Questions & Answers about Bu plan arkadaşlarla birlikte oluşturuldu.

What does bu mean in Bu plan?

bu is a demonstrative pronoun meaning “this.” In Bu plan, it points to a specific plan close to the speaker or context—i.e. “this plan,” not “that plan.”

Why isn’t plan marked with an accusative suffix (like planı)?

In a passive sentence, the original object becomes the subject and takes the nominative (no accusative). Here plan is the subject of the passive verb oluşturuldu, so it stays in the nominative case without -ı.

What does arkadaşlarla birlikte mean, and can I say just one of them?

• arkadaşlarla means “with friends” (instrumental case of arkadaş).
• birlikte means “together” (adverb).
  Together they emphasize “together with friends.” You could say arkadaşlarla oluşturuldu (with friends it was created) or birlikte oluşturuldu (it was created together), but combining them makes the meaning crystal-clear.

Is the word order of arkadaşlarla birlikte flexible?

Yes. Turkish allows some flexibility. Common patterns include:

• Arkadaşlarla birlikte oluşturuldu.
• Birlikte arkadaşlarla oluşturuldu.
  Placing birlikte before or after arkadaşlarla changes emphasis slightly but is grammatically fine.

What is oluşturuldu, and how do you form this passive?

oluşturuldu is the 3rd person singular simple-past passive of oluşturmak (“to create/form”). Formation steps:

1. Drop -mak, leaving oluştur-.
2. Add passive suffix -ul (vowel-harmonized from -il → -ul) → oluşturul-.
3. Add past tense -du → oluşturuldu (with an implicit 3rd person singular ending Ø).

Why use passive voice here? How would it look in active voice?

The passive highlights plan as the focus, not the doer. In active voice with an explicit subject, you’d say:
Biz bu planı arkadaşlarımızla birlikte oluşturduk.
(We created this plan together with our friends.)

Can I use tarafından instead of arkadaşlarla to show the agent?

Yes, tarafından is the formal passive agent marker. You’d say:
Bu plan arkadaşlar tarafından oluşturuldu.
(more formal, “This plan was created by friends”). In everyday Turkish, arkadaşlarla birlikte oluşturuldu sounds more natural.

What’s the difference between birlikte and beraber?

Both mean “together” and are largely interchangeable. birlikte is a bit more formal; beraber is more colloquial. You can use either:

• Arkadaşlarla birlikte oluşturuldu.
• Arkadaşlarla beraber oluşturuldu.

Why isn’t there a subject pronoun like biz or onlar in the sentence?

In a passive construction, the grammatical subject is the thing acted upon (here plan). The doer can be omitted or expressed by an adverbial phrase (arkadaşlarla birlikte). Subject pronouns like biz/ onlar aren’t used because the focus isn’t on “we” or “they.”

What’s the difference between oluşturuldu and oluşturulmuş?

• oluşturuldu (-du) is simple past passive: “it was created” (definite event).
• oluşturulmuş (-muş) is reported/experiential past: “it seems it was created” or “it has been created,” often implying the speaker didn’t witness it directly.
