Tashkeel, also called harakat, are the small diacritical marks written above and below Arabic letters to indicate short vowels, gemination (shadda), and the absence of a vowel (sukun). Most everyday Arabic omits them and relies on the reader to supply vowels from context.

Why does diacritic density matter?

Fully vocalised text is far easier for learners and is required for the Quran, children's books, and ambiguous words. Native adult readers usually read unvocalised text fluently, so density is a strong signal of the intended audience.

Which marks count as diacritics here?

The meter counts fatha, kasra, damma, their tanwin forms, sukun, shadda, the superscript alef, and related Unicode marks in the U+064B–U+0652 and related ranges. A word counts as vocalised if it carries at least one such mark.

Does it change my text?

No. The tool only reads and counts marks; it never adds, removes, or rewrites diacritics. Everything runs locally in your browser and nothing is uploaded.

The Arabic Diacritic Density Meter reports what share of words in a passage carry tashkeel (harakat). Because fully vocalised Arabic is mainly used for learners, religious texts, and disambiguation, the density figure is a quick signal of how a text is intended to be read.

How it works

The text is split into words. For each word the tool checks whether it contains any Arabic diacritic codepoint:

fatha   ◌َ  U+064E     kasra   ◌ِ  U+0650
damma   ◌ُ  U+064F     sukun   ◌ْ  U+0652
shadda  ◌ّ  U+0651     tanwin  ◌ً ◌ٍ ◌ٌ  U+064B–U+064D
plus superscript alef U+0670 and related marks

A word is classed as vocalised if it carries at least one of these marks, and the density is the count of vocalised words divided by the total word count. The tool also reports the raw diacritic-mark count and average marks per word.

Tips and notes

A density near 100% indicates fully pointed text, as in the Quran or graded learner material. A density near 0% is normal for newspapers, novels, and most native adult reading, where vowels are inferred from context. Partial density often marks selective pointing, where only ambiguous or unusual words are vocalised. Use the figure together with the per-word average: a low word percentage but high mark count can mean a few heavily pointed words rather than evenly distributed marks.
