Prefixes in Hebrew

Further information on Hebrew grammar: Hebrew grammar and Hebrew verb conjugation

There are several prefixes in the Hebrew language which are appended to regular words to introduce a new meaning. In Hebrew, the letters that form those prefixes are called "formative letters" (Hebrew: אוֹתִיּוֹת הַשִּׁמּוּשׁ, Otiyot HaShimush). Eleven of the twenty-two letters of the Hebrew alphabet are considered Otiyot HaShimush. These letters are Aleph (א), Bet (ב), He (ה), Vav (ו), Yud (י), Kaf (כ), Lamed (ל), Mem (מ), Nun (נ), Shin (ש), and Tav (ת). A mnemonic to remember these letters is איתן משה וכלב (Eitan, Moshe, v'Kalev), which translates to "Ethan, Moses, and Caleb."

Prefixes in Hebrew serve multiple purposes. A prefix can serve as a conjunction, preposition, definite article, or interrogative. Prefixes are also used when conjugating verbs in the future tense and for various other purposes.

Conjunctions

Prefix	Meaning	Comments	Examples
ו‎ (Vav)	and	Vav-conjunctive (cf. Vav-consecutive) can make the "v" sound (/v/) or the "u" sound (/u/). If it is used with other prefixes, this is always the first prefix. In front of ב, פ and מ waw (ו) is read as "u" sound.	וְהוּא‎ v'hu[1] (and he) וּבַיוֹם‎ uvayom[2] (and on the day)

Inseparable prepositions

Prefix	Meaning	Comments	Examples
ל‎ (Lamed)	to, for, onto	The Inseparable Prepositions are pointed: Normally with Sheva. Before a Sheva they take Chirik. Before יְ‎ they take Chirik, but the Sheva under the י‎ falls away. Before a T'nua Chatufa they assume the corresponding short vowel. Before אֶלֹהִים‎ they take Tzere and the T'nua Chatufa under the א‎ disappears.	לְמֶלֶךְ‎ l'melekh (to a king) לִמְלָכִים‎ lim'lokhim (to kings) לִיהוּדָה‎ lihudah (to Judah) לַאֲרִי‎ la'ari (to the lion) לֵאלֹהִים‎ lelohim (to God)
ב‎ (Bet)	in, on, with, by		בְּמֶלֶךְ‎ b'melekh (in a king) בִּמְלָכִים‎ bim'lokhim (in kings) בִּיהוּדָה‎ bihudah (in Judah) בַּאֲרִי‎ ba'ari (in a lion) בֵּאלֹהִים‎ belohim (in God)
כ‎ (Kaf)	as, like		כְּמֶלֶךְ‎ k'melekh (as a king) כִּמְלָכִים‎ kim'lokhim (as kings) כִּיהוּדָה‎ kihudah (Like Judah) כַּאֲרִי‎ ka'ari (Like a lion) כֵּאלֹהִים‎ kelohim (Like Gods)

Other prepositions

Prefix	Meaning	Comments	Examples
מ‎ (Mem)	from/of/out of/than	Before ordinary letters (excluding the gutturals and ר‎) it is מִ‎ followed by a Dagesh Chazak. Before gutturals and ר‎ it is מֵ‎. Before the definite article (ה‎) it is מֵ‎ as in 2, and the article remains intact; or it becomes מִן‎ plus ה‎.	מִמֶּלֶךְ‎ mimelekh (from a king) מֵאָדָם‎ me'adam (from a man) מֵהַמֶּלֶךְ‎ mehamelekh (from the king), or מִן הַמֶּלֶךְ‎ min hamelekh

Definite article

Prefix	Meaning	Comments	Examples
ה‎ (He)	the	Before ordinary letters (i.e. excluding gutturals and ר‎) it is הַ‎ followed by a Dagesh Chazak.	הַמֶּלֶךְ‎ hamelekh (the king)
		Before the weaker gutturals א‎ and ע‎, as well as ר‎, it is הָ‎.	הָאוֹר‎ ha'or (the light) הָעַיִן‎ ha'ayin (the eye) הָרֹאשׁ‎ harosh (the head)
		Before the harsh gutturals ה‎ and ח‎ it is הַ‎.	הַהוֹד‎ hahod (the glory) הַחֹשֶׁךְ‎ hachoshekh (the darkness)
		Before an unaccented הָ‎ and עָ‎ and always before חָ‎ it is הֶ‎.	הֶהָרִים‎ heharim (the mountains) הֶעָפָר‎ he'afar (the dust) הֶחָכָם‎ hechakham (the wise)
		Before an accented הָ‎ and עָ‎ it is הָ‎.	הָהָר‎ hahar (the mountain) הָעָז‎ ha'az (the strong)
		When used with the Bet, Kaf or Lamed prepositional prefix it is omitted; instead the vowel on the preposition is changed. If He is used with other prefixes, the He is always the last prefix before the root.	וּבַיוֹם‎ uvayom[3] (and on the day: note that the ve (on) combines with the ha (the) to become va (on the)).

Interrogative

Prefix	Meaning	Comments	Examples
ה‎ (He)	...?	Used to indicate a question. Can usually be distinguished from the definite article because it is vowelized with a chataf patach	הֲבֵן יַקִּיר לִי?‎ haven yaqir li?[4] (Is he my most precious son?)

Non Otiyot HaShimush

European languages had a large stock of prefixes for technical terminology mostly taken from Greek and Latin. While Hebrew traditionally did not use this kind of prefixes, professionals in the Yishuv who started to teach and work in Hebrew were used to this terminology, and incorporated most of these prefixes into Hebrew. Meanwhile, people working on revitalising the language coined some Hebrew parallels, so today those foreign and Hebrew prefixes are used interchangeably.
