When discussing official programs, such as municipal recycling or waste management, you often need to cite rules, schedules, and policies. Farsi uses a few common prepositions to mean "according to" or "based on." Just like other prepositions, these link to the noun that follows them using the unseen ezafe vowel.
According to (طبق)
The word طبق translates to "according to" or "as per." It is frequently used to reference schedules, lists, and direct instructions.
| According to this schedule, the municipality's trucks will collect the waste tomorrow. | طبق این جدول، ماشینهای شهرداری پسماند را فردا جمعآوری میکنند.tebq-e in jadval, mâshin-hâ-ye shahrdâri pasmând râ fardâ jam'âvari mikonand. |
| According to this resolution, one of the most important goals is stopping waste landfilling. | طبق این مصوبه، یکی از مهمترین اهداف، متوقف کردن دفن زباله است.tebq-e in mosavvabe, yeki az mohemtarin ahdâf, motevaqqef kardan-e dafn-e zobâle ast. |
Based on (بر اساس)
To say "based on" or "on the basis of," use بر اساس. This phrase is widely used when citing directives, policies, or standard procedures.
| Based on the new municipality directive, nobody leaves waste here. | بر اساس بخشنامهی جدید شهرداری، هیچکس پسماند را اینجا رها نمیکند.bar asâs-e bakhshnâme-ye jadid-e shahrdâri, hich-kas pasmând râ injâ rahâ nemikonad. |
| Based on the standard procedure, we produce compost from these vegetables. | بر اساس رویهی استاندارد، ما از این سبزیجات کمپوست تولید میکنیم.bar asâs-e raviye-ye estândârd, mâ az in sabzijât kompost towlid mikonim. |
In Accordance With (مطابق)
For formal compliance, such as acting "in accordance with" or "conforming to" an official resolution, use مطابق.
| In accordance with this resolution, we must recycle glass and plastic. | مطابق این مصوبه، ما باید شیشه و پلاستیک را بازیافت کنیم.motâbeq-e in mosavvabe, mâ bâyad shishe va pelâstik râ bâzyâft konim. |
Like the other prepositions of accordance, this phrase can appear at the very beginning of the sentence to establish context, or it can be embedded later in the clause alongside the subject or time words.
| In accordance with the schedule, the workers will distribute the compost tomorrow. | مطابق جدول زمانبندی، کارگران فردا کمپوست را پخش میکنند.motâbeq-e jadval-e zamân-bandi, kârgarân fardâ kompost râ pakhsh mikonand. |
