Qalqalah · The Bounce

Five strong letters get a little bounce — a clear echo — whenever they carry a sukoon, so they ring out instead of getting stuck.

What is qalqalah?

Qalqalah (القَلْقَلَة) means a bounce or echo. Five letters are so “strong” — the sound is fully stopped and voiced — that when they carry a sukoon they would get stuck silent. So we release them with a quick bounce, letting the letter ring clearly without adding any vowel.

Why these five?

The qalqalah letters share two traits: shiddah (the sound stops completely) and jahr (the voice is full, no breath escapes). With a sukoon, neither breath nor voice can release them — so a tiny bounce sets them free.

It is a vowel-less echo: not a fat-ha, kasra, or damma — just a clean bounce.

Qalqalah only happens when one of these letters has a sukoon — never when it carries a vowel.

The five letters

Tap a letter to feel the bounce

Each letter is shown with two examples: a lighter bounce when it sits in the middle of a word, and a stronger bounce when you stop on it at the end.

قُطْبُ جَدٍّ — ق ط ب ج د

Two degrees

A lighter bounce & a stronger one

How big the bounce is depends on where the sukoon letter sits. Tap each level to open it.

DO ✓
أَحَدْ

Clean bounce — “aḥad” with a quick echo on the د. The sound springs and stops.

AVOID ✗
أَحَدَ / أَحَدِ

Don’t add a vowel. The bounce is neutral — never lean it toward a fat-ha, kasra, or damma.

Your turn

Lighter or stronger?

Each word has a qalqalah letter. Is it a minor bounce (in the middle) or a major bounce (stopping at the end)?
