Questions & Answers about Yönerge net olsun diye adımları tek tek yazdım.

What does the part with olsun diye do in this sentence?

It introduces a purpose clause: ... olsun diye means “so that ... (will) be.” Here, Yönerge net olsun diye = “so that the instruction is clear.” The verb is in the optative mood (a “let it be”/desired outcome), which is standard for purpose clauses with diye.

Why is it olsun and not olmak or something else?

Olsun is the 3rd person singular optative of ol- “to be,” used to express a wished-for result. With diye, Turkish prefers a finite verb in the optative: “(so that it) be (clear).” Using the bare infinitive olmak here would be ungrammatical with diye.

Can I say Yönergenin net olması için adımları tek tek yazdım instead?

Yes. That’s also natural and a bit more formal/neutral. Differences:

• ... olsun diye: slightly more colloquial and direct, feels like “so that it will be (clear).”
• ... olması için: uses a nominalized clause with için “for/in order to,” stylistically a touch more formal. Meaning is the same.

What is the subject of olsun?

Yönerge is the subject of the subordinate clause: “[The instruction] be clear.” The main clause’s subject is “I,” expressed by the verb ending -dım in yazdım.
