To state that an action will not happen, Farsi uses the negative form of the future tense. Just as in the affirmative future tense, we use the helper verb خواستن alongside the short infinitive of your main action.
Negating the Future Tense
To make a future sentence negative, you simply negate the auxiliary verb. Add the negative prefix نـ to the conjugated forms of خواستن.
Here are the negative auxiliary forms used to build the negative future tense:
| Person | Negative Auxiliary | Meaning |
|---|---|---|
| 1st Singular | نخواهم | I will not |
| 2nd Singular | نخواهی | You (sg.) will not |
| 3rd Singular | نخواهد | He/She/It will not |
| 1st Plural | نخواهیم | We will not |
| 2nd Plural | نخواهید | You (pl.) will not |
| 3rd Plural | نخواهند | They will not |
Using with Compound Verbs
When discussing environmental conservation, you will use many compound verbs, such as آلوده کردن (to pollute) or نابود کردن (to destroy).
Remember that in the future tense, the auxiliary verb splits the compound. Place the negative conjugated form of خواستن exactly after the non-verbal part (the noun or adjective) and before the short infinitive of the verbal part.
Here is how this formula looks in practice:
| I will not destroy the trees of the forest. | من درختهای جنگل را نابود نخواهم کرد.man derakht-hâ-ye jangal râ nâbud nakhâham kard. |
| We will not pollute the environment. | ما محیط زیست را آلوده نخواهیم کرد.mâ mohit-e zist râ âlude nakhâhim kard. |
| They will not destroy nature. | آنها طبیعت را نابود نخواهند کرد.ânhâ tabi'at râ nâbud nakhâhand kard. |
| You will not protect the environment without clean energy. | شما بدون انرژی پاک از محیط زیست محافظت نخواهید کرد.shomâ bedun enerzhi pâk az mohit-e zist mohâfezat nakhâhid kard. |
Notice how the main verb remains as a short infinitive (like کرد) while the negated helper verb (like نخواهیم) carries the tense and person.
