Akciğer görüntüsü biraz bulanıktı.

Because akciğer görüntüsü is a possessive construction in Turkish, literally something like the lung’s image or the image of the lung.

• akciğer = lung
• görüntü = image
• görüntü-sü = its image / image of it

In Turkish, when one noun modifies another in this kind of X of Y relationship, the second noun usually takes a possessive ending:

• akciğer görüntüsü = lung image / image of the lung
• beyin filmi = brain scan/film
• kan basıncı = blood pressure

So görüntüsü is not random—it shows that the image belongs to or is associated with the lung.

The -sü is the 3rd person possessive suffix. It means something like its in this context.

The base word is:

• görüntü = image

With the possessive ending:

• görüntü-sü = its image

Why -sü and not just -ü? Because when a vowel-final noun takes this possessive suffix, Turkish usually inserts a buffer consonant -s-:

• kapı → kapısı = its door
• araba → arabası = its car
• görüntü → görüntüsü = its image

The vowel ü is chosen because of vowel harmony.

In Turkish noun compounds, the first noun often stays in its bare form, while the second noun gets the possessive suffix.

So:

• akciğer görüntüsü = image of the lung
• not necessarily akciğerin görüntüsü

Both can be correct, but they are slightly different in feel:

• akciğer görüntüsü = a standard noun compound, often used in technical or general descriptions
• akciğerin görüntüsü = the lung’s image, more explicitly possessive

In medical language, the compound form akciğer görüntüsü sounds very natural.

Biraz means a little, somewhat, or slightly.

So:

• biraz bulanıktı = was a little blurry / was somewhat blurry

It softens the description. Compare:

• Akciğer görüntüsü bulanıktı. = The lung image was blurry.
• Akciğer görüntüsü biraz bulanıktı. = The lung image was a little blurry.

It often works like an adverb in English.

Bulanık means blurry, cloudy, or unclear.

In the sentence, bulanıktı is:

• bulanık
  • -tı

That -tı is the past form of the Turkish copula, so bulanıktı means was blurry.

Turkish often attaches the equivalent of was/were directly to adjectives:

• yorgun = tired → yorgundu = was tired
• açık = open/clear → açıktı = was open/clear
• bulanık = blurry → bulanıktı = was blurry

So there is no separate word for was here.

This is because of consonant assimilation and vowel harmony.

The past copula has forms like:

• -dı, -di, -du, -dü
• or -tı, -ti, -tu, -tü

Which one appears depends on the sounds before it.

In bulanık, the final consonant is k, which is voiceless, so the suffix becomes -tı rather than -dı.

Also, the vowel is chosen by vowel harmony.

So:

• bulanık
  • -tı → bulanıktı

Similar examples:

• soğuktu = it was cold
• küçüktü = it was small
• zordu = it was difficult

It is normally written as one word.

In modern Turkish, when the copular past ending attaches to a predicate like this, it is written together:

• bulanıktı
• güzeldi
• hazırdı

So bulanıktı is the standard spelling, not bulanık tı.

Yes, Turkish word order is flexible, but this order is the most neutral and natural.

The basic structure here is:

• Akciğer görüntüsü = subject/topic
• biraz = adverb
• bulanıktı = predicate

A very normal Turkish pattern is to put the main predicate at the end.

So:

• Akciğer görüntüsü biraz bulanıktı. = neutral, standard

Other orders are possible for emphasis:

• Biraz bulanıktı akciğer görüntüsü. = more marked; emphasizes a little blurry
• Akciğer görüntüsü bulanıktı biraz. = possible in speech, but less neutral

For learners, the sentence-final predicate pattern is the safest default.

Because Turkish adjectives do not agree with nouns in gender, number, or case the way they do in many Indo-European languages.

So bulanık stays the same regardless of the noun:

• bulanık görüntü = blurry image
• bulanık fotoğraflar = blurry photos
• görüntü bulanık = the image is blurry

There is no masculine/feminine or singular/plural adjective agreement here.

No. Bulanıktı is already complete and means was blurry.

Adding extra past marking like -ydı again would be incorrect here.

Use:

• bulanık = blurry
• bulanıktı = was blurry

Not:

• bulanıktıydı

Akciğer is roughly pronounced like ahk-jee-ehr.

The letter ğ in Turkish is often called soft g, but in modern standard Turkish it usually does not sound like a strong g. Instead, it often:

• lengthens the previous vowel, or
• creates a smooth transition between vowels

So in akciğer, the ğ is not pronounced like the g in go. The word flows more smoothly between the vowels.

Also note:

• c in Turkish is pronounced like English j
• so akciğer starts with something like ak-jee-...

The Turkish ı is a very important vowel because it does not exist in standard English.

It is:

• unrounded
• farther back in the mouth than i
• somewhat like the vowel in the second syllable of sofa for some English speakers, but not exactly

So:

• i = like ee in see
• ı = a duller, back vowel with no exact English equivalent

In bulanıktı, both ı vowels are this special Turkish ı sound.

It is singular:

• akciğer görüntüsü = the lung image / lung image

If you wanted plural, it would depend on what you mean:

• akciğer görüntüleri = lung images / images of the lungs

Turkish plural in compounds can be a little tricky, but in this sentence the form is clearly singular.

Sometimes Turkish uses a singular noun in a general or category sense, especially in technical language.

So akciğer görüntüsü could refer to:

• a lung image
• a lung scan/image
• even the lung image in a medical context

Depending on context, English may choose lung or lungs, but the Turkish form itself is singular in structure.

That does not always mean the real-world meaning must be strictly one lung only; context matters, especially in medical phrasing.

Yes, that is grammatical.

• Akciğer görüntüsü biraz bulanıktı.
• Akciğerin görüntüsü biraz bulanıktı.

The second version uses an explicit genitive:

• akciğer-in = of the lung
• görüntü-sü = its image

This version can sound a little more specific or explicit. The original compound version is very natural, especially in formal, descriptive, or medical language.

Yes, Turkish often leaves definiteness to context.

So Akciğer görüntüsü biraz bulanıktı could mean:

• The lung image was a little blurry
• A lung image was a little blurry

In real context, especially if a particular image has already been mentioned, English usually chooses the.

Turkish does not use the as a separate word, so learners need to get used to reading definiteness from context rather than from an article.
