Questions & Answers about میخواهم غذا زیاد بخرم مبادا تمام شود.
Why is the verb after مبادا affirmative (تمام شود) when it means 'so that it doesn't run out'?
The word مبادا already carries a negative meaning ('lest' or 'so that... not'). Because the negative idea is built into the conjunction itself, the verb that follows it stays in the affirmative. Adding a negative prefix to the verb (like تمام نشود) would create an unwanted double negative.
Why is the final verb شود in the subjunctive form?
The conjunction مبادا expresses a fear, possibility, or intention to avoid something happening. Because this event hasn't actually happened and is just a hypothetical outcome you want to prevent, Farsi requires the present subjunctive.
Why isn't there an ezafe connecting غذا and زیاد (like غذای زیاد)?
While you certainly can say غذای زیاد to mean 'a lot of food' using an ezafe, here زیاد is acting as an adverb modifying the verb بخرم. Structurally, it translates closer to 'I want to buy food abundantly' or 'I want to buy food a lot.'
If شود is in the subjunctive, why doesn't it have the بـ (be-) prefix?
