Hindi uses adjectives from Persian, Arabic, Sanskrit, and—especially in contemporary urban and professional speech—English. Most recent loans and many older Perso-Arabic adjectives are indeclinable: स्मार्ट लड़का, स्मार्ट लड़की, स्मार्ट बच्चे, and स्मार्ट लड़कियाँ all keep स्मार्ट unchanged.
Borrowed origin, however, is not a grammatical rule. Some long-integrated loans have entered a Hindi declension, such as बेचारा → बेचारे/बेचारी. The reliable distinction is therefore morphological: learn whether a word has an agreement paradigm, not merely where it came from.
The broader indeclinable-adjective pattern applies equally to inherited vocabulary and loans; this page concentrates on the extra uncertainty created by borrowing and integration.
The typical invariant pattern
The contemporary English loan स्मार्ट smārṭ illustrates the common pattern.
| Noun features | Noun phrase |
|---|---|
| masculine singular direct | स्मार्ट लड़का smārṭ laṛkā |
| masculine plural direct | स्मार्ट लड़के smārṭ laṛke |
| masculine singular oblique | स्मार्ट लड़के से smārṭ laṛke se |
| masculine plural oblique | स्मार्ट लड़कों से smārṭ laṛkoṃ se |
| feminine singular direct | स्मार्ट लड़की smārṭ laṛkī |
| feminine plural oblique | स्मार्ट लड़कियों से smārṭ laṛkiyoṃ se |
The nouns show number and case; the adjective does not.
नई इंटर्न बहुत स्मार्ट है और जल्दी सीखती है।
naī iṇṭarn bahut smārṭ hai aur jaldī sīkhtī hai.
The new intern is very sharp and learns quickly. (everyday professional Hindi)
स्मार्ट बच्चों को भी स्पष्ट निर्देश चाहिए।
smārṭ baccoṃ ko bhī spaṣṭ nirdeś cāhie.
Even bright children need clear instructions.
मैं उस स्मार्ट लड़के से पहले मिल चुका हूँ।
maĩ us smārṭ laṛke se pahle mil cukā hū̃.
I have met that smart boy before. (male speaker)
Established Perso-Arabic adjectives
Many extremely ordinary Hindi adjectives of Persian or Arabic origin are invariant. They are not necessarily marked or bookish.
| Adjective | Meaning | Typical register |
|---|---|---|
| ख़ास xās | special | neutral |
| मशहूर maśhūr | famous | neutral |
| ज़रूरी zarūrī | necessary | neutral |
| आसान āsān | easy | neutral |
| दिलचस्प dilcasp | interesting | neutral |
| बेकार bekār | useless; unemployed | neutral, meaning depends on context |
उस मशहूर गायिका का नया गाना आज जारी हुआ।
us maśhūr gāyikā kā nayā gānā āj jārī huā.
That famous singer's new song was released today.
ये निर्देश छोटे हैं, लेकिन बहुत ज़रूरी हैं।
ye nirdeś choṭe haiṃ, lekin bahut zarūrī haiṃ.
These instructions are short but very important.
In the first example, invariant मशहूर modifies feminine oblique गायिका. In the second, declinable छोटे visibly agrees with masculine plural निर्देश, while invariant ज़रूरी does not. Their descriptive force is equally complete.
Contemporary English loans
Words such as फ़िट, मॉडर्न, डिजिटल, ऑनलाइन, प्रैक्टिकल, पॉपुलर, and सीरियस normally remain invariant when used as Hindi adjectives. These are common in urban, media, technology, and workplace contexts (informal/professional), but their frequency varies by speaker and setting. Formal writing may prefer established Hindi alternatives such as व्यावहारिक for प्रैक्टिकल; both are indeclinable.
चारों डिजिटल फ़ाइलों को अलग फ़ोल्डर में रखिए।
cāroṃ ḍijiṭal fāiloṃ ko alag folḍar meṃ rakhie.
Please put all four digital files in a separate folder. (professional/respectful)
यह योजना सुनने में अच्छी है, लेकिन क्या यह प्रैक्टिकल है?
yah yojnā sunne meṃ acchī hai, lekin kyā yah praikṭikal hai?
This plan sounds good, but is it practical? (informal professional Hindi)
ये जूते अभी भी फ़िट हैं, इसलिए नए मत ख़रीदो।
ye jūte abhī bhī fiṭ haiṃ, islie nae mat xarīdo.
These shoes still fit, so don't buy new ones. (informal)
Using a loan does not suspend Hindi syntax. Adjectives remain normally prenominal when attributive, postpositions still assign oblique case, and verbs and auxiliaries still agree according to Hindi rules.
Attributive and predicative use
Loan adjectives can appear before nouns or as predicates without changing form.
हमें मॉडर्न डिज़ाइन चाहिए, लेकिन यह डिज़ाइन बहुत महँगा है।
hameṃ moḍarn ḍizāin cāhie, lekin yah ḍizāin bahut mahãgā hai.
We want a modern design, but this design is very expensive.
मॉडर्न is invariant and attributive. Predicative महँगा belongs to the declinable class and agrees with masculine डिज़ाइन. The contrast demonstrates morphology, not a difference between “real” and “less real” adjectives.
दोनों विकल्प पॉपुलर हैं, पर दूसरा थोड़ा सस्ता है।
donoṃ vikalp popyular haiṃ, par dūsrā thoṛā sastā hai.
Both options are popular, but the second is a little cheaper. (informal)
Degree is analytic: बहुत पॉपुलर, ज़्यादा प्रैक्टिकल, सबसे मशहूर. The loan does not acquire English comparative -er or Hindi agreement morphology.
Borrowed but declinable: an important exception
Some established loans have been reshaped as Hindi -आ adjectives. Persian-derived बेचारा becārā “poor, unfortunate” has the regular forms बेचारा, बेचारे, बेचारी in educated Standard Hindi.
बेचारा बच्चा रास्ता भूल गया था, और बेचारी बच्ची रो रही थी।
becārā baccā rāstā bhūl gayā thā, aur becārī baccī ro rahī thī.
The poor boy had lost his way, and the poor girl was crying.
बेचारे यात्रियों को कई घंटे इंतज़ार करना पड़ा।
becāre yātriyoṃ ko kaī ghaṇṭe intazār karnā paṛā.
The unfortunate travelers had to wait for several hours.
Origin cannot predict this integration. Final -आ does not prove that a loan declines either: ताज़ा is often invariant in combinations such as ताज़ा ख़बर, alongside widespread inflected forms such as ताज़ी हवा and ताज़े फल. Learn actual forms and collocations rather than forcing a paradigm from spelling alone.
Conventional meanings of loans
Loans often develop Hindi-specific collocations. स्मार्ट छात्र can mean clever or polished, while स्मार्ट फ़ोन is a lexicalized technology term. फ़िट can describe physical fitness, clothing that fits, or suitability in a role. Meaning changes with the noun, but the adjective remains morphologically fixed.
वह इस भूमिका के लिए बिल्कुल फ़िट है।
vah is bhūmikā ke lie bilkul fiṭ hai.
She is exactly right for this role.
Agreement in a perfective ने-clause
An invariant loan adjective does not cause default agreement and does not agree with the agent. Other agreeing elements still follow the ordinary controller.
सोनल ने स्मार्ट घड़ी ख़रीदी।
sonal ne smārṭ ghaṛī xarīdī.
Sonal bought a smart watch.
स्मार्ट stays fixed; feminine ख़रीदी agrees with unmarked feminine घड़ी, not with the ने-marked agent.
Common Mistakes
❌ उसने डिजिटलें फ़ाइलें भेजीं।
Incorrect—डिजिटल is invariant; plural belongs on फ़ाइलें, not on the adjective.
✅ उसने डिजिटल फ़ाइलें भेजीं।
usne ḍijiṭal fāileṃ bhejīṃ.
She sent digital files.
❌ वह बहुत स्मार्टी लड़की है।
Incorrect—स्मार्टी is not the feminine agreement form of adjectival स्मार्ट.
✅ वह बहुत स्मार्ट लड़की है।
vah bahut smārṭ laṛkī hai.
She is a very smart girl.
❌ वह बेचारा लड़की घंटों इंतज़ार करती रही।
Incorrect—declinable बेचारा must take feminine बेचारी with लड़की.
✅ वह बेचारी लड़की घंटों इंतज़ार करती रही।
vah becārī laṛkī ghaṇṭoṃ intazār kartī rahī.
The poor girl kept waiting for hours.
❌ मीना ने स्मार्ट घड़ी ख़रीदा।
Incorrect—the invariant adjective is fine, but the perfective must agree with unmarked feminine घड़ी.
✅ मीना ने स्मार्ट घड़ी ख़रीदी।
mīnā ne smārṭ ghaṛī xarīdī.
Meena bought a smart watch.
Key Takeaways
- Most recent loans and many established Perso-Arabic adjectives are indeclinable.
- Borrowing does not guarantee invariability: integrated बेचारा has a regular -आ/-ए/-ई paradigm.
- Loan adjectives work attributively and predicatively, and combine with Hindi degree words without changing form.
- Invariability belongs only to the adjective; nouns, verbs, and auxiliaries continue to mark Hindi grammar.
- Register varies: English loans are especially frequent in informal, technical, and professional settings, while many Perso-Arabic loans are fully neutral.
