Learn Farsi: به اینکه اندازه‌گیری دقیق است توجه کنید. - Pay attention to the fact that the measurement is precise.

The compound verb توجه کردن (to pay attention) requires the preposition به (to). When paying attention to a simple noun, you use به + noun. But when you are pointing to a full statement or action (a clause), Farsi bridges the preposition and the clause using اینکه (literally "this that" or "the fact that").

How is the noun اندازه‌گیری (andâze-giri) formed?

It literally translates to "measure-taking." It combines اندازه (size or measure) with گیر (the present stem of گرفتن, to take) and the noun-forming suffix -ی (-i). This is a very common pattern in Farsi for creating abstract nouns from verbs.

Why is the subordinate clause embedded in the middle of the sentence instead of at the end?

In English, we say "Pay attention to the fact that..." with the main verb first. Farsi is strongly Subject-Object-Verb, so the main verb توجه کنید (pay attention) comes at the very end. The entire phrase اینکه اندازه‌گیری دقیق است acts as the object of the preposition به, so it gets sandwiched in the middle, reading literally as: "To the fact that the measurement is precise, attention pay!"

We are learning about decimals and precision. Is دقیق (daqiq) only used for mathematical exactness?

While دقیق is perfect for mathematical measurements and decimals (meaning "exact" or "precise"), it is a versatile word. You can also use it to describe a "punctual" schedule, "accurate" information, or a "meticulous" and "careful" person.
