Learn Farsi: اون پسر به اندازه‌ی برادرم لجبازه و خیلی خسیسه. - That boy is as stubborn as my brother, and very stingy.

be andâze-ye literally means 'to the size of' or 'to the extent of'. To say 'as stubborn as my brother', the Farsi phrasing is 'to the extent of my brother, stubborn'. You put be andâze-ye, then the noun you are comparing to (barâdar-am), and finally the adjective (lajbâz).

Why is there a -ye attached to andâze?

The word andâze (measure or size) ends in a silent 'h' that makes an 'e' sound. To connect it to the next word (barâdar-am) using the ezâfe linker, Farsi adds a 'y' sound to bridge the vowels. That is why it becomes andâze-ye.

What is the -e at the end of lajbâze and khasise?

That -e at the end of lajbâze and khasise is the spoken, shortened form of ast (is). In conversational Farsi, lajbâz ast smoothly becomes lajbâze and khasis ast becomes khasise.

Why are lajbâze and khasise placed at the very end of their phrases?

Verbs usually go at the end of their clause in Farsi. Because the verb 'is' is attached as a suffix (-e) to the adjectives here, lajbâze and khasise naturally fall at the end of their respective parts of the sentence. You would not put immediately after .
