A good Swahili dictionary tells you more than what a noun means. It may label mtoto as 1/2, m-/wa-, or M-WA; mark tunda as 5/6 even though the singular has no visible ji-; or print an irregular plural beside the headword. These different notations encode the same practical questions: what is the plural, and what agreement does each number control?
There is no single notation shared by every dictionary. Always read the work's abbreviations or front matter before treating a symbol as universal. This page gives the common systems and shows how to turn a compact entry into a usable agreement frame. It does not replace the full concord tables or the practical agreement-based class diagnostic.
All unlabelled examples are neutral Standard Swahili.
Three common ways to label the same noun
Traditional class numbers name each agreement class separately. A slash joins a common singular–plural pairing. Prefix labels instead show memorable noun shapes or concords.
| Dictionary notation | What it means | Typical example |
|---|---|---|
| 1/2 | class 1 singular, class 2 plural | mtoto / watoto |
| m-/wa- or M-WA | the common class 1/2 prefix pair | mgeni / wageni |
| 5/6 | class 5 singular, class 6 plural | tunda / matunda |
| (ji-)/ma-, ø/ma-, or LI-YA | class 5 may have ji- or no overt prefix; class 6 commonly has ma- | jicho / macho; tunda / matunda |
| 7/8 or ki-/vi- | class 7 singular, class 8 plural | kitabu / vitabu |
| 9/10, N/N, or I-ZI | class 9 singular and class 10 plural, often with the same noun form | barua / barua |
| 11/10 or U-N | class 11 singular with an established class 10 plural | uzi / nyuzi |
| 14, U, mass, or no pl. | typically an abstract or mass noun without an ordinary count plural | uzuri |
The learner labels LI-YA and I-ZI often refer to subject concords, not literal noun prefixes. That is why tunda can be on the LI side although it does not begin li- or ji-. Likewise, an unchanged noun such as barua can be I-ZI because its verbs contrast ime-/zime-.
Turning 1/2 into a sentence
Suppose an entry gives mtoto 1/2, plural watoto. The numbers predict human singular and plural agreement, but writing a frame makes the information active.
Mtoto huyu mdogo wangu amelala sebuleni.
This young child of mine has fallen asleep in the living room.
Watoto hawa wadogo wangu wamelala sebuleni.
These young children of mine have fallen asleep in the living room.
The noun pair is mtoto/watoto. Its agreement chain is huyu/mdogo/wangu/ame- versus hawa/wadogo/wangu/wame-. Possessive wangu happens to be identical in these two forms, so the demonstrative, adjective, and verb do more work in showing number.
Some human nouns do not visibly begin m-. A dictionary may still label rafiki as class 1/2 because neutral reference to a human friend uses human agreement. This is one reason numeric labels are more precise than a first-letter mnemonic.
Reading zero-prefix notation
A zero symbol—often ø, a dash, parentheses around a possible prefix, or simply no prefix before the slash—means that no segment is visible in that form. It does not mean “no noun class.”
An entry for tunda/matunda may appear as 5/6, ø/ma-, (ji-)/ma-, or LI-YA, depending on the dictionary's system.
Tunda hili kubwa langu limeanguka kutoka mtini.
This large fruit of mine has fallen from the tree.
Matunda haya makubwa yangu yameanguka kutoka mtini.
These large fruits of mine have fallen from the tree.
The full contrast is hili/kubwa/langu/lime- against haya/makubwa/yangu/yame-. The class 5 zero prefix is deceptive only if you expect the noun's first syllable to be repeated across the sentence.
Zero notation also appears with many loans in classes 9/10. There, both number forms may lack an overt class prefix. Check the dictionary's legend: N can describe the historical or phonological nasal class even when a particular loan has no pronounced nasal.
When the headword does not change
For a 9/10 noun such as meza “table(s),” the dictionary may repeat the noun, give “pl. meza,” or supply only the label 9/10. The agreement frame provides the number contrast.
Meza hii ndefu yangu imewekwa karibu na dirisha.
This long table of mine has been placed near the window.
Meza hizi ndefu zangu zimewekwa karibu na dirisha.
These long tables of mine have been placed near the window.
The deceptive surface form meza stays unchanged, and ndefu also happens to be identical. Singular hii/yangu/ime- and plural hizi/zangu/zime- carry the distinction. Do not add English -s or invent ma- merely to make the plural visible.
Irregular and cross-class plurals
Some entries show a singular in one class and a plural outside the usual adjacent pair. Class 11 nouns frequently take class 10 plurals, and the finished noun may involve prefix loss or a nasal change.
Ukuta huu mrefu wangu umeanguka baada ya mvua.
This long wall of mine collapsed after the rain.
Kuta hizi ndefu zangu zimeanguka baada ya mvua.
These long walls of mine collapsed after the rain.
A dictionary may write ukuta 11/10, “pl. kuta,” or place the two forms in linked entries. Store the lexical plural exactly as printed. The class 10 subject marker zi- is a concord inside zimeanguka; it is not a noun prefix to attach to ukuta.
Other class 11/10 results include uzi/nyuzi “thread(s)” and wimbo/nyimbo “song(s).” Their differing shapes show why a class label predicts agreement more reliably than it predicts the exact spelling of an irregular plural.
Uncountables, mass nouns, and plural-only entries
A label such as no pl., uncount., mass, or class 14 warns that an ordinary count plural is not expected. Uzuri “beauty” takes u-class agreement but normally remains noncount. To count manifestations, name the unit: aina za uzuri “kinds of beauty” or mifano ya uzuri “examples of beauty.”
Some nouns are grammatically plural or collective even when English translates them with a singular mass noun. Maji “water” controls class 6 agreement:
Maji haya yote yameingia jikoni.
All this water has entered the kitchen.
The English translation uses singular “water,” but Swahili haya, yote, and yame- are class 6. A dictionary may label maji 6, pl. only, or mass. These descriptions answer different questions: 6 gives the concord class, while “mass” explains why no ordinary singular–plural count pair is listed.
When a noun has both a mass use and a countable use, read the numbered senses separately. A plural may mean portions, kinds, products, or distinct cases rather than “more of the same substance.”
A reliable dictionary routine
For each new noun:
- Read the dictionary's notation key.
- Copy the singular and the attested plural, including an unchanged plural.
- Note “no ordinary plural” or “plural only” when stated.
- Convert the number label into one subject verb and one demonstrative.
- Check human or animate meaning before applying inanimate concord mechanically.
This routine separates noun morphology from syntactic agreement. They normally reinforce each other, but human nouns, animals, loans, zero-prefix nouns, and irregular plurals are exactly where the distinction matters.
Common Mistakes
Reading 5/6 as part of the word
❌ Litunda hili limeiva.
Incorrect — LI names the class 5 subject concord in the learner label, not a noun prefix to add to tunda.
✅ Tunda hili limeiva.
This fruit has ripened.
Adding an English plural to an unchanged noun
❌ Mezas hizi zimewekwa nje.
Incorrect — the established class 10 plural remains meza.
✅ Meza hizi zimewekwa nje.
These tables have been placed outside.
Inventing a regular plural instead of using the listed one
❌ Miukuta hii imeanguka.
Incorrect — the established plural of ukuta is kuta with class 10 agreement.
✅ Kuta hizi zimeanguka.
These walls have collapsed.
Copying the noun prefix onto concords
❌ Matunda mahaya mangu mayameiva.
Incorrect — class 6 uses haya, yangu, and yameiva.
✅ Matunda haya yangu yameiva.
These fruits of mine have ripened.
Key Takeaways
Numeric labels, slash notation, and prefix-pair names are alternative maps to noun morphology and agreement. A zero prefix is still part of a class analysis; an unchanged plural still controls plural concord; and mass or plural-only labels describe number behavior as well as meaning. Read each dictionary's legend, record explicit plural forms, and turn the entry into a short agreement frame before using it.
