Learn Farsi: در این گزارش مبالغه وجود دارد.

mobâleghe comes from the Arabic root b-l-gh (b - l - gh), which relates to reaching or attaining (you might recognize it in bâlegh, meaning adult). Plugging these root letters into the mo-C1-â-C2-e-C3-e pattern gives us mo-b-â-l-e-gh-e. While Form III often implies mutual engagement, it can also denote attempting to surpass something or taking an action to an extreme, which perfectly describes exaggeration.

The Arabic pattern is technically mufâ'ala(t). Why does mobâleghe end with an -e sound here?

When Farsi borrows Arabic words that end in the feminine ta marbuta suffix (which acts like '-at' or '-ah' in Arabic), it routinely changes that ending to a short -e sound, written with a silent heh. You will see this typical Farsi adjustment in almost all words following this pattern, such as mosâhebe (interview) and mobâreze (struggle).

Why does this sentence use vojud dârad for 'there is' instead of just ast?

vojud dârad literally translates to 'has existence' (vojud means existence). Farsi uses this phrase (or the shorter hast) to declare that something exists in the world ('there is' or 'there are'). You cannot use ast here because ast only functions as a linking verb used to equate or describe things (for example, 'The report ast long').
