Learn Farsi: به دلیل اینکه هدف مشترک نداشتند، انسجام گروه از بین رفت. - Because they didn't have a shared goal, the cohesion of the group was lost.

The word ensejâm uses the Arabic root s-j-m (relating to flowing or harmony) plugged into the en-C1-e-C2-â-C3 pattern. This Form VII pattern often describes an internal change, yielding, or a passive state. Here, it creates a noun meaning cohesion or harmony, representing the state of a group yielding its individual parts to form a unified whole.

The English translation says 'was lost,' but what is the literal meaning of az beyn raft?

The phrase literally means 'went from between.' The compound verb az beyn raftan is the standard Farsi way to express that something was destroyed, ruined, disappeared, or, as in this case, lost completely.

Why does the Farsi sentence use hadaf-e moshtarak without any indefinite markers like yek or -i for 'a shared goal'?

With negative forms of dâshtan (like nadâshtand), Farsi typically drops the indefinite -i suffix and the word yek (a/one). Using the bare noun phrase hadaf-e moshtarak is the most natural way to express that they lacked any shared goal entirely.

Is there a difference between using be dalil-e inke and chon here?

Both mean 'because,' but be dalil-e inke (literally 'for the reason of this that') is slightly more formal and analytical than the everyday word chon. It is commonly used in B2-level texts and formal speech to emphasize a clear, logical cause-and-effect relationship.
