Connecting Letters and Reading

You now know all 28 letters and the diacritic system. This lesson brings everything together — we will learn how letters connect to form words, practise reading connected text, and cover the important topic of sun and moon letters with the definite article ال (al-).

How Letters Connect

Arabic is a cursive script — letters within a word are connected in a flowing line (with breaks only at non-connecting letters). Each letter's form depends on its position:

Position	When It Occurs	Form Used
Initial	First letter of a connected segment	Initial form
Medial	Between two other connected letters	Medial form
Final	Last letter of a connected segment	Final form
Isolated	Standing alone or after a non-connector	Isolated form

Step-by-Step: Connecting بَيت (bayt — house)

Letters:  ب + ي + ت
Step 1:   بـ    (Baa in initial form — connecting to the right)
Step 2:   ـيـ   (Yaa in medial form — connecting both sides)
Step 3:   ـت    (Taa in final form — connecting from right only)
Result:   بَيت

Step-by-Step: Connecting دَرَسَ (darasa — he studied)

Letters:  د + ر + س
Step 1:   د     (Daal — non-connector, stays isolated)
          [break — Daal doesn't connect left]
Step 2:   ر     (Raa — non-connector, stays isolated)
          [break — Raa doesn't connect left]
Step 3:   سَ    (Siin — starts in initial form after a break)
Result:   دَرَسَ  (three separate segments!)

The Six Non-Connecting Letters — Review

Remember: these six letters never connect to the left:

Letter	Name	When it appears mid-word...
ا	Alif	Breaks the chain; next letter starts fresh
د	Daal	Breaks the chain
ذ	Dhaal	Breaks the chain
ر	Raa	Breaks the chain
ز	Zay	Breaks the chain
و	Waaw	Breaks the chain

Tip: Memorise them with the mnemonic: ا د ذ ر ز و — "Alif, Daal, Dhaal, Raa, Zay, Waaw" or remember the phrase "a door is a way" for the first letters of their names.

The Definite Article: ال (al-)

Arabic has only one definite article: ال (al-), equivalent to English "the". It is always written as a prefix attached to the word:

كِتاب  = kitaab  = a book
الكِتاب = al-kitaab = the book

How ال Connects

The Alif (ا) is non-connecting, but the Laam (ل) connects to the following letter:

ال + كتاب = الكتاب
     ↑ Laam connects to Kaaf

Sun and Moon Letters

When ال is followed by certain consonants, the Laam changes its pronunciation. This creates two categories of letters:

Moon Letters (الحروف القمرية)

With moon letters, the Laam of ال is pronounced normally as "l":

Moon Letters	Example	Pronunciation
ا ب ج ح خ	الباب	al-baab (the door)
ع غ ف ق ك	القَمَر	al-qamar (the moon)
م ه و ي	الماء	al-maa' (the water)

There are 14 moon letters.

Sun Letters (الحروف الشمسية)

With sun letters, the Laam of ال is not pronounced — instead, the following consonant is doubled (assimilated):

Sun Letters	Example	Written	Pronounced
ت ث د ذ	الدَرس	al-dars	ad-dars (the lesson)
ر ز س ش	الشَمس	al-shams	ash-shams (the sun)
ص ض ط ظ	الصَباح	al-sabaah	as-sabaah (the morning)
ل ن	اللَيل	al-layl	al-layl (the night)

There are 14 sun letters.
