Converting boko to Hausa Ajami is a mapping between Hausa sounds, not between the names or values of English and Arabic letters. Boko c represents /tʃ/, j represents /dʒ/, sh and ts each represent one consonant, and ɓ ɗ ƙ are not decorative versions of b d k. A good Ajami transcription begins from that Hausa inventory.
This page uses a fully vowelled, digitally encoded Warsh/Kano-style inventory (pedagogical reference convention). Hafs-based publications, historical manuscripts, regions, and individual authors use alternatives. The table is a decoding map for this convention—not a universal alphabet imposed on every Ajami text.
For the articulatory system behind ɓ, ɗ, ƙ, and ts, see Glottalized Consonants as an Articulatory Class.
The core consonant map
| Boko | Reference Ajami | Hausa sound | Variation note |
|---|---|---|---|
| b | ب | plain /b/ | Stable base letter; some older systems also reused it for ɓ. |
| ɓ | ݑ | implosive /ɓ/ | Warsh reference; ٻ is the Hafs form, while پ and plain ب also occur as alternatives. |
| t | ت | /t/ | Widely stable. |
| c | ث | /tʃ/ | The value is Hausa c, not Arabic /θ/. |
| j | ج | /dʒ/ | Also occurs in loans with related realizations. |
| d | د | plain /d/ | Stable base letter. |
| ɗ | ط | implosive /ɗ/ | Some authors reuse د; the dedicated contrast is clearer. |
| k | ک | plain /k/ | Warsh form; Hafs-based text generally uses ك. |
| ƙ | ࢼ | ejective /kʼ/ | Warsh reference; ق is common in Hafs-based practice, and ك also occurs in less differentiated systems. |
| g | غ | /g/ | Do not give it the Modern Arabic /ɣ/ value. |
| f | ࢻ | /ɸ ~ f/ | Warsh reference; ف is Hafs-based, and پ also occurs. |
| s | س | /s/ | ص may be retained in Arabic loans. |
| ts | ڟ | Standard/Kano usually [sʼ] | [tsʼ] and [tʃʼ] are regional realizations. |
| z | ز | /z/ | ذ and ظ occur as alternatives or in loans. |
| sh | ش | /ʃ/ | One consonant, not s plus h. |
| h | ح | Hausa /h/ | Hafs/Naskh-oriented texts commonly use ه; it is also frequent in Quranic names and other author traditions. |
| m | م | /m/ | Widely stable. |
| n | ࢽ | /n/ | Warsh reference; ن is Hafs-based. |
| w | و | /w/ | The same letter also participates in long u/o and au spellings. |
| r | ر | either Hausa r phoneme | Like ordinary boko, the reference spelling does not distinguish the two r sounds. |
| l | ل | /l/ | ض occurs as an occasional alternative. |
| y | ی | /j/ | Warsh reference; Hafs/Naskh-oriented text generally uses ي. Do not confuse consonantal yeh with the dotless sign used in long ī. |
| ’ | ع | glottal stop /ʔ/ | Initial carriers and lexical glottal stops require contextual analysis. |
| ’y | ۑ | /ʔʲ/ or /j̰/ | Nigerian boko ’y; ؿ is another Ajami analysis/convention. |
The articulatory distinctions matter. Ɓ and ɗ are implosives made with larynx lowering and reduced oral pressure, not with audible inhalation. Ƙ is ejective. Standard/Kano ts is taught here primarily as an ejective alveolar fricative [sʼ], while [tsʼ] and [tʃʼ] must be labelled (regional). An English speaker who turns these into plain voiced or voiceless stops changes words even if the rest of the sentence is clear.
Stable sounds versus variable letter choices
The sound inventory is more stable than the handwritten symbols used for it. A differentiated text must somehow keep plain k apart from ejective ƙ, for example, but Warsh-oriented and Hafs-oriented publications need not choose the same qāf-shaped character. Likewise, n may appear as the dot-shifting Warsh letter ࢽ or ordinary ن, and f may appear as ࢻ or ف. These are not different Hausa pronunciations merely because the dots move.
Use a document-internal comparison. Find a high-frequency word whose boko reading is secure, identify its letter choice, and then apply that value elsewhere in the same hand or edition. This is safer than switching conventions midway through a word because one glyph resembles a familiar Arabic letter.
Arabic loanwords add a second layer. A writer may preserve ص, ذ, ظ, ه in a learned spelling (religious/formal or author-specific) even where everyday Hausa pronunciation has merged that contrast with s, z, or h. The spelling can therefore signal etymology or register without demanding a Classical Arabic pronunciation in an ordinary Hausa sentence.
بَبَّ
babba
Big — initial plain b and medial geminated b.
رَاݑَا
raɓa
Dew — the dedicated ɓ letter preserves the implosive contrast in this convention.
طَیَ
ɗaya
One — ɗ is written with the dedicated emphatic-shaped letter in the reference system.
کُوغِى
kogi
River — plain k begins the word; the letter used for g has Hausa /g/.
ڟُوحُو
tsoho
Old — ts is one specialized consonant; both o vowels are long.
Digraphs and modified velars
Boko sh and ts are two-character spellings for single consonants. Ajami correspondingly uses one consonant letter for each. Boko kw, ky, gw, gy, ƙw, ƙy represent labialized or palatalized velars. A major modern Ajami solution adds a small three-dot wagaf distinction to the base letter:
| Boko series | Reference Ajami base | What remains to be recovered |
|---|---|---|
| kw / ky | ݣ | Labialization versus palatalization from the following vowel, word, or an additional glide in conventions that write one. |
| gw / gy | ࣃ | The same lexical/contextual distinction. |
| ƙw / ƙy | ࣄ | Ejective velar plus labialization or palatalization. |
ࣄُثٜىٰ
ƙwace
Snatch or take away — a documented spelling with the modified ƙ-series letter.
ࣄَالّٜىٰ
ƙyalle
Cloth — a documented spelling with the same modified ƙ-series base in a palatalized word.
شٜىٰکَرَا
shekara
Year — sh is one letter, followed by the long-e sequence in this reference spelling.
The three-dot solutions are relatively recent as standardized Unicode characters, though the scribal devices behind them are older. Fonts may render the dots and Kano-style bodies very differently. Older manuscripts may instead spell a glide explicitly, merge the modified consonant with the plain one, or use an author's special mark. These are (historical/author-specific) practices, not learner errors.
Word-medial and word-final correspondences
Do not learn only isolated initial letters. Cursive shaping changes the visible form, and a final consonant normally takes sukūn in a fully vowelled reference spelling.
غَجٜىٰرٜىٰ
gajere
Short — j occurs word-medially, and both e vowels are long in this form.
بِرْجِکْ
birjik
Plentiful — medial j and word-final k; sukūn shows that no vowel follows the final consonant.
ۑَاۑَا
’ya’ya
Children or offspring — Nigerian boko ’y corresponds here to the Warsh-style dedicated letter.
The final k in birjik must not acquire an English release vowel. Conversely, the final written vowel in many Hausa words is real and may be long. Reading every Roman letter with its English value or every Arabic-shaped letter with its Arabic value destroys these contrasts.
Careful and conversational reading
سُࢽَا دَ مُوتَا.
Suna da mota.
They have a car.
At (formal/careful speed), identify each consonant before blending the phrase: s-n, d, m-t, with the written vowels and lengths. At (informal conversational speed), coarticulation makes transitions smoother, but no new English consonants appear and the long vowels do not become optional. The same Ajami spelling serves both readings.
For a listening contrast, compare plain b in babba with implosive ɓ in raɓa, plain d with ɗ in ɗaya, and plain s with ejective ts in tsoho. The words are not minimal pairs, so listen to the target consonant in several recordings rather than inferring the contrast from these meanings alone.
Common Mistakes
1. Collapsing ɓ into plain b
❌ رَابَا
Incorrect in the differentiated reference convention — plain b has replaced ɓ.
✅ رَاݑَا
raɓa
Dew — the dedicated implosive letter preserves ɓ.
2. Writing ɗ with plain d
❌ دَیَ
Incorrect in the differentiated reference convention — this begins with plain d.
✅ طَیَ
ɗaya
One — the reference spelling uses the dedicated ɗ letter.
3. Treating ts as t plus s
❌ تُسُوحُو
Incorrect — two consonants and an extra vowel have replaced the single Hausa ts sound.
✅ ڟُوحُو
tsoho
Old — one specialized letter represents ts.
4. Giving g its Arabic value
❌ کُوغِى
Incorrect performance if the medial letter is given Arabic gh; the boko reading is still kogi.
✅ کُوغِى
kogi
River — pronounce a Hausa voiced velar stop /g/.
Key Takeaways
- Convert Hausa sounds, not English letter names or Arabic letter values.
- A differentiated modern inventory keeps b/ɓ, d/ɗ, k/ƙ, s/ts apart.
- Sh and ts are single Hausa consonants even though boko writes two characters.
- Modified velars have dedicated modern solutions, but manuscript practice varies.
- Warsh and Hafs letters may differ in shape and Unicode identity while representing the same Hausa sound.
