Tanık bu çelişkiyi fark etti.

A simple breakdown is:

• Tanık = the subject, witness
• bu çelişkiyi = the direct object, this contradiction
• fark etti = the verb phrase, noticed

So the structure is:

• Subject + Object + Verb

That is the most neutral Turkish word order here.

It can mean either, depending on context.

Turkish does not have articles like a and the. A bare noun such as tanık can be:

• a witness
• the witness

In a sentence like this, English often uses the witness if the witness is already known from the context. If the person is being introduced for the first time, English might use a witness.

Because çelişki is the direct object and it is definite/specific, so Turkish uses the accusative ending.

Here:

• çelişki = contradiction
• çelişkiyi = the contradiction / this contradiction, as a marked direct object

The accusative ending is -(y)ı / -(y)i / -(y)u / -(y)ü, chosen by vowel harmony.

Since the object has bu = this, it is already specific, so accusative marking is expected.

Compare:

• Tanık bir çelişki fark etti = The witness noticed a contradiction
• Tanık bu çelişkiyi fark etti = The witness noticed this contradiction

That y is a buffer consonant.

The noun çelişki ends in a vowel, and the accusative ending here also begins with a vowel. Turkish usually inserts y between two vowels to make pronunciation easier.

So:

• çelişki + i would sound awkward
• Turkish uses çelişki + y + i
• Result: çelişkiyi

This happens in many Turkish words:

• kapı → kapıyı
• arabayı
• masayı

Because fark etmek is a standard noun + etmek verb construction.

• fark = difference, distinction, awareness
• etmek = to do, to make

Together, fark etmek means to notice, to realize, or to become aware of.

Turkish has many expressions like this, and they are normally written as two words:

• yardım etmek = to help
• kabul etmek = to accept
• takip etmek = to follow

So fark etti is the correct standard spelling.

Etti is the simple past tense of etmek.

The infinitive is:

• etmek = to do / to make

Past tense is formed with the suffix often shown as -DI, whose actual form changes according to sound rules.

Here:

• et-
  • -ti → etti

So fark etti means noticed or realized in the past.

This is the regular witnessed/definite past in Turkish, the past tense used for a completed event.

Because the verb stem is et-, and the past tense suffix here appears as -ti.

So:

• et + ti = etti

That creates tt in writing and pronunciation.

This is completely normal in Turkish. It is not an irregular spelling.

Not word-for-word, but as a whole expression, yes.

Literally:

• fark often relates to difference or distinction
• etmek means to do/make

But together, fark etmek is an established expression meaning:

• to notice
• to realize
• to become aware of

So it is best learned as one unit, not translated too mechanically word by word.

Because Turkish normally prefers Subject–Object–Verb word order.

So this sentence is:

• Tanık = subject
• bu çelişkiyi = object
• fark etti = verb

English usually puts the verb before the object, but Turkish typically places the main verb at the end in neutral statements.

Yes. Turkish word order is flexible, but changes usually affect emphasis, not the core meaning.

The most neutral version is:

• Tanık bu çelişkiyi fark etti

Other orders are possible in context, for example:

• Bu çelişkiyi tanık fark etti
  This can emphasize this contradiction or contrast the witness with someone else.

But for a learner, the given sentence is the most straightforward and natural order.

A rough guide:

• Tanık ≈ tah-nuhk, but the ı has no exact English equivalent. It is a back, unrounded vowel, something like a muted uh.
• bu = boo
• ç = ch
• ş = sh
• çelişkiyi ≈ cheh-leesh-kee-yee
• fark etti ≈ fark et-tee

Some key letters:

• ç = ch as in church
• ş = sh as in shoe
• ı = a vowel English does not really have; it is not the same as i

So the whole sentence is approximately:

• tah-nuhk boo cheh-leesh-kee-yee fark et-tee

Yes, if the subject were already clear from context.

Turkish often drops subjects because the verb ending can show the person. However, in the third person singular past, etti does not uniquely identify the subject as clearly as first- or second-person forms do, so context matters more.

Still, Turkish often keeps the noun subject when it is important, new, or contrastive. So using Tanık here is perfectly natural.
