The definite article ال and sun/moon letters

Free Arabic grammar lesson · A1

One article: ال

Arabic has one article, ال (al-), meaning "the". It is joined to the front of the noun and never changes for gender or number. There is no word for "a/an": an indefinite noun simply ends in tanween.

Indefinite Definite
كِتَابٌ (kitābun) a book الْكِتَابُ (al-kitābu) the book
بَيْتٌ (baytun) a house الْبَيْتُ (al-baytu) the house
سَيَّارَةٌ (sayyāratun) a car السَّيَّارَةُ (as-sayyāratu) the car
كُتُبٌ (kutubun) books الْكُتُبُ (al-kutubu) the books

A noun has either ال or tanween, never both.

Moon letters and sun letters

The ل of ال is pronounced only before the 14 moon letters. Before the 14 sun letters it is silent and the next consonant is doubled (shadda). The ل is always written.

Moon letters (l pronounced) Sun letters (l assimilated)
ا ب ج ح خ ع غ ف ق ك م ه و ي ت ث د ذ ر ز س ش ص ض ط ظ ل ن
الْقَمَرُ (al-qamaru) the moon الشَّمْسُ (ash-shamsu) the sun
الْبَابُ (al-bābu) the door الدَّرْسُ (ad-darsu) the lesson
الْمَدْرَسَةُ (al-madrasatu) the school الرَّجُلُ (ar-rajulu) the man
الْوَلَدُ (al-waladu) the boy النُّورُ (an-nūru) the light
الْيَوْمُ (al-yawmu) the day الطَّالِبُ (aṭ-ṭālibu) the student

A practical test: sun letters are made with the tip of the tongue near the teeth (t, d, s, sh, r, n, l...). In writing with harakat, moon letters get a sukun on the ل (الْ), sun letters get a shadda on the next letter (الشَّ).

The vanishing a-

The a of al- is only pronounced at the start of speech. After another word it drops (this alif is called hamzat al-wasl), but it stays in writing:

  • فِي الْبَيْتِ (fi l-bayti) — in the house
  • وَالشَّمْسُ (wa sh-shamsu) — and the sun
  • مِنَ الْمَدْرَسَةِ (mina l-madrasati) — from the school

After the one-letter preposition لِـ (for), the alif is not even written: لِـ + الطَّالِبِ = لِلطَّالِبِ (li ṭ-ṭālibi), for the student.

Where Arabic uses "the" and English does not

Arabic uses ال for things in general and for abstract ideas:

  • أُحِبُّ الْقَهْوَةَ. — I like coffee.
  • الْحَيَاةُ جَمِيلَةٌ. — Life is beautiful.
  • الْعَرَبِيَّةُ لُغَةٌ جَمِيلَةٌ. — Arabic is a beautiful language.

Some place names carry ال as part of the name: الْعِرَاقُ (Iraq), الْقَاهِرَةُ (Cairo), الْمَغْرِبُ (Morocco).

Watch out as an English speaker

  • English speakers pronounce the l everywhere or drop it in writing. ✗ al-shams / ✓ ash-shams, and ✗ اشَّمْسُ / ✓ الشَّمْسُ: the sound assimilates, the spelling does not.
  • Do not add a word for "a". وَاحِدٌ means "one": ✗ وَاحِدٌ كِتَابٌ / ✓ كِتَابٌ (a book).
  • General statements need ال. ✗ أُحِبُّ قَهْوَةً. / ✓ أُحِبُّ الْقَهْوَةَ. (I like coffee.)
  • The article and tanween exclude each other. ✗ الْكِتَابٌ / ✓ الْكِتَابُ.

Example dialogue

أَيْنَ الْكِتَابُ؟ — Where is the book?
الْكِتَابُ فِي الْبَيْتِ. — The book is in the house.
وَأَيْنَ السَّيَّارَةُ؟ — And where is the car?
السَّيَّارَةُ أَمَامَ الْمَدْرَسَةِ. — The car is in front of the school.
شُكْرًا يَا أُسْتَاذُ. — Thank you, sir.
