Reading the transliteration: what those dots, lines, and half-circles mean

Under every verse in this app you'll find the Arabic written out in Latin letters — bismi-llāhi-r-raḥmāni-r-raḥīm. But look closely and you'll see it's not ordinary English spelling. There are lines over some vowels (ā ī ū), dots under some letters (ḥ ṣ ḍ ṭ ẓ), and two odd little half-circles (ʾ and ʿ). These aren't typos or decoration. They're a precise system, and once you can read them, the transliteration becomes a genuinely reliable guide to pronunciation.

The system is called ALA-LC — the romanization standard of the American Library Association and Library of Congress. Its whole purpose is to be unambiguous: every Arabic letter maps to exactly one symbol, and every symbol means exactly one sound. Ordinary English spelling can't do that — think how many ways English writes the 'oo' sound. ALA-LC removes the guesswork.

The two half-circles: ʾ and ʿ

These trip up almost everyone, and they're two completely different sounds. Getting them right matters — they're full consonants in Arabic, not silent marks.

• ʾ (a small raised comma, opening to the right) is the hamza (ء) — a glottal stop. It's the tiny catch in your throat in the middle of uh-oh. In ʾiman or masʾalah, you briefly stop the airflow.
• ʿ (a small raised comma, opening to the left) is ʿayn (ع) — a deep, tightened sound from low in the throat, with no English equivalent. It's the sound at the start of ʿAbd and ʿilm. Think of a gentle throat-tightening, almost a swallowed vowel; the only real way to learn it is to hear it.

Dots underneath: the heavy (emphatic) letters

A dot under a letter marks an emphatic consonant — a heavier, fuller version made further back in the mouth than its plain cousin. English has only the light versions, so the dot is your reminder to 'weigh it down.'

• ḥ (ح) — a strong, breathy h from deep in the throat, as if fogging a mirror. Different from the plain h (ه).
• ṣ (ص) — a heavy s, versus the light s (س) in sun.
• ḍ (ض) — a heavy d, the letter so distinctive that Arabic is called 'the language of the ḍād.'
• ṭ (ط) — a heavy t, versus the light t (ت).
• ẓ (ظ) — a heavy version of the th in this, pronounced fuller and further back.

Two letters written as pairs

Some Arabic letters are written with two Latin letters because they're single sounds English spells that way. Read each pair as one sound, never two:

• th (ث) — the th in think (voiceless).
• dh (ذ) — the th in this (voiced).
• kh (خ) — like the ch in Scottish loch or German Bach; a raspy sound from the back of the mouth.
• sh (ش) — the sh in ship.
• gh (غ) — like a gargled French r; a guttural sound close to ʿayn but rougher.

One more single letter worth flagging: q (ق) is not the English k. It's a k made right at the very back of the throat, deeper and heavier — as in Qurʾān itself.

Lines over vowels: hold them longer

The line over a vowel is a macron, and it means one simple thing: stretch it. A long vowel is held about twice as long as a short one, and mixing them up can change a word's meaning entirely.

• a i u — short vowels: a quick a as in cup, i as in sit, u as in put.
• ā — a long a as in father (qāla, 'he said').
• ī — a long ee as in see (raḥīm).
• ū — a long oo as in moon (nūr, 'light').
• aw / ay — diphthongs (two vowels gliding together), as in how and hay (yawm, 'day'; khayr, 'good').

Doubled letters and the 'al-'

Two last patterns you'll see constantly:

• A doubled consonant (as in raḥmānir-raḥīm or rabb) marks the Arabic shadda — you dwell on the letter, pressing it firmly rather than saying it once quickly.
• al- is the definite article ('the'). Before most letters it stays al- (al-ḥamd), but before the 'sun letters' it blends into the next sound and doubles it: ash-shams (not al-shams), ar-raḥmān (not al-raḥmān). The transliteration shows you exactly how it's actually recited, with the words linked by hyphens the way they flow in recitation.

Put it together

Take ar-raḥmāni-r-raḥīm. Now you can read it precisely: the article blended into a doubled r; the heavy, breathy ḥ; the long, held ā and ī. That's a world away from guessing at 'rahman raheem,' and it's the difference the dots and lines are there to make.

Use the transliteration as training wheels, not a crutch. Let it guide your tongue while your eyes slowly learn the Arabic above it — and let a teacher's voice correct the sounds no writing can fully capture. The goal, always, is to leave the romanization behind and read the Book in the letters it was revealed in.
