Grammar specifics by language

Grammar specifics by language

Story hook

It is October 2022, Mains hall, Bhopal. A Hindi-medium candidate writes her translation answer: "राजनीतिक स्थिरता तथा आर्थिक विकास दोनों आवश्यक हैं।" (Political stability and economic development both are necessary.)

The examiner circles तथा in red and writes "and" above it. She circles दोनों and writes "both." Below the sentence she writes: "Redundant. Choose one — either तथा or दोनों, not both." Marks lost on translation: 1.5 of 3. Multiply this across the 20 sentences in the translation section, and the candidate loses 8-12 marks — purely from grammar habits learned wrong and never corrected.

A Bengali candidate next to her makes a parallel mistake. She writes: "আমি যাইতেছি" (I am going, in shadhu-bhasha) in a cholito-bhasha letter to a friend. The examiner marks: "Register mismatch — shadhu in informal context." Score lost: 2 of 5.

A Tamil candidate three rows away writes the verb form "varuvāy" (you will come, masculine plural) when addressing a single woman politely. Tamil's complex pronoun-and- verb honorific system has tripped her up. Marks lost: 1 of 4.

Grammar mistakes in the Indian Language Qualifying paper are systematic, identifiable, and avoidable. Each language has its own most-tested 10 grammar points, and a candidate who drills these specifically gains 12-18 marks on top of comprehension and essay scores. This unit catalogues the high-yield grammar points language-by-language.

Why this matters for UPSC

The Indian Language Qualifying paper carries 300 marks. Grammar competence is tested across all four sections: comprehension (vocabulary + sentence-parsing), précis writing (grammatical compression), short essays (verb tense consistency, voice), and translation (word-for-word and sense-for-sense). UPSC examiners are explicitly trained to deduct marks for:

  • Verb-noun agreement errors.
  • Tense-shift errors (mixed past and present inappropriately).
  • Honorific mismatch (using आप form with तू verb).
  • Register slippage (mixing high-classical with colloquial).
  • Spelling errors in archaic or compound words.
  • Punctuation errors in passage-based answers.

Across the 300-mark paper, grammar deductions account for 20-30 marks of typical loss. The candidate who studies grammar specifically for 15-30 hours over a month can shrink this loss to 5-8 marks — a net 15-20 mark gain.
