Questions & Answers about تا جایی که من آگاهی دارم، دانش من در این زمینه محدود است.
Why does tâ jâyi ke (to the extent that) use the indicative verb dâram instead of the subjunctive?
When tâ jâyi ke introduces a statement about a current, established reality—like stating the actual limits of what you currently know—it takes the indicative mood. You would only use the subjunctive if you were talking about a hypothetical, conditional, or future limit.
What is the difference between âgâhi and dânesh, since both relate to knowledge here?
Âgâhi means "awareness" or being informed about a situation. Dânesh means "knowledge," usually referring to deeper learning, expertise, or science. The speaker is essentially contrasting the two: "As far as I am aware (informed on this issue), my actual knowledge (expertise) in this field is limited."
Could I use the verb dânestan (to know) instead of âgâhi dâram?
Yes, absolutely! Tâ jâyi ke midânam (as far as I know) is a very common everyday phrase. The phrase tâ jâyi ke âgâhi dâram (to the extent that I have awareness) means the same thing but is a bit more formal, which perfectly matches the slightly academic tone of discussing a "field" (zamine).
Why is the pronoun man (I) used twice here (man âgâhi dâram, dânesh-e man)? Can I drop them?
You can safely drop the first man because the verb dâram already ends in -am (I). Including it just adds a little emphasis ("As far as am aware..."). The second in (my knowledge) is more important to keep, as it clearly specifies whose knowledge is limited.
