Word purity (shabd-shuddhi)

Word purity in the RPSC SI Hindi paper means recognising whether an individual Hindi word has the standard spelling, visible form and accepted educated usage expected in an objective question. Word purity, or shabd-shuddhi, is narrower than sentence purity. Sentence purity, or vakya-shuddhi, asks whether a sentence has the correct case relation, gender, number, tense, word order, agreement or idiom. Word purity asks whether the individual word itself is acceptable in standard usage: for example, whether the expected form is parishad with the final halant or parishad without it, nishkarsh or nishkarsh with the wrong sha sound, anugrah or anugrah with an inserted visarga, prashasak or prashashak, aashirvaad or aashirvad with the wrong vowel length, abhyarthi or abhyarthi with the misplaced ya sound. According to the RPSC Sub Inspector syllabus, Paper I Hindi carries 200 marks.

In an RPSC SI Hindi paper, this distinction matters because the syllabus keeps shabd-shuddhi separate from vakya-shuddhi, and the question paper pattern is objective. The candidate is often not asked to explain a rule; the candidate is asked to choose the shuddh or ashuddh form quickly. The point is not literary display. The point is visible accuracy under time pressure. A candidate who understands the rule but misses one matra, one nasal mark or one conjunct can still lose the mark.

The working definition is practical: a word is shuddh when its spelling, matra, nasal mark, conjunct consonant, halant use and accepted standard form match educated Hindi usage. A word is ashuddh when one visible element has been changed, omitted, added or colloquialised in a way that makes the form non-standard. The error may be small but decisive. The difference between kshama and chhama is not a stylistic preference; the first is the standard word. The difference between drashtavya and drishtavya is not random in a word-purity option; drashtavya is the shuddh form when the intended word means worthy of being seen or noted, while the rival form is treated as ashuddh in such questions. The difference between antargat with the standard anusvar spelling and antargat written in an older half-na style can be script-style dependent, but the question normally expects one form based on the printed standard in the options. The safest preparation is therefore to learn the commonly tested contrasts rather than argue from memory inside the exam hall.

RPSC-style word-purity questions tend to use compact option sets. One format asks the candidate to choose the incorrect word. Another asks the candidate to choose the correct word. A third gives four options, each containing a cluster of words, and asks which option contains all correct words or all incorrect words. That third format is dangerous because one correct word in a cluster does not save the option if another word is wrong. Candidates should therefore scan every word, not only the first familiar item. A useful routine is to mark visible traps first: short i and long ii, short u and long uu, ri, anusvar or chandrabindu, sha or sha or sa, ja or gya, ksha or chha, dya or da, tra or ta, and doubled consonants. Then check whether the word is a standard tatsam form or an accepted tadbhav form, because many mistakes arise when a colloquial pronunciation is written as if it were formal Hindi.

The topic also touches word-type awareness without becoming a full lesson on tatsam, tadbhav, deshaj and videshi words. If a paper separately asks word-type classification, that is a different skill. In shabd-shuddhi, the point is that knowing origin helps spelling. A tatsam form often preserves conjuncts and Sanskritic spelling: kshatriya, prashn, darpan, vidvaan, sanskrit, nihshabd. A tadbhav or common Hindi form may be standard even though it is not tatsam: kaccha, pakka, devar, bahu, aankh. The exam trap is not that every Sanskrit-looking form is correct. The trap is that the correct standard depends on the actual accepted word. Preparation should therefore build a contrast bank: one word, one likely wrong neighbour and one reason the correct form wins. That habit turns shabd-shuddhi from guesswork into controlled recognition.
