Setting Boundaries: "As Far As"
When you want to qualify your statements by saying "as far as" or "to the extent that," Farsi uses the phrase تا جایی که (literally: "to the place that"). This is incredibly useful for clarifying the limits of your knowledge or information.
Because you are stating the reality of what you know right now, the verb following تا جایی که takes the regular indicative mood (like the simple present or past), rather than the subjunctive.
| As far as I know, his knowledge in this field is limited. | تا جایی که من میدانم، دانش او در این زمینه محدود است.tâ jâyi ke man midânam, dânesh u dar in zamine mahdud ast. |
You can pair this phrase with various ways of saying "I know" or "I am informed," such as خبر دارم (I have news/am informed) or آگاهی دارم (I have awareness).
| As far as I am informed, he is studying a particular major. | تا جایی که من خبر دارم، او یک رشتهای میخواند.tâ jâyi ke man khabar dâram, u yek reshte-i mikhânad. |
| As far as I am aware, nobody knows the source of this news. | تا جایی که من آگاهی دارم، هیچکس منبع این خبر را نمیداند.tâ jâyi ke man âgâhi dâram, hich-kas manba'-e in khabar râ nemidânad. |
Professional Caveats
In formal or professional settings, you might use adjectives like مطلع (informed) to sound a bit more polished when discussing the accuracy (صحت) of reports or assessing a situation.
| As far as we are informed, the accuracy of this report is not clear. | تا جایی که ما مطلع هستیم، صحت این گزارش معلوم نیست.tâ jâyi ke mâ mottale' hastim, sehhat in gozâresh ma'lum nist. |
| As far as we understand, nobody confirms the accuracy of this story. | تا جایی که ما میفهمیم، هیچکس صحت این داستان را تایید نمیکند.tâ jâyi ke mâ mifahmim, hich-kas sehhat-e in dâstân râ ta'yid nemikonad. |
Limits of Ability and Action
The phrase تا جایی که isn't just for stating what you know; it is also used to describe the practical limits of what someone can do ("to the extent that...").
| As far as I am able, I help with this project. | تا جایی که در توان دارم، به این پروژه کمک میکنم.tâ jâyi ke dar tavân dâram, be in porozhe komak mikonam. |
| As far as they can, they find a particular source in this field. | تا جایی که میتوانند، یک منبعی در این زمینه پیدا میکنند.tâ jâyi ke mitavânand, yek manba'i dar in zamine peydâ mikonand. |
Memory and Absolute Limits
Finally, you can easily pair this structure with verbs of memory ("as far as I remember"), or use it to explicitly point out boundaries and limits (حد).
| As far as I remember, he was not here before the meeting. | تا جایی که یادم است، او قبل از جلسه اینجا نبود.tā jāyi ke yādam ast, u qabl az jalase injā nabud. |
| As far as I know, this is the limit of our knowledge. | تا جایی که من خبر دارم، این حد دانش ماست.tâ jâyi ke man khabar dâram, in hadd-e dânesh-e mâst. |
