Equality with kai and kamar | Hausa Grammar

English packages equality inside the frame as + adjective + as. Hausa does not need two copies of an “as” word. For exact equality on a named scale, it commonly uses the stative verb kai “reach, equal”: Musa ya kai Ali tsawo “Musa is as tall as Ali.” For resemblance or a comparison understood from context, kamar “like, as” is often more natural.

All unlabelled examples are (neutral Nigerian Standard Hausa). The crucial choice is semantic: kai asserts that one referent reaches the standard on a scale, whereas kamar presents one description as similar to another. In ordinary conversation kamar can communicate practical equality, but it is not a mathematical equality marker by itself.

For the corresponding “more than” construction, see Comparatives with fi.

Kai builds a measured equative

The basic pattern is:

subject + completive subject marker + kai + standard + property noun

Musa ya kai Ali tsawo.

Musa is as tall as Ali.

Amina ta kai Zainab tsawo.

Amina is as tall as Zainab.

Waɗannan igiyoyin sun kai juna tsawo.

These ropes are equal in length.

The subject marker agrees with the item being assessed: masculine singular ya, feminine singular ta, and plural sun. The standard follows kai, and the scale follows the standard: Ali tsawo “Ali in height.” English makes tall look like the grammatical center; Hausa uses the verb kai and the quality noun tsawo “height/length.”

Subject	Agreement	Equative clause
masculine singular	ya	Musa ya kai Ali tsawo.
feminine singular	ta	Amina ta kai Zainab tsawo.
plural	sun	Igiyoyin sun kai juna tsawo.

Kai is stative in this use, so the completive forms are the ordinary choice even for a present comparison. Do not replace ya/ta/sun with English-style present forms merely because the translation contains is/are.

Wannan tankin ya kai wancan girma, amma bai kai shi zurfi ba.

This tank is as large as that one, but it is not as deep.

Sabuwar igiyar ta kai tsohuwar ƙarfi.

The new rope is as strong as the old one.

💡

With kai, name the scale as a Hausa noun: tsawo “height/length,” ƙarfi “strength,” girma “size,” or sauri “speed.” Do not try to insert an agreeing adjective into the verbal frame.

Pronoun standards are object forms

When the standard is a pronoun, use the direct-object form after kai. Thus ni means “me,” ka “you (masculine singular),” ki “you (feminine singular),” and shi/ta/mu/ku/su “him/her/us/you plural/them.”

Ka kai ni tsawo, amma na fi ka nauyi.

You are as tall as me, but I am heavier than you. (to one male)

Kin kai ni sauri; mu yi tseren tare.

You are as fast as me; let us race together. (to one female)

Ban kai su ƙarfi ba, amma ina da haƙuri.

I am not as strong as they are, but I am patient.

The last sentence shows the negative ban kai ... ba, literally “I do not equal ...,” which is also the ordinary basis of an inferiority comparison. Equality and “less than” are therefore grammatically connected in Hausa in a way that English hides.

Kamar presents similarity

Kamar introduces a model, comparison, or likeness. It can follow several kinds of property predicate because Hausa property concepts belong to several word classes.

Musa dogo ne kamar mahaifinsa.

Musa is tall like his father.

Aisha tana da haƙuri kamar uwarta.

Aisha is patient like her mother.

Waɗannan ɗakunan suna da faɗi kamar babban zauren.

These rooms are spacious like the main hall.

In the first sentence, dogo ne is a true-adjective predicate. In the second and third, haƙuri and faɗi are quality nouns inside yana/tana/suna da constructions. Kamar itself does not agree with masculine, feminine, or plural subjects; the adjective, copula, or subject marker elsewhere in the clause carries the agreement.

The comparison with kamar need not claim identical degree. Musa dogo ne kamar mahaifinsa may mean that both count as tall, or that Musa resembles his father in height. If a measurement or careful judgment requires equality, Musa ya kai mahaifinsa tsawo is more exact.

Sabuwar motar tana da ƙarfi kamar tsohuwar, amma tana cin mai kaɗan.

The new car is powerful like the old one, but it uses less fuel.

💡

Use kai + standard + scale when “equal on this dimension” matters. Use kamar + noun phrase when “like/similar to” is enough.

Attributive and predicative equality

An attributive expression belongs inside a noun phrase. A predicative expression makes a full claim. With quality nouns, the contrast is especially clear:

Mun ɗauki yaro mai tsawo kamar mahaifinsa.

We hired a boy as tall as his father.

Yaron yana da tsawo kamar mahaifinsa.

The boy is tall like his father.

Muna neman ma’aikata masu haƙuri kamar shugabarsu.

We are looking for workers who are as patient as their supervisor.

Singular attributive mai tsawo works with either masculine or feminine heads; plural heads take masu tsawo. Predicative possession agrees as yana da, tana da, or suna da. Do not force an invented masculine/feminine ending onto the invariant noun tsawo or haƙuri.

A true adjective uses its own agreement set:

Yaron dogo ne kamar kawunsa.

The boy is tall like his uncle.

Yarinyar doguwa ce kamar yayarta.

The girl is tall like her older sister.

Yaran dogaye ne kamar iyayensu.

The children are tall like their parents.

Here dogo/doguwa/dogaye and ne/ce/ne agree. Kamar remains unchanged. This is why equality is not a special adjective ending: the comparison phrase is added to a property construction that must already be well formed.

A contextual judgment

A ganina, wannan ɗakin ya kai wancan faɗi, amma bai kai shi haske ba.

In my view, this room is as spacious as that one, but it is not as bright.

The speaker explicitly equates the rooms on faɗi “spaciousness” and denies equality on haske “brightness.” A looser version with kamar—Wannan ɗakin yana da faɗi kamar wancan—would describe a resemblance rather than foregrounding two separately judged scales.

Practice

Choose kai for exact equality and kamar for likeness.

Agogon nan ya kai wancan tsada.

This watch is as expensive as that one.

Muryarta tana da daɗi kamar ta mahaifiyarta.

Her voice is pleasant like her mother's.

Kujerun biyu sun kai juna girma.

The two chairs are the same size.

Common Mistakes

1. Copying the English double-as frame

❌ Musa as dogo as Ali.

Incorrect — Hausa does not insert English as around an adjective.

✅ Musa ya kai Ali tsawo a yanzu.

Musa is now as tall as Ali.

2. Putting an agreeing adjective where kai requires a scale noun

❌ Amina ta kai Zainab doguwa.

Incorrect — use the quality noun tsawo after the standard.

✅ Amina ta kai ƙawarta tsawo.

Amina is as tall as her friend.

3. Making kamar agree

❌ Yarinyar doguwa ce kamarta yayarta.

Incorrect — kamar does not take feminine agreement before the standard.

✅ Yarinyar nan doguwa ce kamar yayarta.

This girl is tall like her older sister.

4. Using masculine adjective agreement for every subject

❌ Yaran dogo ne kamar mahaifinsu.

Incorrect — a plural subject requires dogaye.

✅ Yaran dogaye ne kamar mahaifinsu.

The children are tall like their father.

Key Takeaways

Kai is a stative verb: subject + completive marker + kai
- standard + property noun.
Kamar expresses likeness and can imply practical equality, but it does not inherently assert an exact match.
Pronouns after kai are object forms: ni, ka, ki, shi, ta, mu, ku, su.
Agreement stays in the underlying property construction; kamar is invariant.
Hausa compares tsawo, ƙarfi, girma, and other scales as nouns rather than copying English as + adjective + as.
