Roots, the Seven Stems (Binyanim) and the Qal

Read this verse and count how many times you see the letters מ, ל, ך.

וְאֵלֶּה הַמְּלָכִים אֲשֶׁר מָלְכוּ בְּאֶרֶץ אֱדוֹם לִפְנֵי מְלָךְ־מֶלֶךְ לִבְנֵי יִשְׂרָאֵל׃

Genesis 36:31, Westminster Leningrad Codex

"These are the kings who reigned in the land of Edom before any king reigned over the Israelites." Four words share the same three consonants: הַמְּלָכִים "the kings," מָלְכוּ "they reigned," מְלָךְ "reigning" (an infinitive) and מֶלֶךְ "king." The consonants carry the idea "reign, king." The vowels and the extra letters around them say whether it is a person, an action, a time, a plural. That is the single most useful fact about Hebrew words, and this lesson is built on it.

The root

Almost every Hebrew verb, and most nouns and adjectives, can be traced to a root of three consonants (Gesenius, section 30). The root letters are also called radicals. A root by itself is not a word you can say; it is an abstraction, a set of letters with a shared meaning. Words are made by setting the root into a pattern: a fixed frame of vowels, sometimes with prefixes, suffixes or a doubled letter.

Grammars write a root with its letters separated, מ־ל־ך, or as plain consonants, מלך. Final forms are ignored: the root of מֶלֶךְ is מ ל כ, the same letter whether it is written כ in the middle of a word or ך at the end.

Lexicons such as Brown, Driver and Briggs are arranged by root. To find מַמְלָכָה "kingdom" in BDB, you look under מלך, not under מ־מ. That is why finding the root is the first skill of reading Hebrew, and why lesson 20 builds on this one.

One root, a family of words: מ־ל־ך

Notice מַלְכָּה and מַלְכִּי "my king" from lesson 9. Both show the older base malk- that hides inside מֶלֶךְ. Nouns of this type are called segolates, because the dictionary form usually has two segols, stressed on the first syllable: מֶלֶךְ, אֶרֶץ, דֶּרֶךְ. Lesson 6 met their construct and plural forms; the base comes back whenever a suffix is added.

Two more families

כ־ת־ב "write." כָּתַב [ka-TAV] "he wrote." וַיִּכְתֹּב [va-yikh-TOV] "and he wrote" (Exodus 24:4). כָּתוּב [ka-TUV] "written" (Psalm 40:8). מִכְתָּב [mikh-TAV] "writing, something written" (Exodus 32:16, where the tablets bear מִכְתַּב אֱלֹהִים "the writing of God"). יִכָּתֵבוּ [yi-ka-TE-vu] "they are written" (Psalm 139:16, of days written in God's book), a Niphal in pause. Later books add כְּתָב [ke-TAV] "writing, document" (BDB).

שׁ־מ־ר "keep, guard, watch." שָׁמַר [sha-MAR] "he kept" (Genesis 37:11). שֹׁמֵר [sho-MER] "keeper, guard" (Genesis 4:9). מִשְׁמָר [mish-MAR] "custody, guard" (Genesis 40:3, בְּמִשְׁמַר "in custody"). מִשְׁמֶרֶת [mish-ME-ret] "charge, duty" (Genesis 26:5, מִשְׁמַרְתִּי "my charge"). הִשָּׁמֶר [hi-sha-MER] "be careful, guard yourself" (Genesis 24:6), a Niphal imperative.

Patterns: the other half of the word

If the root is the meaning, the pattern is the grammar. Each pattern is a template with slots for the three radicals. Grammarians write the slots as C1 C2 C3, or with the letters of the old model verb פָּעַל "do, make": פ for the first radical, ע for the second, ל for the third. Medieval Jewish grammarians took this method over from Arabic grammar, and the names of the stems come from it, as you will see below.

The dagesh in כָּתַב and יִכְתֹּב is the dagesh lene of lesson 2: כ starts the word, and ת follows a silent shewa, so both are hard. In כָּתַב the final ב has no dagesh and is said v; in יִכְתֹּב the כ after the vowel i is soft, kh. So the same root letters sound different in different patterns: [ka-TAV], [yikh-TOV]. Train your eye to see the letter, not the sound.

Some noun patterns worth knowing

These are tendencies, not laws. They help you guess, and the lexicon confirms.

The seven stems (binyanim)

A Hebrew verb root can appear in up to seven main patterns, called stems or, using the Hebrew word, binyanim (singular בִּנְיָן [bin-YAN] "building"). Each stem has its own prefixes, vowels and doubling, and each changes the meaning of the root in a regular direction: passive, causative, reflexive and so on (Gesenius, section 39). No single root appears in all seven, and most appear in only one or two. But once you know the seven shapes you can recognize the stem of almost any verb, and that is half of parsing it.

The names

Six of the names are simply the 3rd masculine singular perfect of the old model verb פָּעַל in that stem: נִפְעַל Niphal, פִּעֵל Piel, פֻּעַל Pual, הִתְפַּעֵל Hithpael, הִפְעִיל Hiphil, הָפְעַל Hophal (Gesenius, section 39). The basic stem is called קַל Qal, "light," because it has no added letters or doubling. So the name tells you the shape: if you know that the Piel of פעל is פִּעֵל, you know the Piel of שׁבר is שִׁבֵּר.

The seven stems of קָטַל

Gesenius' Paradigm B sets out the strong verb in the root קָטַל "kill." The forms below are the 3rd masculine singular perfect and imperfect in each stem, as in Gesenius (sections 43 and 51 to 54). A real verse for each stem follows in the next table.

In הָקְטַל and יָקְטַל the qamets is a qamets hatuf, said o (lesson 2), because it stands in a closed unstressed syllable. Many Hophal forms have u instead: הֻגַּד [hu-GAD] "it was told" (Ruth 2:11).

Three columns: simple, doubled, causative

The seven stems fall into three groups, and seeing the grid makes them easy to hold.

Real verbs in each stem

One root, שׁ־ב־ר, shows how the first three stems relate. In Isaiah 14:5 the LORD שָׁבַר "broke" the staff of the wicked (Qal, simple action). In Exodus 22:9 an animal left in someone's care נִשְׁבַּר "was injured," literally "was broken" (Niphal, passive). In Exodus 9:25 the hail שִׁבֵּר "shattered" every tree of the field (Piel, many objects, thorough action).

וְלֹא־יָסַף שְׁמוּאֵל לִרְאוֹת אֶת־שָׁאוּל עַד־יוֹם מוֹתוֹ כִּי־הִתְאַבֵּל שְׁמוּאֵל אֶל־שָׁאוּל וַיהוָה נִחָם כִּי־הִמְלִיךְ אֶת־שָׁאוּל עַל־יִשְׂרָאֵל׃

1 Samuel 15:35, Westminster Leningrad Codex

"Samuel did not see Saul again until the day of his death, for Samuel mourned over Saul. And the LORD regretted that he had made Saul king over Israel." This one verse has four stems: יָסַף "he added, did again" (Qal), הִתְאַבֵּל "he mourned" (Hithpael), נִחָם "he regretted, was sorry" (Niphal), הִמְלִיךְ "he made king" (Hiphil). In הִתְאַבֵּל the prefix הִתְ is followed by the first radical א, and the dot in ב, the middle radical, is the doubling dagesh of the Hithpael.

What the stems mean, a little more exactly

• Qal. The plain meaning of the root. Both action verbs (שָׁמַר "keep," כָּתַב "write") and state verbs (כָּבֵד "be heavy," קָטֹן "be small") live here (Gesenius, section 43). Lesson 11 shows how state verbs look.
• Niphal. Usually the passive or reflexive of the Qal: נִשְׁבַּר "was broken," הִשָּׁמֶר "guard yourself." Some Niphal verbs simply have an active English meaning: נִלְחַם "fight," נִחָם "regret" (Gesenius, section 51).
• Piel. Gesenius and older grammars call it the intensive stem (Gesenius, section 52), and with some roots it does show many objects or forceful action, like שִׁבֵּר "smash." Very often, though, it turns a state into an action: Qal כָּבֵד "be heavy, be weighty," Piel כַּבֵּד "make weighty, honor" (כַּבֵּד אֶת־אָבִיךָ "Honor your father," Exodus 20:12); Qal "be holy," Piel וַיְקַדֵּשׁ "and he made holy" (Genesis 2:3). Some common verbs occur mainly in the Piel, such as דִּבֶּר "speak" (Genesis 21:1). Learn each Piel verb's meaning from the lexicon.
• Pual. The passive of the Piel, and with the Hophal one of the two least common stems. קֻבַּר "was buried."
• Hithpael. Reflexive ("do to oneself"), reciprocal ("to each other") or iterative ("go about doing"): וַיִּתְהַלֵּךְ "and he walked about, lived his life" (Genesis 5:22), וַיִּתְחַבֵּא "and he hid himself" (Genesis 3:8) (Gesenius, section 54).
• Hiphil. Causative of the Qal: מָלַךְ "reign," הִמְלִיךְ "make king"; כָּבֵד "be heavy," וַיַּכְבֵּד פַּרְעֹה אֶת־לִבּוֹ "and Pharaoh made his heart heavy" (Exodus 8:28) (Gesenius, section 53).
• Hophal. The passive of the Hiphil: הֻגַּד "it was told" (the Hiphil הִגִּיד means "tell").

Strong and weak roots

A strong root keeps all three letters, unchanged, in every form of every stem. שׁ־מ־ר, כ־ת־ב, מ־ל־ך, ז־כ־ר, פ־ק־ד are strong. Lessons 11 to 15 teach the verb with strong roots like these.

A weak root has at least one letter that behaves differently. Gutturals (א ה ח ע, and partly ר) cannot be doubled and prefer a-vowels and composite shewas. Nun at the start of a root often assimilates into the next letter. Yod and vav can turn into vowels or vanish. He at the end of a root is really a vowel letter. Grammarians name the classes by position, using the letters of פָּעַל or Roman numerals: a "Pe-Nun" or "I-Nun" verb has nun as its first radical. Lesson 16 teaches them all; here is the map.

Weak roots are not rare exceptions. Many of the most common verbs in the language are weak: אָמַר "say" (I-Aleph, as in וַיֹּאמֶר), הָיָה "be" (I-Guttural and III-He), עָשָׂה "do, make," נָתַן "give," הָלַךְ "go," בּוֹא "come." Learn the strong verb first because it shows every pattern with all its letters in place; then the weak verbs are the strong verb with predictable changes.

The Qal: the simple stem

The Qal is by far the most frequent stem. Most verb forms you read in Genesis, Ruth or Jonah are Qal, and it is the stem a lexicon lists first. Its dictionary form, by convention, is the 3rd masculine singular perfect, "he did": שָׁמַר is glossed "to keep" in English word lists, but the Hebrew form itself means "he kept." Hebrew has no infinitive-shaped dictionary form like English "to keep." When a lexicon says שָׁמַר "keep, guard," that is a convenience.

Why grammars use קָטַל

Gesenius sets out the strong verb with קָטַל "kill," as many grammars before and since have done (Gesenius, Paradigm B). It is a good model because none of its letters is a guttural, a weak letter or a begadkephat letter that would change between hard and soft, so every form shows the pattern cleanly. The verb itself is rare in the Hebrew Bible: in the books our lookup tool covers it occurs once, אִם־תִּקְטֹל אֱלוֹהַּ רָשָׁע "O that you would slay the wicked, O God" (Psalm 139:19). The ordinary Hebrew words for "kill" are הָרַג and the Hiphil of מוּת. So this course uses קָטַל as a pattern in the paradigms, and real verbs, above all שָׁמַר, כָּתַב, מָלַךְ, זָכַר "remember" and פָּקַד, in the readings.

Watch one thing when you move from קָטַל to כָּתַב or שָׁבַר: begadkephat letters change their sound with their position (כָּתַב [ka-TAV], יִכְתֹּב [yikh-TOV]). The pattern is the same; only the dagesh lene moves.

Action verbs and state verbs

Qal verbs come in two kinds. Fientive (action) verbs describe something done: שָׁמַר, כָּתַב, מָלַךְ. Their 3ms perfect has patah in the second syllable. Stative verbs describe a condition: כָּבֵד "be heavy" with tsere, קָטֹן "be small" with holem (Gesenius, section 43). Lesson 11 conjugates both kinds.

Finding the root, step by step

Hebrew uses a small, closed set of letters for prefixes and suffixes. Jewish grammar teachers have long taught them with two memory phrases. מֹשֶׁה וְכָלֵב "Moses and Caleb" holds the letters that can be prefixed to a word: מ (from), שׁ (which, the short relative of lesson 9), ה (the article or the question marker), ו (and), כ (like), ל (to), ב (in). אֵיתָן "Ethan" holds the four letters that begin the imperfect: א י ת נ, which you will meet in lesson 12. Add the suffix letters of lesson 9 and the verb endings of lesson 11, and you have nearly every letter that can be "outside" the root.

1. Take off the prefixes from the front: waw, article, prepositions. וּבְתוֹרָתוֹ becomes תוֹרָתוֹ.
2. Take off the suffixes from the end: pronoun suffixes, plural and feminine endings. תוֹרָתוֹ becomes תוֹר.
3. Take off pattern letters you recognize: the נ of the Niphal, the ה of the Hiphil, the הִתְ of the Hithpael, the מ of noun patterns like מִשְׁמָר, a vav or yod that is only a vowel letter.
4. What is left should be three consonants. If only two are left, one root letter has dropped or turned into a vowel: you have a weak root, and lesson 16 tells you where to look. תּוֹרָה is in fact a weak root, י־ר־ה "teach, point out," whose first and last letters both hide (BDB lists it under ירה).

That last example is a warning not to stop too early. The vav of תּוֹרָה is a vowel letter for o, and the ת is a prefix of the noun pattern. The root letters are hiding in plain sight. Reading the vowels as well as the consonants is what lets you see that.

Roots with the same letters

Sometimes two or more unrelated roots happen to have the same three letters. Lexicons number them. BDB has four separate roots spelled ענה: I "answer," II "be occupied with," III "be bowed down, afflicted," and IV "sing." The Open Scriptures morphology marks such splits with letters after the Strong number, which is why the lookup tool shows codes like "5674 a" and "5674 b" for two meanings of עבר. When a gloss does not fit the sentence, check whether you are in the wrong root.

Not every word has a three-letter root

Some of the oldest nouns in the language, such as אָב "father," אֵם "mother" and יָד "hand," have only two consonants and are best learned as words, not derived from a verb. Gesenius discusses the old question whether many three-letter roots grew from shorter ones (Gesenius, section 30). A few nouns have four consonants: צְפַרְדְּעִים "frogs" (Exodus 7:28) is one. Names from other languages, such as פַּרְעֹה "Pharaoh," do not follow Hebrew roots at all. These are a small minority. For verbs, three-letter roots are the rule.

Parsing: the words you need

To parse a verb is to name everything its form tells you. A full parse of a Hebrew verb has six parts.

So שָׁמַרְתִּי is "Qal perfect 1st common singular of שׁמר: I kept" (1 Samuel 25:21). Add any prefixes and suffixes: וַיִּכְתֹּב is "Qal waw-consecutive imperfect 3rd masculine singular of כתב: and he wrote" (Exodus 24:4). יִמְלֹךְ is "Qal imperfect 3ms of מלך: he will reign" (Exodus 15:18).

On the word "conjugation": in Hebrew grammar it names the form class (perfect, imperfect and so on), not the whole set of forms as in Latin or Greek. Some books call the perfect and imperfect "tenses," others "aspects," and many modern grammars call them by their 3ms shapes, qatal and yiqtol. This course says perfect and imperfect, like Gesenius, and explains what they mean in lessons 11 and 12.

Reading a morphology code

The lookup tool behind this course, and many online Hebrew Bibles, label every word with a code from the Open Scriptures Hebrew Bible. Once you know the parsing words, the codes read themselves.

Examples from the tool: שָׁמַר HVqp3ms; וַיִּשְׁמֹר HC/Vqw3ms (the C before the slash is the conjunction waw); הִמְלִיךְ HVhp3ms; נִשְׁבַּר HVNp3ms; הִתְאַבֵּל HVtp3ms; שֹׁמֵר HVqrmsa (participle, masculine singular, a for absolute state). Notice that the same lower-case p means Piel in the stem slot and perfect in the conjugation slot: HVpp3ms is a Piel perfect, like שִׁבֵּר.
