Learn Farsi: والدین مخالفت می‌کنند و نمی‌گذارند او برود. - The parents oppose and do not let him go.

In Farsi, verbs of permission like گذاشتن (to let) trigger a new clause rather than using an infinitive like English does. The first verb, نمی‌گذارند (they do not let), is in the present indicative and conjugated for the parents (they). The second verb, برود (that he go), is in the present subjunctive and conjugated for the person doing the action (او, he). Literally, it translates to: They do not let that he go.

Doesn't the verb گذاشتن normally mean "to put"?

Yes, its primary physical meaning is "to put" or "to place." However, when it is followed by the present subjunctive of another verb—like برود in this sentence—its meaning shifts to "to let" or "to allow."

Does the word والدین (parents) have a standard Farsi plural ending?

No, the ending ـین (-eyn) is an Arabic "dual" suffix, which is used for exactly two of something. Because Farsi borrowed this word from Arabic, it kept its special dual form to mean "parents" (the two parents). In everyday conversation, you will also frequently hear پدر و مادر (father and mother).
