Four Sentences, Three Tense Traps
During a 15-minute class test, a Class X candidate is asked to translate four Hindi sentences into Persian. Her answers are:
- «मैं रोज़ स्कूल जाता हूँ» → «من هر روز به مدرسه می‌روم.»
- «वह कल किताब पढ़ेगा» → «او دیروز کتاب خواند.»
- «हम लोग अध्यापक हैं» → «ما معلم هست.»
- «मैं चाय पीना चाहता हूँ» → «من چای می‌خواهم می‌نوشم.» The paper carries 8 marks, 2 per sentence. Sentence 1 is fully correct. The teacher has to award partial credit and write one feedback line per error, not merely mark wrong. The class has already learned present, simple past, future with «خواهد», the copula «است/هستم/هستیم», and «خواستن + subjunctive». The teacher must distinguish tense errors from agreement errors and from sentence-pattern errors, because the same student will sit a 50-mark board paper in which these are separate question types.
1. Diagnose sentences 2–4: what exactly is wrong in each, and what mark out of 2 would you award? Justify each mark by error type.

Use the rubric as two separate decisions: tense/mode and agreement.
- Sentence 2: «او دیروز کتاب خواند.» The target is future «فردا ... خواهد خواند». Two errors: the adverb is past («دیروز») not future («فردا»), and the verb is simple past, not future. Award 0/2, or at most 1 if the board gives credit for correct subject and object; the tense question itself is wrong.
- Sentence 3: «ما معلم هست.» The subject «ما» is first-person plural, so the copula must be «هستیم»: «ما معلم هستیم.» Award 1/2: the copula choice is right, but agreement is wrong. This is an agreement error, not a tense error.
- Sentence 4: «من چای می‌خواهم می‌نوشم.» «خواستن» takes a subjunctive complement: «من می‌خواهم چای بنوشم.» The student used the indicative «می‌نوشم», so the sentence pattern is wrong. Award 0/2 or 1 for vocabulary only. The key is not to merge all three into 'grammar'; the board paper separates tense, agreement and verb patterns.
2. Explain the difference between «هست» and «است» and show why «ما معلم هستیم» is the correct form.

«هست» and «است» are both copula forms, but they are not interchangeable in every person. «است» is third-person singular: «او معلم است.» «هست» is the full existential/copula stem and carries person endings: هستم، هستی، هست، هستیم، هستید، هستند. In «ما معلم هستیم», the subject is «ما» (1pl), so the ending must be -یم. «ما معلم هست» fails because «هست» is 3sg. If the student writes «ما معلم است», that is even more clearly wrong because «است» is frozen for 3sg. The corrected sentence is «ما معلم هستیم.» A useful contrast: «او معلم است» and «او معلم هست» can both occur, but «ما» requires «هستیم».
3. Rewrite sentence 4 in two grammatical ways and say which is more natural for a school composition, with reasons.

Two possible rewrites:
- «من می‌خواهم چای بنوشم.» - the most neutral and the pattern taught with «خواستن + subjunctive».
- «من چای نوشیدن می‌خواهم.» - grammatical but marked; it nominalizes the verb and sounds more formal. The first is more natural for a school composition because it keeps the modal verb first and the subjunctive at the end. The second is acceptable but should not be presented as the default. Both keep the object «چای» before the verb, which matches Hindi word order and helps the learner; the error to avoid is «می‌خواهم می‌نوشم», where two indicatives are stacked.
