This page gathers basic information about the Adlam script and its use for the Pular language. It aims (generally) to provide an overview of the orthography and typographic features, and (specifically) to advise how to write Pular using Unicode.
The level of detail in the phonetic transcriptions shown below may vary according to the source. The transcriptions are generally intended to merely give an idea of the pronunciation.

The Adlam script was devised in the 1980s, and is nowadays used for writing the Fulani language, alongside Latin and Arabic orthographies. It is currently taught in Guinea, Nigeria, Liberia and other nearby countries.
Pular or Pulaar is the way the Fula people refer to their language in western dialects. In central and eastern dialects it is Fulfulde. The English names Fula(h) and Fulani originally come from Manding and Hausa, respectively. Sometimes the French name Peul (from Wolof) can be found.
The spread of the script is occurring remarkably rapidly across the whole Pular/Fulfulde-speaking world, through a grass-roots movement. The new script appeals to Pular speakers, and its use is having a positive impact on general literacy among them.
𞤀𞤣𞤤𞤢𞤥 𞤆𞤵𞤤𞤢𞤪 Adlam Pular
The script was developed by two teenage brothers, Ibrahima and Abdoulaye Barry, so that their language could have its own script. The name of the script ‘Adlam’ reflects the first four characters in the repertoire: A, D, L, and M.
After teaching their own family and local villagers to use the script for lessons in water hygiene and basic medical care, the brothers set up learning centres in Togo, Senegal, and Benin. Eventually, the means were available to print the script, and a newspaper and a number of printed books were published.
The shapes of the glyphs used has evolved over time, and various changes were standardised in 2019, however some fonts have not yet caught up with these changes.

The Adlam script is an alphabet. Both consonants and vowels are indicated by letters. See the table to the right for a brief overview of features for the Pular language.
Adlam text runs right-to-left in horizontal lines. Unlike Arabic, numbers are also written right-to-left.
The script can be written cursively or not. Non-joining fonts may be used for titles, etc.
Adlam is bicameral, so all the numbers below need to be doubled to account for upper- and lowercase variants.
The 23 native consonant letters used for Fulah are supplemented by repertoire extensions for 6 more sounds used in foreign and loan words, and by applying a consonant modifier diacritic or a nukta to 9 characters for more foreign (mostly Arabic sounds).
There is no special treatment for consonant clusters or final consonants.
Diacritics are also used to indicate prenasalisation and gemination.
Adlam has 7 basic, short vowel sounds, but only 5 vowel letters. A nukta is used to create 2 more letters. Long vowels are indicated using one of the 2 vowel lengthening diacritics.
Adlam has a set of native numerals. Numbers are written from right-to-left, and therefore do not create bidirectional text.
Click on the sound groups to see where else in the document each of the sounds are referred to.
Phones in a lighter colour are infrequently used. Source Wikipedia.
Short i e o u vowel sounds can also be realized as ɪ ɛ ɔ ʊ.wl
|fricative||f v||θ||s z
|ʃ||x ɣ||ʕ||h ɦ|
The basic vowels are written as follows:
The sounds e and o are less frequent and are written using 𞥊 [U+1E94A ADLAM NUKTA] over the open-mid vowels.
Long vowel sounds are indicated using diacritics. There are 2 of these: 𞥅 [U+1E945 ADLAM VOWEL LENGTHENER] is used for all vowels except 𞤢 [U+1E922 ADLAM SMALL LETTER ALIF], which uses 𞥄 [U+1E944 ADLAM ALIF LENGTHENER]. Note how the shape varies when used with upper- and lowercase letters.
The 𞥊 [U+1E94A ADLAM NUKTA] used to distinguish sounds e and o normally appears above the base letter, but when the sound is lengthened the diacritic should appear below the base character, while the lengthening mark appears above, eg. 𞤫𞥊𞥅 ɛ˙ː eː 𞤮𞥊𞥅 ɔ˙ː oː The nukta should be typed and stored before the lengthening mark.
According to Eversone, 𞥄 [U+1E944 ADLAM ALIF LENGTHENER] can also be used above a consonant to indicate the sound aː without a vowel, eg. 𞤣𞥄 dˉ daː
The latest glyph reform introduces visual differences between the shapes of the vowel lengthener (and to a lesser extent, the alif lengthener) above upper vs lowercase letters.p
No special mechanism is used to indicate the absence of a vowel. See also gemination.
The following tables show how the above vowel sounds map to common characters or sequences of characters. The lighter coloured phones are infrequently found.
The following are the consonants in the Adlam alphabet.
A set of supplementary letters are used for loan words and proper nouns originated in neighbouring ethnic groups.
Adlam has 3 diacritics for extending letters to cover non-native sounds (principally Arabic).
𞥈 [U+1E948 ADLAM CONSONANT MODIFIER] and 𞥊 [U+1E94A ADLAM NUKTA] provide the basic diacritics. They are shown here with lowercase letters.
The third diacritic, 𞥉 [U+1E949 ADLAM GEMINATE CONSONANT MODIFIER], is used when one of these modified letters is also geminated.
When a consonant is followed immediately by a glottal stop and then a vowel, the glottal stop is represented using the diacritic 𞥇 [U+1E947 ADLAM HAMZA] over the preceding consonant (see fig_glottal_stop).e,2
Pre-nasalised consonants are indicated by adding 𞥋 [U+1E94B ADLAM NASALIZATION MARK] between NA and the consonant affected, eg. compare 𞤸𞤭𞤲𞥋𞤣𞤵 hin˜du (hi.ndu) it 𞤸𞤭𞤲𞤣𞤵 hindu (hin.du) ancient
In word-initial position, the same logic is applied, and so the word begins with 𞤲𞥋, eg. 𞤲𞥋𞤺𞤵𞤪𞤫
If it appears between two joined letters, the nasalisation character should not break that join.
This character was added to Unicode version 12. Prior to that, people used an apostrophe, but that is not desirable, because it breaks the cursive joining.
Gemination of consonants is normally indicated using 𞥆 [U+1E946 ADLAM GEMINATION MARK],e,2 eg. compare 𞤧𞤢𞤳𞤫 𞤧𞤢𞤳𞥆𞤫
As mentioned in nukta, letters that have consonant modifier diacritics use a special code point, 𞥉 [U+1E949 ADLAM GEMINATE CONSONANT MODIFIER] that combines the gemination marker with the modifier.
Letters that combine with 𞥊 [U+1E94A ADLAM NUKTA] should move that diacritic below the base character and keep the gemination mark above, eg. see fig_gemination.
The following tables show how the above consonant sounds map to common characters or sequences of characters. The lighter coloured phones are infrequently found.
The Adlam block has no symbols.
Adlam uses native digits.
Unlike other right-to-left scripts such as Arabic, Hebrew, and Thaana, (but like N'Ko) the numbers are displayed right-to-left, with the most significant digit first.e This means that numbers don't produce bidirectional text in Adlam
The shape of 𞥖 [U+1E956 ADLAM DIGIT SIX] was significantly changed by the 2019 glyph shape reform to make it less similar to the letter HA.p
For thousands and decimal separators, Adlam uses a space and a period, respectively.n
Adlam text is written horizontally, with successive lines progressing down the page.
Inline text is right-to-left in the main but, as in most right-to-left scripts, embedded left-to-right script text is written left-to-right (producing 'bidirectional' text). However, like N'Ko but unlike Arabic, numbers are also written with digits in right-to-left order.
The Unicode Bidirectional Algorithm automatically takes care of the ordering for all the text in fig_bidi, as long as the 'base direction' is set to RTL. In HTML this can be set using the
dir attribute, or in plain text using formatting controls.
If the base direction is not set appropriately, the directional runs will be ordered incorrectly as shown in fig_bidi_no_base_direction.
bidi_class properties for characters in the Fula language.
For other aspects of dealing with right-to-left writing systems see the following sections:
For more information about how directionality and base direction work, see Unicode Bidirectional Algorithm basics. For information about plain text formatting characters see How to use Unicode controls for bidi text. And for working with markup in HTML, see Creating HTML Pages in Arabic, Hebrew and Other Right-to-left Scripts.
Unicode provides a set of 10 formatting characters that can be used to control the direction of text when displayed. These characters have no visual form in the rendered text, however text editing applications may have a way to show their location.
U+202B RIGHT-TO-LEFT EMBEDDING] ( [RLE), U+202A LEFT-TO-RIGHT EMBEDDING] ( [LRE), and U+202C POP DIRECTIONAL FORMATTING] ( [PDF) are in widespread use to set the base direction of a range of characters. RLE/LRE comes at the start, and PDF at the end of a range of characters for which the base direction is to be set.
In Unicode 6.1, the Unicode Standard added a set of characters which do the same thing but also isolate the content from surrounding characters, in order to avoid spillover effects. They are U+2067 RIGHT-TO-LEFT ISOLATE] ( [RLI), U+2066 LEFT-TO-RIGHT ISOLATE] ( [LRI), and U+2069 POP DIRECTIONAL ISOLATE] ( [PDI). The Unicode Standard recommends that these be used instead.
There is also U+2068 FIRST STRONG ISOLATE] ( [FSI), used initially to set the base direction according to the first recognised strongly-directional character.
U+061C ARABIC LETTER MARK] ( [ALM) is used to produce correct sequencing of numeric data. Follow the link for details.
U+200F RIGHT-TO-LEFT MARK] ( [RLM) and U+200E LEFT-TO-RIGHT MARK] ( [LRM) are invisible characters with strong directional properties that are also sometimes used to produce the correct ordering of text.
For more information about how to use these formatting characters see How to use Unicode controls for bidi text. Note, however, that when writing HTML you should generally use markup rather than these control codes. For information about that, see Creating HTML Pages in Arabic, Hebrew and Other Right-to-left Scripts.
This section brings together information about the following topics: writing styles; cursive text; context-based shaping; context-based positioning; baselines, line height, etc.; font styles; case & other character transforms.
You can experiment with examples using the Adlam character app.
Adlam is usually cursive, ie. letters in a word are joined up (see cursive and fig_joined_writing_style), however a non-cursive writing style (see fig_unjoined_writing_style) is sometimes used, mainly as display fonts for books and article titles as well as educational content (because the unconnected script is easier to learn).n
When Adlam is cursive (see writing_styles), letters in a word are joined up. Fonts need to produce the appropriate joining form for a letter, according to its visual context, but the code point remains the same. This results in four different glyphs for most letters (including an isolated glyph).
The cursive treatment doesn't produce major variations of the essential part of the glyph for a character (unlike Arabic), but there are some small adaptations.
Unlike Arabic and Syriac scripts, no glyphs join only on one side.
Unlike Arabic or Syriac, and with one very minor exception (highlighted in the table) joining forms only differ by the addition of a small baseline extension. Also, whereas Arabic and Syriac re-use a number of basic shapes to create additional letters by adding diacritics, in Adlam each letter shape is different. fig_joining_forms shows the basic shapes in Adlam and what their joining forms look like.

U+200D ZERO WIDTH JOINER] ( [ZWJ) and U+200C ZERO WIDTH NON-JOINER] ( [ZWNJ) are used to control the visual joining behaviour of cursive glyphs. They are particularly useful in educational contexts. For example, the ZWJ was used to create the shapes in fig_joining_forms.
ZWJ permits a letter to form a cursive connection without a visible neighbour.
ZWNJ prevents two adjacent letters forming a cursive connection with each other when rendered.
Observation: The ZWJ only works on the left side of glyphs in fig_joining_forms if the table cell's base direction is set to RTL.
See just above for shaping related to cursive joining.
See variants for information about recent glyph shape changes.
Context affects the shapes of certain diacritics when placed over upper vs lowercase letters.p
𞥊 [U+1E94A ADLAM NUKTA] usually sits above the letter it modifies, but if the letter is also lengthened or geminated, it moves below the letter and leaves the lengthening/gemination diacritic above.
The Kigelia font may be the first italicised Adlam tyeface, but its development was based on requests from the community of users. Discussion with the community led to an italic form that leans to the right (unlike N'Ko).g,#issuecomment-512911833
Adlam is bicameral, so it is useful to be able to convert automatically between upper and lowercase characters.
Adlam words are separated by spaces.
: [U+003A COLON]
. [U+002E FULL STOP]
The question mark, ؟ [U+061F ARABIC QUESTION MARK], is from the Arabic block, but the comma and semicolon are ⹁ [U+2E41 REVERSED COMMA] and ⁏ [U+204F REVERSED SEMICOLON], respectively, rather than the Arabic comma and semicolon. (The Arabic comma/semicolon are only used as carryovers from the older Adlam fonts.)n
𞥟 [U+1E95F ADLAM INITIAL QUESTION MARK] and 𞥞 [U+1E95E ADLAM INITIAL EXCLAMATION MARK] are used to begin a phrase that is a question or exclamation, respectively, much like ¿ and ¡ in Spanish. The phrase ends using an Arabic question mark or ASCII exclamation mark,e,2 eg. 𞥟 𞤢𞤤𞤢𞥄 ؟ ¿ alaˉ ? no? 𞥞𞤢𞤤𞤢𞥄 ! ¡ alaˉ ! no!
The shapes of these question and exclamation punctuation marks were significantly changed in the 2019 shape reform, with the aim of making them more visually appealing.
Observation: The punctuation marks appear to be separated from the rest of the text by a space.
The words 'left' and 'right' in Unicode names for parentheses, brackets, and other paired characters should be ignored. LEFT should be read as if it said START, and RIGHT as END. The direction in which the glyphs point will be automatically determined according to the base direction of the text.
The number of characters that are mirrored in this way is around 550, most of which are mathematical symbols. Some are single characters, rather than pairs. The following are some of the more common ones.
Observation: Adlam text appears to use quote marks “ [U+201C LEFT DOUBLE QUOTATION MARK] at the start, and ” [U+201D RIGHT DOUBLE QUOTATION MARK] at the end. Note that these characters are not mirrored during display. This means that left indicates use on the left, and right indicates use on the right, unlike other types of paired punctuation.
Observation: Adlam text appears to use the 3-dot ellipsis. Unicode has … [U+2026 HORIZONTAL ELLIPSIS] for that.
Adlam text breaks primarily at the spaces around words.
Show (default) line-breaking properties for characters in the Fula language.
When a line break occurs in the middle of an embedded left-to-right sequence, the items in that sequence need to be rearranged visually so that it isn't necessary to read lines from top to bottom.
latin-line-breaks shows how two Latin words are apparently reordered in the flow of text to accommodate this rule. Of course, the rearragement is only that of the visual glyphs: nothing affects the order of the characters in memory.
Fula text uses hyphenation at the end of a line to reduce excess space during justification. See an example in fig_hyphenation.
Fully-justified text in Fulah is produced by adding spaces between words, but long words may be hyphenated to reduce the overall space added.g
See also historical_justification.
You can experiment with counter styles using the Counter styles converter. Patterns for using these styles in CSS can be found in Ready-made Counter Styles, and we use the names of those patterns here to refer to the various styles.
The Pular orthography uses a numeric style using native digits.
The adlam numeric style is decimal-based and uses these digits.rmcs
The default list style uses a full stop + space as a suffix.
Observation: The Winden Jangen site has scans of a number of books which use ordered lists, and they use Adlam numbers (see fig_cs_numeric).
Drop caps can be found in Fulah text written with the Adlam script (more commonly than raised caps).
The initial character is an unjoined form.
This section is for any features that are specific to thisScript and that relate to the following topics: general page layout & progression; grids & tables; notes, footnotes, etc; forms & user interaction; page numbering, running headers, etc.
Pular books, magazines, etc. written using the Adlam script are bound on the right-hand side, and pages progress from right to left.
Columns are vertical but run right-to-left across the page.
The right-to-left orientation of the script affects the direction of page layout, and of the layout of items within the page.
The page shown in fig_layout is the mirror-image of pages in, say, French. Note the various navigation items on the page, and the progression of numbers at the bottom of the page.
On the other hand, the video controls assume a LTR direction. This is mostly constrained by technology at the moment, and whether or not this is acceptable is still being debated.
In 2019 the design of Adlam letter glyphs was overhauled in a proposal to the Unicode Consortium, which resulted in changes to the code chart. p
Typical changes involved standardising the shapes across cursive forms, better distinctions between lower and uppercase forms, removal of some ascenders to avoid diacritic collisions, and then addition of some small ascenders to help distinguish joined forms.
There were also some significant shape changes, particularly to make supplementary letters look more like those used for similar, standard sounds, or to make letters easier to read.
Although there are not many Adlam Unicode fonts, and they will be changed, legacy forms are likely to persist for some time alongside the new forms.
The 2017 release of the Noto Sans Adlam font (still in use in early 2020) contained a set of glyphs that sometimes matched one or other of the shapes shown in variant_shapes, and sometimes used completely different shapes from either. The Noto fonts were updated to the new shapes in September 2020.
Click to also show in variant_shapes shapes produced by the Noto Sans Adlam font at the start of 2020. Red underlines highlight some characters that don't resemble either of the other charts.
In the early stages of Adlam typography it was quite common to see full justification of printed text that was produced by stretching baselines, rather than by adjusting inter-word spaces. This was influenced by the use of keyboards based on Arabic code points. Handwritten documents, however, were not justified in this way.
Observation: The Winden Jangen site has scans of a number of books which apply full justification. The method of justification appears to be elongation of the baseline, with no affect on the inter-word spacing. See fig_justification. In narrow columns this can produce some exaggerated stretching, as seen in fig_justification_wide. There are many passages in the samples available that apply this exaggerated stretching. Some content also applies justification to the last line in a paragraph, which sometimes produces even wider elongations.
According to ScriptSource, the Adlam script is used for the following languages:
