Prepositionsבְּ · לְ · כְּ · מִן — the small words that wire the sentence

Hebrew, like every Semitic language, leans heavily on a small inventory of prepositions to express the relations between nouns, verbs, and ideas — relations that English expresses with whole batteries of prepositions ("in, into, on, upon, with, by, by means of, at, near, beside, before, after, above, beneath, through, toward, away from…"). A single Hebrew preposition often covers two or three English ones at once. בְּ, for example, can mean "in," "at," "on," "with," or "by means of," depending on context. לְ can mean "to," "for," "belonging to," or simply mark an indirect object. Learning to read the prepositions is less about memorising one-to-one English glosses and more about absorbing the range each one covers.

Three of the most common Hebrew prepositions — בְּ, לְ, and כְּ — are so short that they never stand alone. They are written as single consonants prefixed to the following word, with their own vowel. Grammarians call them the inseparable prepositions. Most of the work of this lesson is learning what vowel each one takes in each environment.

A fourth preposition, מִן "from," is an "independent" word but behaves a great deal like a prefix in practice — its nun typically assimilates into the following consonant, leaving מִ plus a doubling dagesh. The remaining major prepositions (עַל, אֶל, עִם, and so on) are independent words connected to their object by maqqef (the small horizontal stroke ־), and they keep their full form.

In the ordinary case — an indefinite noun that begins with a single consonant followed by a full vowel — the inseparable preposition takes a vocal shewa beneath it. This is the form you will see most often.

Hebrew rejects two consecutive vocal shewas at the start of a syllable. So when the noun itself begins with a shewa, the preposition can't keep its default shewa. Instead, the preposition's vowel shifts to hireq (short i), and the noun's initial shewa stays put.

You learned in Lesson 7 that the definite article הַ "the" is itself a prefix — a he with patach and a doubling dagesh in the following consonant. When one of the inseparable prepositions attaches to a noun that already has the article, something striking happens: the he of the article drops out altogether, but its vowel (and its dagesh) remain in place under the preposition.

The result is that the preposition appears to "absorb" the article. You see one letter (the preposition), but it is pointed with the article's vowel — usually patach — and the following consonant still carries the article's dagesh forte. The word is still definite; only the he is missing.

The four gutturals (א ה ח ע) refuse to take a regular vocal shewa, as you learned in Lesson 2. When an inseparable preposition is followed by a guttural carrying a hateph-vowel (compound shewa), the preposition takes the corresponding short vowel — that is, the preposition's vowel "echoes" the hateph beneath the guttural.

The fourth very common preposition is מִן "from / out of / away from / because of." Unlike בְּ, לְ, כְּ, it is technically a two-letter independent word — but it nearly always loses its final nun in connected speech, and the lost nun is recorded in the writing as a dagesh forte in the next consonant. The remaining form is מִ + dagesh.

When the next letter is a guttural (which cannot take a dagesh), the nun cannot assimilate — and in compensation the hireq of מִ lengthens to tsere, giving the form מֵ.

Strictly speaking אֵת is not a preposition — it is a function word that marks the direct object of a verb when that object is definite. English has nothing like it. We mark direct objects only by word order ("the king killed the lion" — "the lion" is the object because it follows the verb). Hebrew marks direct objects explicitly when they are definite, by placing אֵת in front of them.

It has no English equivalent and you should generally leave it untranslated. Its only function is grammatical: "the next word is the direct object, and it is definite." Before a definite noun it most commonly appears in the form אֶת־ with maqqef.

Hebrew loves to combine a short preposition with a noun (often a body-part noun) to express a more specific spatial or relational idea. These compound prepositions are written as two words (sometimes joined by maqqef) and translated as a single unit in English.
