English weather clauses often begin with a meaningless dummy it: it is raining; it became dark. Hausa has no reason to insert a pronoun referring to nothing. It can make a weather noun such as ruwa “rain/water” or iska “wind” the grammatical subject, use impersonal an/ana, assert existence with akwai, or predicate a condition with yi.
These alternatives present the same environment from different angles. An explicit weather subject highlights an entity or force; an impersonal clause presents an event without naming an agent; an existential introduces a condition into the scene. The wider impersonal paradigm is covered in Impersonal a- and an-Forms. All unlabelled examples are (neutral Nigerian Standard Hausa).
Explicit weather nouns obey ordinary clause order
When a weather noun is the subject, it controls the subject–TAM marker like any other noun. The following transitive clause displays neutral S–TAM–V–O order:
Iska tana kaɗa ƙura a kasuwa.
The wind is blowing dust around the market.
Feminine iska controls tana; ƙura is the direct object of kaɗa. The fact that the subject is not human does not change basic Hausa syntax.
Hadari ya rufe sararin sama da gajimare.
The storm covered the sky with clouds.
Ruwa yana sauka sosai a wajen gari.
Rain is falling heavily outside the town.
Rana tana haskaka filin bayan gajimaren ya watse.
The sun is lighting the field after the clouds have dispersed.
Hadari and ruwa are masculine singular and take ya/yana; feminine rana takes tana. Weather vocabulary does not suspend gender agreement.
Ana ruwa is an impersonal weather expression
The compact expression ana ruwa means that rain is occurring:
Ana ruwa sosai; ku jira a ƙarƙashin rumfar.
It is raining heavily; wait under the shelter.
The a- in ana is impersonal; it does not refer to a hidden masculine it. Ruwa names the environmental event or condition. This established pattern is especially natural when the identity of an agent is irrelevant—which is normally the case with rain.
The completive counterpart commonly uses impersonal an with yi:
An yi ruwa sosai jiya da dare.
It rained heavily last night.
This clause reports a bounded occurrence. The contrast is aspectual and presentational: ana ruwa places the listener inside an ongoing rainy situation, while an yi ruwa packages rainfall as an event.
An ordinary polar question keeps the impersonal marker:
An yi ruwa a garinku jiya?
Did it rain in your town yesterday?
Its negative counterpart uses discontinuous completive negation:
Ba a yi ruwa a nan jiya ba.
It did not rain here yesterday.
Neither question nor negation licenses deleting a/an. Hausa finite predication still needs its subject–TAM marking even though no lexical agent is named.
Yi predicates environmental conditions
Many ambient conditions are expressed with yi plus a quality noun. The grammatical subject can be rana “sun/day,” gari “town/surroundings,” or a quality noun itself, depending on the conventional expression:
Rana ta yi zafi sosai a Azumi.
The day became very hot during the fast.
Gari ya yi duhu kafin ruwan ya fara.
It became dark outside before the rain began.
Sanyi ya yi yawa da sassafe.
The cold was intense early in the morning.
In rana ta yi zafi, feminine rana controls ta and zafi supplies the environmental quality. In gari ya yi duhu, gari does not mean only the built town; in this expression it can evoke the surrounding scene or daylight conditions. English uses dummy it, but Hausa gives the condition a lexical anchor.
The verb waye presents dawn as a change in the scene:
Gari ya waye kafin matafiyan su isa tashar.
Day broke before the travellers reached the station.
This completive can describe the current result of an event—day has dawned—rather than simply locating an event in English past time.
Existential predication introduces what is present
Use invariable akwai when the point is the presence or availability of a weather condition, not an event performed by a subject:
Akwai gajimare da yawa a gabas.
There are many clouds in the east.
Akwai yiwuwar hadari da yamma.
There is a possibility of a storm in the evening.
Negative babu denies existence:
Babu iska yau, shi ya sa ɗakin ya yi zafi.
There is no wind today, which is why the room became hot.
Do not make akwai agree with gajimare or yiwuwar hadari. It is an invariable existential, unlike ruwa yana... or iska tana..., where an overt subject controls agreement.
Choosing among the frames
| Frame | What it foregrounds | Typical example |
|---|---|---|
| Explicit subject | a force or entity | Iska tana kaɗa ƙura. |
| Impersonal | an event with no relevant agent | Ana ruwa. / An yi ruwa. |
| yi + condition | an ambient state or change | Gari ya yi duhu. |
| Existential | presence or absence | Akwai gajimare. / Babu iska. |
These are not four translations of a single English verb. They differ in argument structure. Iska is a subject in iska tana kaɗa ƙura, but the location phrase in an yi ruwa a Kano does not become a subject merely because it can be moved.
Locative focus changes TAM marking
The neutral clause places the location after the weather predicate:
An yi ruwa sosai a Kano jiya.
It rained heavily in Kano yesterday. (neutral)
If speakers contrast Kano with Zariya, the location can be fronted:
A Kano ne aka yi ruwa sosai jiya, ba a Zariya ba.
It was in Kano that it rained heavily yesterday, not in Zariya.
The fronted prepositional phrase a Kano is followed by ne. Crucially, neutral impersonal completive an changes to relative impersonal completive aka. Moving the phrase while keeping an does not form the canonical Hausa focus construction.
The location remains an adjunct: there is no agreement between Kano and aka. The relative marker is required because fronted focus creates a special clause type, not because the place has become the agent of rain.
A short discourse motivates the marked order
—An yi ruwa a Zariya jiya? —A’a, a Kano ne aka yi ruwa sosai. A Zariya kuwa iska ce ta kaɗa ƙura, amma ba a yi ruwa ba. —To, direbobin da suka fito daga Kano za su tarar da hanya a jiƙe.
—Did it rain in Zaria yesterday? —No, it was in Kano that it rained heavily. In Zaria, wind blew dust, but it did not rain. —Then the drivers coming from Kano will find the road wet.
The question establishes a contrast between places, licensing a Kano ne aka.... The next clause switches to explicit feminine iska because the wind itself is now contrasted with rain. Each word order follows the discourse and the predicate’s argument structure.
Common Mistakes
1. Copying English dummy it
❌ Shi yana ruwa.
Incorrect for ‘it is raining’ — shi would refer to an actual masculine entity.
✅ Ana ruwa.
It is raining.
2. Omitting agreement with an explicit weather subject
❌ Iska kaɗa ƙura.
Incorrect as a finite clause — feminine subject marking is missing.
✅ Iska tana kaɗa ƙura.
The wind is blowing dust.
3. Giving the feminine noun iska masculine agreement
❌ Iska yana kaɗawa sosai.
Incorrect — iska is feminine singular.
✅ Iska tana kaɗawa sosai.
The wind is blowing strongly.
4. Negating a completed rain event without final ba
❌ Ba a yi ruwa jiya.
Incomplete Standard completive negation — the closing ba is required.
✅ Ba a yi ruwa jiya ba.
It did not rain yesterday.
5. Fronting a location but keeping neutral an
❌ A Kano ne an yi ruwa sosai.
Incorrect canonical locative focus — neutral an has not changed to relative aka.
✅ A Kano ne aka yi ruwa sosai.
It was in Kano that it rained heavily.
Key Takeaways
- Weather nouns can be ordinary subjects: iska tana..., ruwa yana..., rana ta....
- Ana ruwa presents ongoing rain impersonally; an yi ruwa presents a bounded rain event.
- Yi predicates conditions such as heat or darkness, while akwai/babu assert presence or absence.
- Hausa does not use a dummy pronoun equivalent to English weather it.
- Locative focus requires ne and relative TAM: A Kano ne aka yi ruwa.
