Hiphil more common for this root

Key marker: תֵּת (נתן = "to give") is one of the most striking IC forms — only two consonants visible. The I-נ root drops or assimilates the nun. Contrast with I-נ roots where nun is retained (נְסֹ֣עַ).


Qal Infinitive Construct — I-aleph

Root Bare IC + לְ Notes
אמר (say) אֱמֹר לֵ/אמֹר Hateph-seghol; quotative formula
אכל (eat) אֱכֹל לֶ/אֱכֹל Hateph-seghol under aleph
אהב (love) אֱהֹב לֶ/אֱהֹב
אסף (gather) אֱסֹף לֶ/אֱסֹף

Key marker: I-aleph IC has hateph-seghol under the aleph (composite shewa). The quotative לֵאמֹר (from אמר) is the most frequent IC form in the entire Hebrew Bible.
