Farsi - Negative present perfect (na-)

When a home renovation project is dragging on, you need a way to talk about what hasn't been done yet. For this, we use the negative present perfect tense.

Forming the Negative Present Perfect

To make the present perfect negative, attach the negative prefix نـ (na-) to the past participle. The present perfect endings remain the same.

For example, خریده‌ام (I have bought) becomes نخریده‌ام (I have not bought).

I have not bought the lamps and the bricks yet.

من هنوز لامپ‌ها و آجرها را نخریده‌ام.man hanuz lâmp-hâ va âjor-hâ râ nakharide-am.

The painters have not seen the pipes, because the room is dark.

نقاش‌ها لوله‌ها را ندیده‌اند، چون اتاق تاریک است.naqqâsh-hâ lule-hâ râ nadide-and, chon otâq târik ast.

For compound verbs, only the verbal part (such as کردن) takes the negative prefix.

You have not installed the lamp on the ceiling.

شما لامپ را روی سقف نصب نکرده‌اید.shomâ lâmp râ ruye saghf nasb nakarde-id.

Why haven't you replaced the old tiles?

چرا کاشی‌های قدیمی را عوض نکرده‌اید؟cherâ kâshi-hâ-ye ghadimi râ avaz nakarde-id?

We have not used the bricks for the ceiling.

ما از آجرها برای سقف استفاده نکرده‌ایم.mâ az âjorhâ barâye saqf estefâde nakardeim.

The Third-Person Singular

Remember that the third-person singular uses the separate word است instead of a connected ending. The negative prefix still attaches directly to the past participle.

The painter has not painted the ceiling yet, because it is wet.

نقاش هنوز سقف را رنگ نکرده است، چون خیس است.naqqâsh hanuz saqf râ rang nakarde ast, chon khis ast.

The engineer has not replaced the bricks, because he wants to use glass.

مهندس آجرها را عوض نکرده است، چون می‌خواهد از شیشه استفاده کند.mohandes âjorhâ râ avaz nakarde ast, chon mikhâhad az shishe estefâde konad.
