शब्द-भेद (Shabd Bhed) is Hindi grammar's way of sorting every word you encounter into a meaningful category — exactly the way a post office sorts letters by destination. Just as you wouldn't mix a money order with a postcard, Hindi grammar doesn't treat a verb the same as a noun, or a Sanskrit-origin word the same as an Arabic one.
In Hindi grammar, शब्द-भेद covers two major axes of classification:
Axis 1 — Origin (उत्पत्ति के आधार पर): Where did this word come from? Sanskrit? A modified form of Sanskrit? A regional dialect? A foreign language like Persian or English?
Axis 2 — Function (व्याकरणिक कार्य के आधार पर): What does this word do in a sentence? Does it name something (संज्ञा)? Replace a name (सर्वनाम)? Describe something (विशेषण)? Show action (क्रिया)?
Think of it like a city's population register. Every resident is classified by their origin (native, migrated, foreign-national) and by their profession (teacher, trader, farmer). शब्द-भेद does exactly this for Hindi words.
For UP Police Constable, the questions almost always target:
You don't need to memorize every theoretical category. You need to recognize patterns quickly and eliminate wrong options with confidence.
This is the most tested area in UP Police Constable Hindi. Four types exist:
The word "तत्सम" itself tells you: तत् (that) + सम (same) — words that remain unchanged from Sanskrit. These are formal, literary words used in writing and official language.
Recognition pattern: If a word ends in -इह, -अन्, -त्व, -य or has a conjunct consonant cluster typical of Sanskrit (like क्ष, ज्ञ, श्र, त्र), it is likely तत्सम.
Examples: कार्य, कर्म, मातृ, राजन्, गमिह, अग्नि, वायु, क्षेत्र
तद् (that/Sanskrit) + भव (born from) — these are words that started as Sanskrit but changed their pronunciation and spelling over centuries of common use. They are the everyday spoken forms.
| तत्सम | तद्भव | |-------|-------| | अग्नि | आग | | कर्म | काम | | दुग्ध | दूध | | हस्त | हाथ | | नयन | नैन |
Recognition pattern: If you can trace a word back to a Sanskrit root but the spelling is "simplified" (no conjuncts, shorter vowels), it is तद्भव.
Key exam fact: तद्भव words are formed from Sanskrit words with phonetic changes — this is exactly what the 2018 PYQ asked.
Words that originated from local dialects (Awadhi, Braj, Bhojpuri) with no clear Sanskrit ancestry. These are folk words.
Examples: पगड़ी, लोटा, खिड़की, थैला, चिड़िया, डिब्बा
Recognition: If the word feels rustic or regional and has no obvious Sanskrit counterpart, it is likely देशज.
Words borrowed from foreign languages — Persian/Urdu (फारसी), Arabic (अरबी), English (अंग्रेजी), Portuguese (पुर्तगाली), etc.
Common विदेशज words:
Names of persons, places, things, qualities, or states. UP Police Constable tests two grammar points intensively under संज्ञा:
वचन (Vachan / Number): Singular (एकवचन) → Plural (बहुवचन)
Rules you must know:
लिंग (Ling / Gender): Masculine (पुल्लिंग) → Feminine (स्त्रीलिंग)
Key suffix patterns for स्त्रीलिंग:
This is tested directly in UP Police Constable. A phrase is given — you choose the single word that means the same.
The logic is almost always prefix-based:
If you know the prefix meanings, you can decode most one-word substitutions without having memorized the exact compound word.
Look for conjunct consonants (संयुक्त व्यंजन) — clusters like क्ष, ज्ञ, श्र, त्र, द्ध, न्द. If a word has one, it is almost certainly तत्सम. If you see the same meaning in a simpler form (no clusters), that simpler form is तद्भव. Example: क्षेत्र (तत्सम) → खेत (तद्भव). This eliminates wrong options in 8-10 seconds vs. trying to recall origin from memory (30+ seconds).
When a question asks which suffix forms बहुवचन for respected or collective persons: गण is for respected collectives (देवगण, सुधिगण, श्रोतागण), वृन्द is literary and rare, वर्ग is for categories/classes (not persons), जन is for common people (जनगण, नागरिकजन). In most questions, गण wins for dignified human/divine groups. Identifying this takes 5 seconds vs. reading all four options carefully (20+ seconds).
When the phrase contains "जिसका कोई X न हो" (without X), the answer almost always starts with नि or निर. When the phrase contains "सरलता से / आसानी से" (easily/with ease), the answer starts with सु. Apply the prefix test first, before reading all options. This narrows four options to one in under 10 seconds vs. matching each option to the phrase individually (25-35 seconds).
For community/caste/title nouns (राजपूत, देवर, जेठ), the feminine almost always uses -आनी: राजपूतानी, देवरानी, जेठानी. Wrong options typically offer -ई (राजपूती — this is an adjective, not a feminine noun), -इन (for occupational nouns like धोबिन, मालिन), or -रीन (not a standard suffix). Eliminating -ई and -इन options immediately leaves you with the correct -आनी form. Step count: 2 eliminations vs. recalling the form cold (4-5 steps).
Any feminine noun ending in -ई forms its plural with -इयाँ: मिठाई → मिठाइयाँ, लड़की → लड़कियाँ, टोकरी → टोकरियाँ. Any option offering a form like "मिठाई" itself (unchanged) or "मिठाईएँ" is wrong. Recognizing this pattern takes 3 seconds — standard recall without the rule takes 15-20 seconds.
When you see a Hindi शब्द-भेद question in the exam hall, run through this decision tree:
Step 1 — Identify the question type:
Step 2 — Eliminate first, confirm second: Never try to confirm the right answer before eliminating two obviously wrong options. Wrong options are usually there because they represent a common confusion (like राजपूती vs राजपूतानी).
Step 3 — Use the pattern rule, not rote memory: If you recognize the pattern (conjunct = तत्सम, आनी = title feminine, गण = respected collective), you don't need to have memorized the specific word. The rule generates the answer.
Time target: Each Hindi grammar question should take 30-45 seconds maximum.
Why this question: Tests your knowledge of collective suffixes for बहुवचन — a direct application of संज्ञा वचन rules.
Solving path: "सुधि" means an educated/wise person (a respected human category). For respected human/divine collectives, गण is the standard suffix: सुधिगण, just as श्रोतागण or देवगण. वृन्द is literary but rare; वर्ग is for categories, not persons; जन is for common people. Eliminate वर्ग and जन first, then choose गण over वृन्द because सुधि refers to respected persons, not literary poetic groups.
Why this question: एक शब्द प्रतिस्थापन — tests prefix knowledge and word formation.
Solving path: The phrase "जिसका कोई आकार न हो" = without form/shape. Apply the नि/निर prefix rule: "निर" means without, "आकार" means form → निराकार. Check options: गोलाकार (round-shaped), साकार (with form), आकार (form itself) — all three have आकार present, not absent. Only निराकार means "without form." Eliminate in 8 seconds.
Why this question: Direct तत्सम identification — the most common origin-based question type.
Solving path: "गमिह" — notice the ending "-इह" which is a Sanskrit verbal noun suffix. It carries no phonetic simplification and no regional or foreign character. Apply the conjunct/formal-ending test: this is a Sanskrit word used without modification → तत्सम. देशज would mean regional origin; विदेशज would mean Arabic/Persian/English origin; तद्भव would require a changed form of a Sanskrit original (and you would recognize the Sanskrit parent separately).
Why this question: एक शब्द प्रतिस्थापन with सु prefix — tests compound word analysis.
Solving path: "जिसे सरलता से पढ़ा जा सके" = that which can be easily read. Key word: "सरलता से" → prefix सु (good/easy). "पढ़ा जा सके" → पाठ्य (readable). Combine: सु + पाठ्य = सुपाठ्य. Check the other options: सुषुप्सा (desire to sleep, unrelated), स्थानापन्न (substitute, unrelated), पाठ्य (readable, but without the "easily" component). Only सुपाठ्य carries both the ease and the reading meaning.
Why this question: स्त्रीलिंग formation for a caste/community noun — the -आनी suffix trap.
Solving path: "राजपूत" is a community/caste title noun. Apply the rule: title/caste nouns → feminine uses -आनी suffix. राजपूत + आनी = राजपूतानी. Now eliminate: राजपूती is an adjective (meaning "belonging to Rajputs"), not a feminine noun form; रजपूताई is a regional variant not accepted in standard Hindi; राजपूतरीन follows the -रीन pattern which is not a standard Hindi suffix. राजपूतानी is the only grammatically standard form.
Why this question: Identifies तद्भव definition directly — tests conceptual clarity.
Solving path: The question asks how तद्भव words are formed. The definition: तद् (Sanskrit) + भव (born from) = born from Sanskrit with changes. So: "संस्कृत शब्दों में कुछ बदलाव से" is correct. Eliminate: उर्दू शब्दों में बदलाव — that would be a borrowed/adapted word from Urdu; हिंदी के मूल शब्दों से — that describes देशज; विदेशी शब्दों से — that describes विदेशज. Only option A matches the definition of तद्भव.
Confusing तद्भव with देशज: Students often label everyday words (like दूध, हाथ, आग) as देशज because they sound "native." They are actually तद्भव — they have identifiable Sanskrit parents (दुग्ध, हस्त, अग्नि). देशज words have no traceable Sanskrit origin.
Using -ई as स्त्रीलिंग for community nouns: राजपूती is an adjective (Rajput-style/culture), not the feminine of राजपूत. The moment you see a community or title noun, switch to -आनी, not -ई.
Choosing वृन्द over गण for respected persons: वृन्द appears in poetry (as in वृन्दावन) and is used for literary/divine groups sometimes, but गण is the standard collective suffix for respected human and divine groups in exam contexts. When in doubt, गण wins.
Forgetting that विदेशज includes both Urdu/Arabic AND English: Many students think विदेशज only means English loanwords. Persian and Arabic borrowings (किताब, दुकान, अदालत) are equally विदेशज. If you see an Arabic or Persian-origin word in options, don't mark it as देशज.
Applying -इयाँ to masculine nouns ending in -ई: The -इयाँ rule applies specifically to feminine nouns ending in -ई. Masculine nouns ending in -ई (like पानी, मोती) form plurals differently (पानी stays पानी; मोती → मोती). Mixing this up costs you marks.
Assuming every prefix-modified word is a one-word substitution: In elimination, students sometimes pick a word just because it starts with the right prefix, without checking whether the root after the prefix actually matches the phrase. Always verify both the prefix AND the root word before confirming your answer.
