Dedikodu açıkçası herkesi yordu.

The subject is dedikodu and the object is herkesi.

• dedikodu = gossip
• herkesi = everyone / everybody (as the thing/person affected by the action)

The verb is yordu, so literally the structure is:

• Dedikodu = gossip
• açıkçası = frankly / honestly
• herkesi = everyone
• yordu = tired out / wore out

So Turkish is saying: Gossip, frankly, wore everyone out.

Because it is the direct object of the verb.

In Turkish, a definite/specific direct object usually takes the accusative ending.
Here:

• herkes = everyone
• herkesi = everyone (as the direct object)

So:

• Herkes geldi. = Everyone came.
  (herkes is the subject)
• Dedikodu herkesi yordu. = Gossip tired everyone out.
  (herkesi is the object)

The -i ending marks that everyone is receiving the action.

Açıkçası means something like:

• frankly
• honestly
• to be honest
• to tell the truth

It is a sentence adverb, meaning it comments on the whole statement rather than describing the verb directly.

So in this sentence, the speaker is adding a tone like:

• Frankly, gossip wore everyone out.
• Honestly, the gossip tired everyone out.

It does not mean openly here. It is more about the speaker’s attitude.

Yordu comes from the verb yormak, which means:

• to tire
• to exhaust
• to wear out

Breakdown:

• yor- = verb stem
• -du = past tense ending

So:

• yormak = to tire
• yordu = (it) tired / wore out

In this sentence, the understood subject is dedikodu, so:

• Dedikodu ... yordu. = The gossip tired ...

Because the verb agrees with the subject, not the object.

The subject is dedikodu, which is singular. So the verb is singular too:

• Dedikodu yordu. = The gossip tired (someone).

Herkesi is the object, so it does not control the verb ending.

Turkish does not have articles like a/an and the.

So dedikodu can often be understood from context as:

• gossip
• the gossip
• some gossip
• sometimes even gossiping, depending on context

In this sentence, it most naturally refers to gossip / the gossip in a general or context-based sense.

So learners should not try to find a separate Turkish word for the here—there usually isn’t one.

Yes, Turkish word order is flexible, but the verb usually comes at the end.

This sentence has:

• Dedikodu = subject
• açıkçası = sentence adverb
• herkesi = object
• yordu = verb

This is a natural order.

But Turkish can move parts around for emphasis, for example:

• Açıkçası dedikodu herkesi yordu.
• Dedikodu herkesi açıkçası yordu. (less natural in many contexts, but possible with a special emphasis)

The original sentence sounds quite natural and balanced.

Yes. That is very common.

For example:

• Açıkçası, dedikodu herkesi yordu.

This may sound a little more like standard English Frankly, ...

In the original sentence, putting açıkçası after dedikodu still sounds natural, but gives slightly different rhythm and emphasis.

This is a very useful distinction.

• açıkçası = frankly / honestly / to be honest
• açıkça = openly / clearly / explicitly

So in this sentence, açıkçası is the correct choice if the meaning is about the speaker’s attitude.

Compare:

• Açıkçası bilmiyorum. = Honestly, I don’t know.
• Açıkça söyledi. = He/She said it openly / clearly.

So açıkçası is not simply the adverb form of açık in the same way English learners might expect.

Yes. Yormak is a transitive verb, so it can take a direct object.

Examples:

• Bu iş beni yoruyor. = This work is tiring me out.
• Sıcak herkesi yordu. = The heat wore everyone out.
• Dedikodu herkesi yordu. = Gossip wore everyone out.

That is why herkesi appears in the accusative.

Yes, absolutely.

Yormak can mean:

• physically tire
• mentally exhaust
• emotionally wear out

With dedikodu, the meaning is usually more like:

• wore everyone out
• exhausted everyone
• got tiring for everyone

So it often suggests social or emotional exhaustion rather than literal physical tiredness.

Because it is the subject of the sentence.

In Turkish, subjects are normally in the bare form (nominative, with no special ending).

So:

• Dedikodu = subject
• herkesi = object, so it gets -i

This contrast is very common in Turkish:

• Köpek adamı ısırdı. = The dog bit the man.
  • köpek = subject
  • adamı = object

Likewise:

• Dedikodu herkesi yordu.
  • dedikodu = subject
  • herkesi = object

Yes.

In Turkish, herkes means everyone / everybody, and it behaves grammatically like a singular word in many situations.

So:

• Herkes burada. = Everyone is here.
• Onu herkes tanıyor. = Everyone knows him/her.
• Dedikodu herkesi yordu. = The gossip wore everyone out.

This is similar to English, where everyone is also grammatically singular in some contexts, even though it refers to many people.
