Ka in Hindi — का, की, के | Meaning, Usage & Grammar Rules

का (ka) is a Hindi postposition that indicates possession, ownership, or relation between two nouns. It is equivalent to:

• "of" in English — "the book of Ram" = "राम की किताब" • "'s" (apostrophe s) in English — "Ram's house" = "राम का घर"

Unlike English prepositions that come before a noun, Hindi postpositions come after the noun. That is why "of" comes before a noun in English, but का comes after the noun in Hindi: • English: House of Ram → Hindi: राम का घर (Ram ka ghar)

का is part of the संबंध कारक (sambandh karak — possessive case) in Hindi grammar. It connects two nouns to show that one belongs to or is related to the other.

The postposition का changes form based on the gender and number of the noun that follows it (the thing being possessed, not the possessor):

1. का (ka) — used when the following noun is masculine singular • राम का घर (Ram ka ghar) — Ram's house (घर is masculine singular) • लड़के का नाम (ladke ka naam) — the boy's name (नाम is masculine singular) • पिता का प्यार (pita ka pyaar) — father's love (प्यार is masculine singular)

2. की (ki) — used when the following noun is feminine (singular or plural) • सीता की किताब (Seeta ki kitaab) — Sita's book (किताब is feminine) • राम की बहन (Ram ki bahan) — Ram's sister (बहन is feminine) • लड़की की सहेलियाँ (ladki ki saheliyan) — the girl's friends (सहेलियाँ is feminine plural)

3. के (ke) — used when the following noun is masculine plural, or masculine singular in oblique case • राम के भाई (Ram ke bhai) — Ram's brothers (भाई is masculine plural) • लड़कों के खेल (ladkon ke khel) — the boys' games (खेल is masculine plural) • राम के घर में (Ram ke ghar mein) — in Ram's house (घर is in oblique case because of में)

The key rule is simple: look at the noun AFTER का/की/के (the possessed noun) to decide which form to use.

Rule 1: If the next noun is masculine singular (direct case) → use का • मोहन का बेटा (Mohan ka beta) — Mohan's son • देश का नाम (desh ka naam) — the country's name

Rule 2: If the next noun is feminine (singular or plural) → use की • मोहन की बेटी (Mohan ki beti) — Mohan's daughter • देश की राजधानी (desh ki rajdhani) — the country's capital • मोहन की बेटियाँ (Mohan ki betiyan) — Mohan's daughters

Rule 3: If the next noun is masculine plural, or masculine singular in oblique case → use के • मोहन के बेटे (Mohan ke bete) — Mohan's sons • मोहन के बेटे को (Mohan ke bete ko) — to Mohan's son (oblique case)

Common mistake: Do NOT look at the possessor (the noun before का/की/के). It does not matter whether the possessor is masculine or feminine. Only the noun after का/की/के determines the form. • सीता का घर (Seeta ka ghar) — Sita's house (का because घर is masculine, even though सीता is feminine) • राम की किताब (Ram ki kitaab) — Ram's book (की because किताब is feminine, even though राम is masculine)

In Hindi grammar, there are 8 types of कारक (karak — cases). का/की/के belong to the 6th case called संबंध कारक (sambandh karak — possessive/genitive case).

The 8 karak and their vibhakti (case markers):

1. कर्ता कारक (Karta) — ने
2. कर्म कारक (Karma) — को
3. करण कारक (Karaṇ) — से, द्वारा
4. संप्रदान कारक (Sampradan) — को, के लिए
5. अपादान कारक (Apadan) — से (separation)
6. संबंध कारक (Sambandh) — का, की, के
7. अधिकरण कारक (Adhikaran) — में, पर
8. संबोधन कारक (Sambodhan) — हे, अरे

संबंध कारक shows the relationship or possession between two nouns. The vibhakti (case markers) for this case are का, की, के.

Apart from being a postposition, "ka" is also the first consonant in the Hindi alphabet.

• क (ka) is the first letter of the क वर्ग (ka varg) group in the Hindi Varnamala • It is a Sparsh Vyanjan (touch consonant) — produced from the throat (कंठ) • It is Aghosh (unvoiced) and Alpapran (unaspirated) • The क वर्ग group: क (ka), ख (kha), ग (ga), घ (gha), ङ (nga)

Note: क (the letter) and का (the postposition) are different. क is a consonant letter, while का is a grammatical word showing possession.
