कई kaī means “several,” “a number of,” or sometimes “many.” It quantifies countable plural referents and remains invariant. The following noun and predicate carry number and case: कई बच्चे आए, कई बच्चों से मिला. Unlike an exact numeral, कई leaves the number open while asserting more than one.
Form and position
| Environment | Phrase |
|---|---|
| direct plural | कई बच्चे kaī bacce |
| oblique plural | कई बच्चों को kaī baccoṃ ko |
| feminine plural | कई किताबें kaī kitābeṃ |
| with adjective | कई पुराने घर kaī purāne ghar |
कई यात्री ट्रेन छूटने से पहले स्टेशन पहुँच गए।
kaī yātrī ṭren chūṭne se pahle sṭeśan pahũc gae.
Several passengers reached the station before the train left.
मैंने कई पुरानी तस्वीरें सँभालकर रखी हैं।
maĩne kaī purānī tasvīreṃ sãbhālkar rakhī haiṃ.
I have carefully kept several old photographs.
कई does not agree. Masculine plural पुराने घर and feminine plural पुरानी तस्वीरें show agreement elsewhere in the phrase.
कई versus कुछ
Both can introduce an indefinite subset. कई emphasizes multiplicity—several distinct members. कुछ is more neutral and also works with mass nouns.
The count–mass contrast is developed under कुछ “some/any”.
कुछ लोगों ने सवाल पूछे, और कई लोगों ने लिखित सुझाव दिए।
kuch logoṃ ne savāl pūche, aur kaī logoṃ ne likhit sujhāv die.
Some people asked questions, and several people gave written suggestions.
With पानी, use कुछ पानी, not कई पानी, because unmeasured water is mass. A count unit licenses कई गिलास पानी “several glasses of water.” Hindi uses an ordinary measure noun, not a general obligatory classifier.
कई versus बहुत and exact numbers
बहुत से लोग often suggests “many people,” a larger or more evaluative quantity. कई लोग is compatible with “several” and can also be rhetorically strong, but it does not inherently mean “a great many.” Exact numbers answer precisely.
बैठक में कई लोग आए, लेकिन अपेक्षा से बहुत कम लोग थे।
baiṭhak meṃ kaī log āe, lekin apekṣā se bahut kam log the.
Several people came to the meeting, but there were far fewer people than expected.
उसने कई बार फ़ोन किया—ठीक पाँच बार।
usne kaī bār fon kiyā—ṭhīk pā̃c bār.
He or she called several times—exactly five times.
The second clause replaces an approximate plural with an exact count. Full numeral formation belongs to Numbers and Measurement.
Definiteness and partitives
Bare कई छात्र introduces an indefinite plural. A demonstrative or partitive frame identifies the domain: इन छात्रों में से कई “several of these students.”
इन प्रस्तावों में से कई व्यावहारिक हैं।
in prastāvoṃ meṃ se kaī vyāvahārik haiṃ.
Several of these proposals are practical.
Here the proposals are definite through इन, while कई selects an indefinite-sized subset. Hindi needs no article.
The quantifier can stand alone when its noun is recoverable:
आवेदन बहुत आए थे, लेकिन कई अधूरे थे।
āvedan bahut āe the, lekin kaī adhūre the.
Many applications had arrived, but several were incomplete.
Standalone कई inherits semantic class and agreement from the omitted noun; it does not itself encode gender. Masculine plural अधूरे helps recover आवेदन here. With feminine फ़ाइलें, one would say कई अधूरी थीं. Ellipsis is natural only when the missing noun is already salient.
Repeated कई-कई can have a distributive “several each” reading. It is not merely a stronger synonym of बहुत: reduplication distributes multiple items across participants or occasions, and the surrounding clause must support that interpretation.
Singular and plural
कई normally requires plural semantic reference. A following class-II masculine noun may look unchanged: कई सवाल, कई होटल. Its oblique plural becomes visible before a postposition.
This hidden direct-plural pattern is morphological, not evidence that कई can quantify an ordinary singular count noun.
कई सवालों के जवाब रिपोर्ट में मिल जाएँगे।
kaī savāloṃ ke javāb riporṭ meṃ mil jāẽge.
The answers to several questions will be found in the report.
For one nonspecific member use कोई सवाल or एक सवाल, not कई सवाल with singular agreement.
Scope
हर शिक्षक ने कई छात्रों से बात की।
har śikṣak ne kaī chātroṃ se bāt kī.
Every teacher spoke with several students. (normally potentially different students per teacher)
The common reading places कई within हर: each teacher has a possibly different group. वही कई छात्र or an explicit named group can produce a shared-set reading.
Common Mistakes

Incorrect—कई requires plural reference and agreement.
✅ कई बच्चे बाहर खेल रहे हैं।
kaī bacce bāhar khel rahe haiṃ.
Several children are playing outside.

Incorrect—unmeasured दूध is a mass noun.

Incorrect—plural छात्र must be oblique plural before से.
✅ मैंने कई छात्रों से बात की।
maĩne kaī chātroṃ se bāt kī.
I spoke with several students.
❌ कई हर छात्र आया।

kaī chātr āe, lekin har chātr samay par nahīṃ āyā.
Several students came, but not every student arrived on time.
Key Takeaways
- कई is invariant but selects plural count reference.
- Use कुछ for mass quantity or a neutral subset and बहुत for a strongly large quantity.
- Direct plural may be invisible on some nouns; oblique plural and predicate agreement expose it.
- Demonstratives can define a definite domain: इनमें से कई.
- Quantifier scope may allow a different several-member set for each distributor.
