When lām ل is followed by alif ا, mainstream Arabic typography combines them into the familiar shape لا, called lām–alif. It is a mandatory contextual shape in almost all ordinary print styles and in conventional handwriting, but it is not a twenty-ninth letter. A few experimental modern typefaces draw an unligated sequence; that font choice does not change the spelling, which still contains two base characters, ل followed by ا.
This matters when typing, counting roots, adding vowel marks, and distinguishing لا lā “no/not” from sequences such as لأ liʾ- and لإ liʾ-. English ligatures such as “fi” are often optional decoration; lām–alif is the normal Arabic presentation of this letter sequence.
The four core shapes
The alif may be plain, carry hamza above or below, or carry madda. The lām combines with the whole alif shape, but the hamza or madda remains meaningful.
| Base sequence | Normal combined shape | After a joining letter | Typical reading |
|---|---|---|---|
| ل + ا | لا | ـلا | lā, or l plus ā across a morpheme boundary |
| ل + أ | لأ | ـلأ | l plus pronounced ʾa/ʾu, according to the word |
| ل + إ | لإ | ـلإ | l plus pronounced ʾi |
| ل + آ | لآ | ـلآ | l plus ʾā / ā after the relevant boundary |
In isolation, لا begins with the upright stroke of lām. After a letter that connects forward, as in علا or ملابس, the joining stroke enters from the right: ـلا. The alif then blocks connection to the next letter because ا is one of the six letters ا د ذ ر ز و that never join to a following letter.
لا تقلق؛ سأرسل لك العنوان.
lā taqlaq; saʾursilu laka l-ʿunwān.
Don't worry; I'll send you the address.
The opening لا is two letters even though it appears as one compact form. In العنوان, by contrast, lām is followed by ع, so no lām–alif shape occurs.
Final and medial-looking occurrences
Lām–alif can appear at the end of a word or in the middle of its spelling. What changes is not the identity of the sequence but whether another character follows the alif.
| Word | Analysis | Position of the sequence | Joining result |
|---|---|---|---|
| علا | ع + ل + ا | final | ع joins into ـلا |
| ملأ | م + ل + أ | final, hamzated | م joins into ـلأ |
| سلام | س + ل + ا + م | medial in the spelling | س joins into ـلا; م begins again after nonconnecting ا |
| ملابس | م + ل + ا + ب + س | medial in the spelling | م joins into ـلا; ب starts a new joined segment |
اشترت مريم ملابس للعمل.
ishtarat Maryamu malābisa li-l-ʿamal.
Maryam bought clothes for work.
The visual break between the alif and ب in ملابس is not a word boundary. No space belongs there. Arabic words can contain several disconnected graphic pieces while remaining one orthographic word.
علا صوت الموسيقى، فأغلق سامر النافذة.
ʿalā ṣawtu l-mūsīqā, faʾaghlaqa Sāmirun an-nāfidha.
The music grew louder, so Samer closed the window.
Plain, hamzated, and madda-bearing forms are not interchangeable
The four shapes make a useful confusable set:
- لا is plain lām + alif, as in the negative particle لا lā.
- لأ contains hamza above alif, as in لأن liʾanna “because.”
- لإ contains hamza below alif, often where the preposition لـ meets an إ-initial word: لإدارة li-ʾidāra “for an administration.”
- لآ contains madda, as in لآدم li-Ādam “for Adam.”
تأخرنا لأن الطريق مزدحم.
taʾakhkharnā liʾanna ṭ-ṭarīqa muzdahim.
We were late because the road is congested.
سأرسل نسخة لإدارة الجامعة.
saʾursilu nuskhatan li-ʾidārati l-jāmiʿa.
I will send a copy to the university administration.
هذه الرسالة لآدم، لا لعمر.
hādhihi r-risālatu li-Ādama, lā li-ʿUmar.
This letter is for Adam, not for Omar.
Hamza is pronounced in these examples because it is hamzat al-qaṭʿ. The combined glyph does not erase it. Omitting the mark can create another word: لان may be read لَانَ lāna “became soft,” whereas لأن begins the conjunction “because.”
ملأ الموظف الاستمارة بعناية.
malaʾa l-muwaẓẓafu l-istimārata bi-ʿināya.
The employee filled out the form carefully.
In ملأ, the final alif carries hamza above and is part of the لأ shape. The verb is malaʾa, not malā. Typography cannot substitute for reading the hamza.
What is stored and what the font draws
In well-formed contemporary digital text, type the base letters ل and ا. A shaping engine displays them as لا. Legacy “Arabic Presentation Forms” code points may store a precomposed-looking glyph such as ﻻ, but those characters are (technical/legacy) and can break search, cursor movement, text comparison, and accessibility. They do not belong in ordinary authored MSA.
Vocalization follows the same principle. The ordinary word سلام can receive the audio-ready form سَلَامْ without changing its consonant skeleton. Fatḥa tells the reader how to pronounce the sequence, while the font still shapes lām plus alif.
هذا القرار لا يناسب الجميع.
hādhā l-qarāru lā yunāsibu l-jamīʿ.
This decision does not suit everyone.
The lām in the definite article also forms this shape when the next base letter is alif, but the article has additional rules of its own. See Writing the Definite Article for article attachment and sun-letter spelling.
Common Mistakes
1. Treating لا as one alphabet letter
❌ لا
la
Incorrect reading — the alif makes a long vowel: lā.
✅ لا
lā
Correct — no / not.
There is no short-vowel reading la for the standard negative particle لا. Its two-character spelling also matters when a cursor moves through the word.
2. Inserting a space between the two letters
❌ ل ا تؤجل الموعد.
Incorrect — lām and alif form one written word here.
✅ لا تؤجل الموعد.
lā tuʾajjili l-mawʿid.
Do not postpone the appointment.
3. Dropping hamza from لأن
❌ غادرنا لان المكتب أغلق.
Incorrect in this meaning — “because” is spelled لأن with hamza above.
✅ غادرنا لأن المكتب أغلق.
ghādarnā liʾanna l-maktaba ʾaghlaq.
We left because the office closed.
4. Dropping the below-seat hamza after لـ
❌ أرسلت الطلب لادارة الموارد البشرية.
Incorrect — إدارة begins with إ, which remains visible after attached لـ.
✅ أرسلت الطلب لإدارة الموارد البشرية.
ʾarsaltu ṭ-ṭalaba li-ʾidārati l-mawāridi l-bashariyya.
I sent the request to the human resources department.
Key Takeaways
- لا is the normal shape of two letters, ل + ا, not an extra alphabet letter.
- The variants لأ، لإ، لآ preserve hamza or madda and therefore preserve distinct readings.
- Alif blocks joining to the next letter, even when lām–alif occurs inside a word such as ملابس.
- Type base Arabic letters and let the font shape them; avoid legacy presentation-form glyphs.
