Hausa often combines yi “do, make, become” with a quality noun when a property is viewed as a development, a result, or an overall judgment. Thus Rigar ta yi kyau can mean “The gown turned out well” or “The gown now looks good.” The completed subject–TAM marker changes with the subject; yi and the following quality noun do not.
This construction is not a universal translation of English “be + adjective.” It competes with true adjective + ne/ce and with yana/tana da + quality noun, but each presents the property differently. Unless marked otherwise, the examples are neutral Nigerian Standard Hausa in both (informal) speech and (formal) prose.
For the contrasting non-resultative frame, see Predicative Quality with yana da and tana da.
The completed pattern
The most useful A2 pattern is subject + completed marker + yi + quality noun.
| Subject | Marker | Example |
|---|---|---|
| masculine singular | ya | Gidan ya yi kyau. |
| feminine singular | ta | Motar ta yi kyau. |
| plural | sun | Gidajen sun yi kyau. |
Bayan an fenti gidan, ya yi kyau sosai.
After the house was painted, it looked very good.
An gyara motar, amma ba ta yi kyau ba.
The car was repaired, but it did not turn out well.
Hotunan sun yi kyau; mu aika wa iyalinmu da su.
The photos came out well; let's send them to our family.
Miyar ta yi kauri bayan ta huce.
The soup became thick after it cooled.
The marker agrees with the subject: masculine gida selects ya, feminine mota and miya select ta, and plural hotuna selects sun. The noun kyau “goodness/beauty” remains invariant. English hides both facts under unchanged “was/looked good.”
Result versus an existing quality
Compare tana da kyau with ta yi kyau. The da construction presents a quality as holding; completed yi naturally asks what happened or how something turned out.
Rigar tana da kyau, kuma ta dace da takalman.
The gown is beautiful, and it matches the shoes.
Da aka gama ɗinkin, rigar ta yi kyau.
When the sewing was finished, the gown turned out well.
Ɗakin yana da sanyi saboda na’urar sanyaya.
The room is cool because of the air conditioner.
Da dare ɗakin ya yi sanyi.
At night the room became cold.
The boundary is not mathematical. In a suitable present context, ya yi kyau can be a current judgment—“it looks good” or “that is good”—while still presenting the quality as an achieved or assessed state. Yana da kyau is less result-oriented: the subject simply has the quality.
Common quality nouns after yi
The combination is partly lexical. Frequent pairings include yi kyau “turn out/look good,” yi muni “turn out/become bad,” yi tsawo “become long/tall,” yi kauri “become thick,” yi laushi “become soft,” yi sanyi “become cold,” yi zafi “become hot,” and yi duhu “become dark.” Learn these as Hausa collocations, not as a license to place yi before every noun.
Hanyar ta yi muni bayan ruwan sama.
The road became bad after the rain.
Yaron ya yi tsawo tun bara.
The boy has grown tall since last year.
Gashin ya yi tsawo; lokaci ya yi da za a aske shi.
The hair has grown long; it is time to cut it.
Ruwan ya yi zafi; ka jira kaɗan kafin ka sha.
The water has become hot; wait a little before drinking it.
Gurasa ta yi laushi bayan na rufe ta.
The bread became soft after I covered it.
With weather and environmental conditions, impersonal masculine singular ya is common because the condition is construed generally: Ya yi duhu “It grew dark.” A named feminine subject still selects ta: Unguwar ta yi duhu “The neighborhood became dark.”
Ya yi duhu kafin muka isa gida.
It grew dark before we reached home.
Sama ta yi duhu; wataƙila za a yi ruwa.
The sky became dark; it may rain.
yi does not take adjective agreement here
In Yaron ya yi tsawo, tsawo is the noun “height/length,” not masculine dogo. For a simple property assertion with a true adjective, use the agreeing adjective construction.
| Viewpoint | Hausa | Analysis |
|---|---|---|
| stable description | Yaron dogo ne. | masculine adjective + ne |
| quality possessed | Yaron yana da tsawo. | da
|
| growth/result | Yaron ya yi tsawo. | completed yi + quality noun |
A da yarinyar gajeriya ce, amma yanzu ta yi tsawo.
The girl used to be short, but now she has grown tall.
The feminine subject is visible only on ta. The noun tsawo does not become a feminine form. By contrast, true adjectival doguwa ce shows feminine agreement on both the adjective and copula.
Attributive phrases are built differently
Completed yi makes a clause, not a modifier placed before a noun. To say “a beautiful car,” use a linked adjective or a mai phrase: kyakkyawar mota or mota mai kyau. Then use ta yi kyau when judging the outcome.
Sun kawo kyakkyawar mota daga Kano.
They brought a beautiful car from Kano.
Bayan an wanke motar, ta yi kyau fiye da da.
After the car was washed, it looked better than before.
Mun zaɓi labule masu kauri domin ɗakin.
We chose thick curtains for the room.
Da aka jiƙa labulen, sun yi nauyi.
When the curtains got wet, they became heavy.
This distinction matters because English uses adjective morphology in both “a thick curtain” and “the curtain became thick.” Hausa can use mai kauri attributively but a verbal yi kauri result predicate.
Other TAM forms and viewpoint
Because yi is a verb, its result can also be located in the future. The future marker agrees with the subject just as it does with other verbs.
Ruwan zai yi sanyi idan ka saka shi a firiji.
The water will become cold if you put it in the refrigerator.
For elementary property descriptions, avoid manufacturing forms by analogy. Use established expressions and let the intended viewpoint decide. A result already reached normally favors completed ya/ta/sun yi; a predicted result can use zai/za ta/za su yi; a quality simply held favors yana/tana/suna da; a true adjective favors adjective + ne/ce.
A natural judgment in context
A ganina, tsarin farko ya yi kyau, amma na biyu yana da tsada sosai.
In my view, the first plan turned out well, but the second is very expensive.
The first predicate evaluates an outcome with yi kyau. The second attributes a cost-related quality with yana da tsada. English uses “is/turned out” and makes the contrast look optional; Hausa chooses a construction according to lexical class and viewpoint.
Practice
- A feminine road deteriorated after rain: Hanyar ta yi muni bayan ruwan sama.
- Several pictures came out well: Hotunan sun yi kyau.
- A boy has grown tall: Yaron ya yi tsawo.
- Describe a gown as simply beautiful, without a result reading: Rigar tana da kyau.
Common Mistakes
1. Using one masculine marker for every subject
❌ Motar ya yi kyau.
Incorrect — feminine mota requires ta.
✅ Motar ta yi kyau bayan an gyara ta.
The car looked good after it was repaired.
2. Giving a quality noun adjective agreement
❌ Yarinyar ta yi doguwa.
Incorrect for 'the girl grew tall' — yi selects the quality noun tsawo here.
✅ Yarinyar ta yi tsawo.
The girl grew tall.
3. Using yi for a neutral true-adjective description
❌ Littafin ya yi sabo.
Incorrect for the ordinary statement 'The book is new.'
✅ Littafin sabo ne.
The book is new.
4. Losing the result contrast
❌ An gama ɗinkin, kuma rigar yi kyau.
Incorrect — the result predicate needs the agreeing completed marker ta.
✅ An gama ɗinkin, kuma rigar ta yi kyau.
The sewing is finished, and the gown turned out well.
Key Takeaways
- Completed ya/ta/sun yi plus a quality noun presents change, result, or assessment.
- Agreement appears on the subject–TAM marker; the quality noun stays unchanged.
- Contrast ta yi kyau “it turned out well” with tana da kyau “it is beautiful/good.”
- True adjectives still use agreement + ne/ce: Littafin sabo ne.
- Learn natural yi
- quality-noun collocations rather than translating every English adjective mechanically.
