एक ek has two central uses. As a numeral it means exactly “one,” contrasting with two or more. As an indefinite or presentational marker it introduces one new countable referent: एक आदमी आया ek ādmī āyā “a man came.” These uses overlap because introducing “a man” still presents a single individual.
Hindi nevertheless has no indefinite article. एक is optional in many places where English requires a/an, and it often adds individuation, narrative prominence, or the sense “a certain.” Treating every English a as एक produces heavy, unnatural Hindi.
एक as the exact numeral “one”
When quantity is contrasted or counted, एक is a numeral. It is invariant: it does not change for gender or case.
मुझे दो टिकट नहीं, सिर्फ़ एक टिकट चाहिए।
mujhe do ṭikaṭ nahīṃ, sirf ek ṭikaṭ cāhie.
I don't need two tickets; I need only one ticket.
हम एक दिन दिल्ली में और तीन दिन जयपुर में रहेंगे।
ham ek din dillī meṃ aur tīn din jaypur meṃ raheṅge.
We will stay one day in Delhi and three days in Jaipur.
Focus words make exact cardinality unmistakable: सिर्फ़ एक “only one,” केवल एक (formal), एक ही “one and the same/only one,” and ठीक एक “exactly one.”
एक introducing a new referent
Stories and explanations often use एक + singular noun to place a new participant into the discourse. Once established, the noun can appear bare or as a pronoun.
एक महिला रिसेप्शन पर आई। महिला ने अपना नाम नंदिता बताया।
ek mahilā risepśan par āī. mahilā ne apnā nām nanditā batāyā.
A woman came to reception. The woman said that her name was Nandita.
रास्ते में एक छोटा-सा कैफ़े मिला; हमने वहीं चाय पी।
rāste meṃ ek choṭā-sā kaife milā; hamne vahīṃ cāy pī.
We found a little café on the way; we had tea there.
The first mention is indefinite. The second reference is definite through discourse: bare महिला and locative वहीं point back to what has already been introduced. Hindi does not insert a word meaning the.
एक can also suggest “a certain,” especially when the speaker withholds or delays identification:
आपसे एक व्यक्ति मिलने आया है, लेकिन उसने अपना नाम नहीं बताया।
āpse ek vyakti milne āyā hai, lekin usne apnā nām nahīṃ batāyā.
A certain person has come to meet you, but he did not give his name. (respectful)
Why एक is not an article
Bare singular count nouns readily introduce new referents. Predicate professions, roles, and types are especially natural without एक.
हमें कमरा चाहिए था; पास में होटल मिल गया।
hameṃ kamrā cāhie thā; pās meṃ hoṭal mil gayā.
We needed a room; we found a hotel nearby.
निखिल इंजीनियर है और उसकी पत्नी वकील है।
nikhil iñjīniyar hai aur uskī patnī vakīl hai.
Nikhil is an engineer, and his wife is a lawyer.
Adding एक is possible when “one/a certain” matters: एक इंजीनियर ने यह डिज़ाइन बनाया “an engineer designed this.” But neutral classification uses bare इंजीनियर है. The broader zero-article system is explained on no articles in Hindi.
Mass nouns also resist bare एक unless a countable unit is understood. एक चाय can mean “one tea” in a café order (informal), with “cup/order” supplied by context; ordinary “some tea” is थोड़ी चाय.
Position and agreement inside the noun phrase
एक normally precedes adjectives and the noun: एक अच्छा विचार, एक नई योजना. The numeral remains unchanged, while a declinable adjective agrees with the noun.
| Phrase | Agreement |
|---|---|
| एक अच्छा लड़का ek acchā laṛkā | masculine singular direct |
| एक अच्छी लड़की ek acchī laṛkī | feminine |
| एक अच्छे लड़के को ek acche laṛke ko | masculine singular oblique |
मैंने एक अच्छे कारीगर को बुलाया है।
maĩne ek acche kārīgar ko bulāyā hai.
I have called a good craftsperson.
The noun phrase is oblique before को, so अच्छा → अच्छे. एक has no agreeing form. Hindi normally places a numeral directly before its noun phrase; there is no general classifier between एक and कारीगर.
Singular and plural indefinites
एक individuates one countable entity, so it does not directly modify an ordinary plural noun. Indefinite plurals may be bare or use कुछ “some” and कई “several.”
बाहर एक छात्र इंतज़ार कर रहा है और अंदर कुछ छात्र बैठे हैं।
bāhar ek chātr intazār kar rahā hai aur andar kuch chātr baiṭhe haiṃ.
One student is waiting outside, and some students are sitting inside.
The form छात्र is invariant in the direct plural, but plural बैठे हैं and कुछ establish the plural reading. एक छात्र is singular.
Paired indefinite and definite readings
मुझे मेज़ पर एक लिफ़ाफ़ा मिला। लिफ़ाफ़े पर आपका नाम लिखा था।
mujhe mez par ek lifāfā milā. lifāfe par āpkā nām likhā thā.
I found an envelope on the table. Your name was written on the envelope.
First-mention एक लिफ़ाफ़ा introduces the envelope. Second-mention लिफ़ाफ़े पर is identifiable and oblique before पर. There is still no definite article.
A demonstrative can make contrast explicit:
वह लिफ़ाफ़ा मेरा नहीं है; मुझे दूसरा लिफ़ाफ़ा मिला था।
vah lifāfā merā nahīṃ hai; mujhe dūsrā lifāfā milā thā.
That envelope is not mine; I found a different envelope.
Scope with हर and negation
हर छात्र ने एक लेख पढ़ा।
har chātr ne ek lekh paṛhā.
Every student read an article. (possibly different articles, or one contextually shared article)
The most accessible reading allows a different article per student: हर > एक. Context can instead make एक wide-scope, one article shared by all. Use एक ही लेख for “one and the same article” and अलग-अलग लेख for different articles.
Negation creates another scope contrast:
एक भी छात्र देर से नहीं आया।
ek bhī chātr der se nahīṃ āyā.
Not a single student arrived late.
एक भी under negation means “even one/not a single,” not the indefinite article a. Scope is carried by the combination एक भी... नहीं.
Each, every, some, and any require their own forms
एक does not mean “each” or “every”; use हर or formal प्रत्येक. It does not generally mean plural “some”; use कुछ or कई. Indefinite/free-choice “any” may require कोई, किसी, or किसी भी, according to syntax and meaning.
हर मेहमान को एक कप चाय दीजिए।
har mehmān ko ek kap cāy dījie.
Give each guest one cup of tea. (respectful command)
Here हर distributes over guests, while एक counts cups. Translating both English determiners with the same word would erase the structure.
Common Mistakes
Combining एक with a plural noun
❌ एक किताबें मेज़ पर हैं।
Incorrect—एक requires one countable referent, not plural किताबें.
✅ एक किताब मेज़ पर है।
ek kitāb mez par hai.
A book is on the table.
Giving the adjective the wrong agreement
❌ एक नई कमरा खाली है।
Incorrect—masculine कमरा requires नया.
✅ एक नया कमरा खाली है।
ek nayā kamrā khālī hai.
A new room is vacant.
Using एक for “every”
❌ एक बच्चा को टीका लगना चाहिए।
Incorrect for a general rule about every child; the noun phrase also has the wrong case form before को.
✅ हर बच्चे को टीका लगना चाहिए।
har bacce ko ṭīkā lagnā cāhie.
Every child should be vaccinated.
Using count singular with a mass reading
❌ उसने एक दूध खरीदा।
Incorrect for ordinary milk quantity—no countable unit is expressed.
✅ उसने थोड़ा दूध खरीदा।
usne thoṛā dūdh kharīdā.
He or she bought some milk.
Key Takeaways
- एक is exactly “one” when quantity is counted or contrasted.
- It can introduce a new singular referent and sometimes means “a certain,” but it is not obligatory.
- Bare nouns are normal in professions, classifications, mass readings, and many indefinite introductions.
- एक is invariant; adjectives and nouns still show their own gender and case morphology.
- Use distinct quantifiers for each/every, some, and any, and watch their scope.
