Learn Farsi: همه‌ی گروه‌ها با این پروژه موافق هستند.

The word for all is hame (همه). To connect it to the noun it describes, we need the linking vowel called Ezafe. Because hame ends in an invisible e sound (written with the letter heh ه), the Ezafe is written with a ye (ی) and pronounced as -ye. So, we get hame-ye (همه‌ی).

Do we always use a plural noun after hame-ye?

Yes, if the noun is countable. Unlike numbers (which take singular nouns in Farsi), the word hame requires countable nouns to be plural. That is why we see goruh-ha (گروه‌ها) with the plural suffix -ha, rather than just the singular goruh.

Where is the verb for agree in this sentence?

In Farsi, the concept of agreeing is usually expressed using an adjective and the verb to be. This sentence uses movafeq (موافق), which means in agreement, followed by hastand (هستند) meaning they are. Literally, it translates to they are in agreement.

Is it normal to use ba (با) for agreeing with a project?

Yes! Just like in English, you agree with someone or something. In Farsi, you use ba (with) before the person or thing you agree with. Here, it is ba in prože (with this project).
