Short Vowels in Arabic Orthography

Introduction

Arabic is a consonantal language whose script was originally written without any indication of vowels. Over time, diacritical markscalled tashklwere introduced to represent short vowels, assist learners, and aid in the correct recitation of the Quran. This page explains the three short vowels, their symbols, pronunciation, and practical rules for their use.

The Three Short Vowels

In Arabic there are three short vowel sounds, each represented by a single diacritic placed above or below a consonant letter:

• Fatha () a short a as in cat.
• Kasra () a short i as in machine.
• amma () a short u as in put.

These marks are never written on their own; they always accompany a consonant (or the letter alif when it functions as a seat for the vowel).

How the Marks Are Placed

Position relative to the base letter

• Fatha sits above the letter.
• Kasra sits below the letter.
• amma sits above the letter, slightly to the right of fatha.

Interaction with the shadda

If a consonant carries a doubling sign (shadda, ), the short vowel is written after the shadda:

Sukn () and the absence of a vowel

When a consonant is not followed by a short vowel, a sukn is placed to indicate silence. The presence of a sukn often determines which short vowel will appear on the next letter.

Rules Governing Short Vowel Usage

1. Wordfinal vowels

In most modern written Arabic, short vowels are omitted at the end of words, especially in newspapers and books for native readers. In educational texts or Quranic script they are retained.

2. Definite article al ()

The al prefix is normally written with a fatha on the alif () and a sukn on the lam when the following letter is a sun letter. In the case of a sun letter, the lam is assimilated and the short vowel moves to the doubled consonant:

3. Declension and case endings

In Classical Arabic, nouns and adjectives receive case endings marked by short vowels:

• un () for the nominative.
• an () for the accusative.
• in () for the genitive.

These are written as a combination of a short vowel plus a tanwn sign (double diacritic).

4. Verbal morphology

Verb patterns () are largely defined by the placement of short vowels. For example, the perfect thirdperson masculine singular pattern is faala () fatha, then a sukoon on the second radical, then fatha on the third.

5. NonArab learners

For students of Arabic, short vowels are crucial for correct pronunciation, especially because many words differ only by vowel quality (e.g., kabara he grew vs. kubira he was magnified).

Short Vowels in Digital Text

Modern keyboards and word processors support Arabic diacritics. When typing, the vowel symbols are entered after the base consonant. Most fonts render them clearly, but some lowresolution displays may make them hard to read.

Web developers should ensure that:

• HTML documents declare charset="UTF-8" to encode diacritics correctly.
• CSS sets a font that includes Arabic diacritics, such as Amiri or Scheherazade.
• Lineheight is sufficient (1.4) so the diacritics do not overlap adjacent lines.

Example of proper markup:

<p> </p>

Summary

Short vowelsfatha, kasra, and ammaare small yet essential symbols that give Arabic its phonetic clarity. They are positioned relative to the base letter, interact with other diacritics such as shadda and sukn, and follow consistent orthographic rules that influence morphology, syntax, and pronunciation. While native texts often omit them for speed, learners and religious texts retain them to preserve meaning and recitation accuracy.
