Learn Farsi: من خوشحالم از اینکه آنچه مرشد انتقال می‌دهد، حکمت است. - I am happy that what the mentor passes down is wisdom.

Using آنچه (that which / what) creates a pseudo-cleft sentence. Instead of a flat statement, this structure builds anticipation. It frames "what the mentor passes down" as the topic, placing a strong thematic focus and emphasis on the final reveal: حکمت (wisdom).

Could we say آنچه که (ânche ke) in this sentence instead of just آنچه?

Yes, absolutely. آنچه and آنچه که both mean "that which" or "what" in this context. Adding که (ke) explicitly marks the start of the relative clause and is very common in everyday Farsi. Using just آنچه without که sounds slightly more formal or literary, which perfectly fits the elevated tone of talking about a mentor and wisdom.

Why do we need از اینکه (az inke) right before the آنچه clause? Why not just link it with که (ke)?

In Farsi, adjectives expressing emotion like خوشحال (khoshhâl) are usually followed by the preposition از (from/about). Because prepositions cannot directly attach to a full clause, Farsi uses این (this) as a structural bridge. So, از اینکه literally translates to "from this that," but it functions in English simply as "that" or "about the fact that."

The translation says انتقال می‌دهد (enteghâl midahad) means "passes down." Is this a specific verb meant only for passing down knowledge?
