Arabic vs Hebrew: Similarities and Differences

If you've ever studied Arabic and stumbled upon Hebrew — or vice versa — you may have felt that eerie sense of familiarity. Words that almost match, sounds that echo each other, a script that flows in the same direction. That's no coincidence. Arabic and Hebrew are sister languages, both members of the ancient Semitic language family, and their kinship runs surprisingly deep.

Whether you're an Arabic learner curious about Hebrew, a linguist comparing Semitic languages, or simply someone fascinated by the history of language, this guide will walk you through the most important similarities and differences between Arabic and Hebrew — covering scripts, sounds, grammar, vocabulary, and more.

What Are Semitic Languages?

The Semitic language family is one of the oldest and most historically significant language groups in the world. It includes languages spoken across the Middle East and North Africa, both ancient and modern:

• Arabic (over 400 million speakers)
• Hebrew (~9 million speakers)
• Aramaic (historically significant; still spoken by small communities)
• Amharic (Ethiopia's official language)
• Tigrinya (spoken in Eritrea and Ethiopia)
• Maltese (spoken in Malta, heavily influenced by Arabic)

Arabic and Hebrew both belong to the Central Semitic branch, making them closer relatives than, say, Arabic and Amharic. Their shared ancestor is Proto-Semitic, a reconstructed ancient language spoken thousands of years ago.

Understanding this shared ancestry is key to appreciating both the deep similarities and the fascinating divergences between the two languages.

Writing Direction and Script

One of the first things learners notice is that both Arabic and Hebrew are written from right to left. This stands in sharp contrast to most European languages and is often the first hurdle for English speakers approaching either language.

Arabic Script

Arabic uses its own unique alphabet of 28 letters, all of which are consonants or long vowels. Short vowels are typically indicated by diacritical marks (harakat) placed above or below letters, but in most everyday texts, these are omitted — readers are expected to infer them from context.

A distinctive feature of Arabic script is that letters are cursive by nature: most letters connect to the letter that follows them within a word. Each letter can take up to four different forms depending on its position — isolated, initial, medial, or final. You can explore how this works in detail in our guide to Arabic Letter Forms Explained: Isolated, Initial, Medial, and Final.

Hebrew Script

Hebrew uses the Hebrew alphabet (Aleph-Bet), consisting of 22 letters, also all consonants. Like Arabic, short vowels are represented by an optional diacritical system called nikud (vowel points), which is mainly used in children's books, religious texts, and poetry. Everyday modern Hebrew omits these vowel marks entirely.

Unlike Arabic, most Hebrew letters do not connect to the following letter — they are written as distinct, block characters (though a cursive Hebrew script exists for handwriting).

Side-by-Side Comparison

Feature	Arabic	Hebrew
Direction	Right to left	Right to left
Number of letters	28	22
Cursive (print)	Yes	No (block form)
Vowel system	Harakat (optional)	Nikud (optional)
Letter position forms	4 forms per letter	Generally 1–2 forms

Sounds and Phonology

Both Arabic and Hebrew share a number of guttural and emphatic consonants that are uncommon in European languages, which is one reason both can feel challenging to English speakers at first.

Shared Sounds

Here are some sounds found in both languages:

• ʿAyin (ع / ע) — a voiced pharyngeal fricative; a deep, throaty sound
• Alef (ء / א) — a glottal stop
• Ḥet (ح / ח) — a voiceless pharyngeal fricative; a breathy "h" sound
• Shin (ش / ש) — the "sh" sound
• Kaf (ك / כ) — the "k" sound

Sounds Unique to Arabic

Arabic has several sounds with no Hebrew equivalent, including:

• Ḍad (ض) — an emphatic "d"; Arabic is sometimes called Lughat al-Ḍad (the language of Ḍad)
• Ẓa (ظ) — an emphatic "th" or "z"
• Ghain (غ) — a voiced uvular fricative (similar to a French "r")
• Tha (ث) — the "th" sound (as in "think")

Sounds Unique to Hebrew

Modern Hebrew has simplified its consonant inventory compared to ancient Hebrew and no longer distinguishes some sounds that Arabic preserves. For example, modern Hebrew has largely merged sounds like dalet and zayin into simpler categories.

Interestingly, Classical Arabic preserves more sounds from Proto-Semitic than Modern Hebrew does. This makes Arabic phonology feel richer and more complex to learners approaching it for the first time.

The Root System: A Shared Foundation

Perhaps the single most important structural similarity between Arabic and Hebrew is the triconsonantal root system — a feature that makes Semitic languages unlike almost any other language family in the world.

In both languages, the vast majority of words are built from a root of three consonants (sometimes four), which carries a core meaning. Different words are formed by inserting different vowel patterns and affixes around this root.

Arabic Example: K-T-B (كتب)

Word	Meaning
كَتَبَ (kataba)	He wrote
كِتَاب (kitāb)	Book
كَاتِب (kātib)	Writer
مَكْتَب (maktab)	Office / desk
مَكْتُوب (maktūb)	Written / letter

Hebrew Equivalent: K-T-V (כתב)

Word	Meaning
כָּתַב (katav)	He wrote
כְּתָב (ktav)	Script / writing
כּוֹתֵב (kotev)	Writer
מִכְתָּב (miktav)	Letter (correspondence)

Notice how the root K-T-B/V is virtually identical across both languages, and the words derived from it carry remarkably similar meanings. This is not a coincidence — it's a direct inheritance from their shared Proto-Semitic ancestor.

This root system is one of the most elegant aspects of Arabic. To learn more about how it works, read our deep-dive article: Arabic Root System Explained: How 3-Letter Roots Build Words.

Shared Vocabulary

Because of their common ancestry, Arabic and Hebrew share a significant amount of cognate vocabulary — words that sound similar and share meaning. Here are some fascinating examples:

English	Arabic	Hebrew
Peace	سَلَام (salām)	שָׁלוֹם (shalom)
King	مَلِك (malik)	מֶלֶךְ (melech)
House	بَيْت (bayt)	בַּיִת (bayit)
Book	كِتَاب (kitāb)	כְּתָב (ktav)
Heart	قَلْب (qalb)	לֵב (lev)
Name	اِسْم (ism)	שֵׁם (shem)
Water	مَاء (mā')	מַיִם (mayim)
Son	اِبْن (ibn)	בֵּן (ben)
God	اَللَّه (Allāh) / إِلَه (ilāh)	אֵל (El) / אֱלֹהִים (Elohim)

The word for "peace" is perhaps the most famous: Arabic salām (سَلَام) and Hebrew shalom (שָׁלוֹם) are clearly related — and both are used as greetings. The Arabic greeting As-salāmu ʿalaykum (Peace be upon you) and the Hebrew Shalom aleichem are essentially the same phrase in two sister languages.

Grammar: Similarities and Differences

Similarities

Both Arabic and Hebrew share several core grammatical structures:

1. Grammatical Gender Both languages assign masculine or feminine gender to nouns. Generally, feminine nouns end in a ta marbuta (ة) in Arabic or a tav (ת) / heh (ה) in Hebrew.

2. Dual Number Both languages have a dual form for nouns and some verb conjugations — a special grammatical category for exactly two of something. English lost this feature long ago.

3. Verb-Subject-Object (VSO) Order Classically, both languages favor a verb-first sentence structure, though Modern Hebrew has largely shifted to Subject-Verb-Object (SVO) order — more like English.

4. Broken Plurals Both languages use internal vowel changes to form irregular ("broken") plurals, rather than simply adding a suffix.

• Arabic: كِتَاب (kitāb, book) → كُتُب (kutub, books)
• Hebrew: סֵפֶר (sefer, book) → סְפָרִים (sfarim, books)

5. Definite Articles Both languages use a prefixed definite article:

• Arabic: الـ (al-) → e.g., البيت (al-bayt, the house)
• Hebrew: הַ (ha-) → e.g., הַבַּיִת (ha-bayit, the house)

Differences

Verb Conjugation Complexity Arabic verb conjugation is generally considered more complex than Hebrew, with more tenses, moods, and forms. Classical Arabic in particular has an elaborate system of verb patterns (أوزان, awzān) that learners must master.

Case System Classical and Modern Standard Arabic retains a three-case system (nominative, accusative, genitive) for nouns. Modern Hebrew has largely abandoned grammatical case.

Formality Levels Arabic has a significant split between Modern Standard Arabic (MSA) — used in formal writing and media — and the many spoken dialects, which can vary dramatically. This is called diglossia. Learn more about this in our article on Arabic Dialects Explained. Hebrew, while it has informal registers, does not have as dramatic a divide between written and spoken forms.

Difficulty for English Speakers

Both Arabic and Hebrew are classified by the U.S. Foreign Service Institute (FSI) as Category IV languages — the most difficult category for English speakers — requiring approximately 2,200 class hours to achieve professional proficiency.

That said, there are some nuances:

• Hebrew is generally considered slightly easier for beginners because its consonant inventory is smaller, Modern Hebrew grammar has been simplified, and its script (block letters) may be easier to learn initially.
• Arabic offers the advantage that once you learn MSA, you have access to written content across the entire Arab world, covering 22+ countries. Its script, while initially daunting, has a beautiful logic to it.

Should You Learn Both?

Knowing one Semitic language genuinely does help with the other. Many learners report that their second Semitic language feels significantly more accessible than the first, because the root system, grammar logic, and even script direction are already familiar.

Cultural and Historical Connections

Beyond linguistics, Arabic and Hebrew are deeply intertwined in history and culture.

Shared Religious Texts Both languages have been vehicles for major world religions. Hebrew is the language of the Torah and Jewish scriptures. Arabic is the language of the Quran. Both are considered sacred languages by billions of people worldwide, and both have been preserved in part due to the religious importance of their classical forms.

Medieval Intellectual Exchange During the Islamic Golden Age (8th–13th centuries), Jewish scholars living in Arab lands became deeply fluent in Arabic. Many wrote in Judeo-Arabic — a dialect of Arabic written in Hebrew letters. The great Jewish philosopher Maimonides (Rambam) wrote his famous Guide for the Perplexed in Judeo-Arabic.

Loanwords Arabic has borrowed from Hebrew (especially in religious contexts), and Hebrew has borrowed extensively from Arabic over centuries of contact. Modern Hebrew also borrowed from Arabic dialects spoken by Jewish immigrants from Arab countries.

The Names Connection Many names used in both cultures share the same Semitic roots. Names like Ibrahim/Avraham (Abraham), Musa/Moshe (Moses), Maryam/Miriam, and Dawud/David are cognates across both languages — reflecting their shared Abrahamic heritage.
