Urdu and Arabic often sound close to many speakers—especially in religious or formal settings. Linguistically, though, they belong to different families. Here’s a clean, referenced overview of where they truly overlap (and where they don’t), how much Urdu draws from Arabic, and which languages are actually closest to Arabic.
1) Language families (so we don’t mix categories)
- Arabic is a Semitic language (within the Afro-Asiatic family), alongside Hebrew and Aramaic. Wikipedia
- Urdu is Indo-Aryan (Indo-European), closely related to Hindi; the two share a grammatical base but differ in script and much of their higher-register vocabulary. Encyclopedia Britannica
Takeaway: Urdu isn’t genetically related to Arabic—but centuries of contact (religion, scholarship, courts) created large lexical overlap.
2) Script & writing tradition: the visible similarity
Urdu uses a Perso-Arabic writing system in the Nasta?l?q style (right-to-left, calligraphic), which is why printed Urdu looks Arabic-like to the eye. Encyclopedia Britannica+1
3) How much Urdu comes from Arabic?
There isn’t a single “official” percentage—because estimates depend on which corpus/register you measure (newspapers vs. poetry vs. everyday speech).
Helpful anchors:
- A widely cited summary: Urdu’s grammatical core is Indo-Aryan; ~99% of verbs are from Sanskrit/Prakrit, while much of the higher vocabulary is borrowed from Persian and (to a lesser extent) Arabic, often via Persian. Dawn
- Encyclopedic overviews note Persian (and, through Persian, Arabic) supply roughly 25–30% of the general Urdu lexicon, while some formal texts can be heavily “Perso-Arabic” (up to ~70% in certain registers). Wikipedia
- Corpus studies and morpho-loanword research further document the systematic integration of Persian/Arabic vocabulary into Urdu. ResearchGate+1
A careful summary:
For general Urdu, expect a few tenths of the vocabulary to be of Persian/Arabic origin, with Arabic typically entering via Persian. In religious, legal, and literary high registers, Perso-Arabic items can dominate the visible lexicon—even though the grammar remains Indo-Aryan. Wikipedia+1
4) Concrete overlap you’ll hear every day
Shared Arabic-origin items are especially common in religion, scholarship, governance, and abstract concepts:
- kit?b (book), ?ilm (knowledge), ?ad?lat (justice), duny? (world), ?ib?dat (worship), qiy?mat (resurrection), hukm (order/command), shukr (gratitude), ra?mat (mercy) — all used natively in Urdu speech/writing. (General lexical pathways summarized in the sources above.) Wikipedia
5) So… which language is closest to Arabic?
If we mean genetic closeness (i.e., family tree), the closest languages to Arabic are other Semitic languages (Hebrew, Aramaic, Amharic/Tigrinya, etc.). Wikipedia
A special case is Maltese, which developed from a variety of Arabic (Siculo-/North-African Arabic) and is the only Semitic language written in Latin script—making it linguistically the closest large national language to Arabic in Europe. Encyclopedia Britannica+1
Where does Urdu fit?
Urdu is not a Semitic language, so it’s not “closest” to Arabic genetically. But among major South-Asian languages, Urdu sits near the top for practical proximity because of:
- centuries of Arabic (often via Persian) loanwords in religion, law, and literature, and
- use of a Perso-Arabic script (Nasta?l?q). Wikipedia+1
6) Key similarities and differences — at a glance
| Feature | Urdu | Arabic |
|---|---|---|
| Language family | Indo-Aryan (Indo-European) | Semitic (Afro-Asiatic) |
| Script | Perso-Arabic, Nasta?l?q | Arabic script (various hands) |
| Grammar core | Indo-Aryan; verbs overwhelmingly Sanskrit/Prakrit | Semitic root-pattern morphology |
| Lexicon | Significant Persian + Arabic layer (size varies by register) | Native Semitic; vast internal derivation |
| Everyday mutual intelligibility | No (except shared loanwords/phrases) | High within Arabic dialects; with Maltese: partial/asymmetric |

Bottom line
- Urdu and Arabic are different families, but look and sound connected because Urdu writes in a Perso-Arabic script and has large layers of Persian/Arabic vocabulary in many registers. Encyclopedia Britannica+1
- In broad, cautious terms, a few tenths of Urdu’s vocabulary is of Persian/Arabic origin overall, with Arabic typically entering through Persian—and some formal/religious Urdu can be majority Perso-Arabic by word-count. Wikipedia
- Closest to Arabic genetically are Semitic languages (e.g., Hebrew, Aramaic); Maltese is a living European language descended from Arabic. Urdu’s “closeness” is cultural-lexical, not genealogical. Wikipedia+2Encyclopedia Britannica+2
