The ezafe (izafe) is a short unstressed vowel, -e, that links a noun to a following adjective, possessor, or other modifier in Persian. It usually goes unwritten in everyday script, so ketab-e bozorg (the big book) looks like two plain words but is pronounced with the linking -e between them.

When is it -e and when -ye?

After a word ending in a consonant the ezafe is just -e, often shown by a kasra. After a word ending in a vowel ا و ه ی it becomes -ye to avoid a vowel clash, written with a ye or a hamza over a final he. The tool checks the last grapheme of the first word to choose the form.

Why does it skip some gaps?

Ezafe links a head noun to its modifier, not arbitrary adjacent words. The tool skips gaps where the first word is a preposition or conjunction (az, be, va, ke) or where the second word starts a new clause or is the copula, because no ezafe links across those boundaries.

Is this a perfect parser?

No. True ezafe placement requires full syntactic analysis, which Persian's unwritten vowels make ambiguous. This tool uses a practical heuristic over content-word boundaries and a stop-word list, so it is a strong study aid but you should confirm each flag against the intended meaning.

Does my text stay private?

Yes. Detection runs entirely in your browser using grapheme checks and a built-in stop-word list. Nothing you enter is uploaded, logged, or stored on any server.

Finding the invisible linker in Persian

Persian writes most short vowels invisibly, and the most important of them is the ezafe — the -e that ties a noun to whatever describes or possesses it. Beginners constantly mis-read phrases because the linker is not on the page. This tool scans your text and flags where the ezafe most likely belongs, and in which form.

How it works

The ezafe links a head noun to a following modifier, so the tool examines each gap between adjacent words and decides whether a link is plausible:

کتاب  بزرگ  من   ->  ketab -e bozorg -e man
"book" "big"  "my"      book-EZAFE big-EZAFE my

A gap is flagged unless the first word is a known preposition or conjunction, or the second word begins a new clause (for example va, ke, the copula ast, or a preposition). For each flagged gap the form is chosen by the first word’s final letter: vowel-final words ا و ه ی take -ye, everything else takes -e.

Tips and notes

The default phrase کتاب بزرگ من (“my big book”) shows two ezafe links in a row, which is normal — a chain of modifiers each gets its own linker. Because Persian leaves vowels unwritten, no purely lexical tool can be perfect; treat the flags as a learning aid and confirm them against meaning. For other invisible-pronunciation rules, see the Arabic sun/moon letter checker and the Hindi schwa deletion helper.
