Compound nouns

Grammar form:

In Turkish, compound nouns, also known as nominal compounds are formed when two or more nouns are used together to form a single phrase that acts like a noun. In these phrases, the last word in the phrase is modified or described by the other words in the phrase. While English does not mark these kinds of phrases with any special word ending, most compound nouns in Turkish are marked with the compound noun ending. To make this ending, add a single i type vowel (i, ı, u or ü) to the end of the last word in the phrase. If the last word ends in a vowel, however, you must add an “s” to the end of the word before adding the i-type vowel.

Words ending with Ç, K, P, T

When the last word in a compound noun ends in ç, k, p or t, there is an extra step of changing the consonant before adding the compound noun ending. This step is also needed when adding other word endings that begin with a vowel in Turkish (for example, the ‑a/e ending that means to/toward). If the compound noun ends with ç, k, p or t, the last letter is replaced with another letter, as follows:

  • ç gets replaced with c
  • k gets replaced with ğ
  • p gets replaced with b
  • t gets replaced with d

Exceptions with Ç, K, P, T

But as with most language rules, there are exceptions. And for the compound noun ending, there are lots of exceptions. Firstly, for some words, the last word ends with ç, k, p or t, but the consonant does not get changed to c, ğ, b or d. This happens most often with words that end with the letter t.

Domestic (lit. country interior)

Play

Compound nouns as one word

Sometimes, a compound noun gets used so often that it becomes its own word. When this happens, the compound noun still follows the same rules as a normal compound noun. But it becomes one word instead of two.

Examples

Play
Gök (sky) + kuşak (sash) = gökkuşağı (rainbow)

Buz (ice) +

Play
dolap (cupboard) = buzdola (refrigerator)

Play
Dil (language) +
Play
bilgi (knowledge)
= dilbilgisi (linguistics)

Soy (anscestor) +

Play
ad (name) = soyadı (last name)

Play
Ayak (foot) + kap (container) =
Play
Ayakka (shoe)

Çocuk ayakkabı (kids shoe) ‑ Since ayakkabı here is treated as a single word, an additional compound noun ending can be added, unlike with normal compound nouns which only take one compound noun ending on the last word, regardless of the number of words in the compound noun.

Dropping vowels

In addition to the exceptions above, there is a small number of Turkish words that drop the last vowel in the word when adding the compound noun ending (or any other ending starting with a vowel). However, when you are figuring out the vowel harmony for the word ending, you still have to treat it as though the “dropped” vowel is still there. So, the compound noun ending matches the vowel that was dropped and not necessarily the other vowels in the word. Since most of these exception words follow vowel harmony, it does not matter for most of these cases. But it does matter for words like “vakit” and “akit” (see below).

Examples

Play
İzin (permission)
Play
Oturma izni (residence permit)
Play
Vakit (time)
Play
Namaz vakti (Islamic prayer time)
Play
Karın (stomach)
Play
Koyun karnı (sheep stomach)

Play

Play

Compound nouns with no ending

Also, some Turkish compound nouns do not have any ending on them at all. So they are handled more like how English handles compound nouns: by not marking them in any way. This is especially common for compound nouns where the first noun explains what the second noun is made of.

Examples
Pamuk şeker
Cotton candy

Play
Taş köprü
Stone bridge

Play
Altın kolye
Gold necklace

Play
Tavuk şiş kebap
Chicken shish kabob
(Note that the names of various types of kabobs can also be given the compound noun ending: “tavuk şiş kebabı.”)

Parmak patates
French fries (literally “finger fries”)

Barbekü sos
Barbecue sauce

Play
Erkek çocuk
Boy (literally “man child”)

Play
Soyisim
Last name (literally “anscestor name”)

Compound nouns with repeated consonants

For a handful of words in Turkish, adding a compound noun ending requires repeating the last consonant in the word. When this is the case, the double consonant makes a longer sound than a single consonant would make. So there is a difference both in writing and in pronunciation.

Examples

Play
Metro hat
Metro line

Play
Telif hak
Copyright

Play
Çocukluk Sır
Childhood Secret (book title)

Play
Ücret zam
Wage increase

Play
İncirlik Üs
İncirlik (Military) Base

Compound nouns with repeated vowels

There are a few words in Turkish that end in an i-type vowel but that normally do not take an “s” before the compound noun ending. The most common of these words are “cami” and “bayi.” So if you add the compound noun ending to these words, it turns them into “camii” and “bayii.” However, while this double vowel at the end of the word is seen in writing, it is usually not noticeable in spoken language. Since this exception is very rare, many native Turkish speakers treat them like normal Turkish words and say “camisi” and “bayisi.” This is especially common in every day speech. But it is considered to be incorrect according to the standard grammar rules.

Examples
Sultan Ahmet Camii
Sultan Ahmet Mosque

Play
Tekel bayii
liquor store (literally “single-hand dealer” or “monopoly dealer”)

Evlilik mevzuu
The topic of marriage

Sermaye temetüü
Capital dividend

Words ending in ‑nk

Also, there are a few words in Turkish that end in the letters, “nk” that are treated differently in compound nouns. When these words form a compound noun, the “k” at the end of the word turns into a hard “g” instead of a soft “ğ.” The most common of these exception words is “renk” (color). Since the others are rarely used in compound nouns, “renk” is the main one you need to remember.

Examples

Play
Kahve (coffee) + renk (color) =
Play
kahverengi (Brown)

brown (literally “coffee color”)

Kafa (head) + denk (equivalent) =

Play
kafa dengi (Like-minded)
like-minded (literally “head equal”)

Play
Yılbaşı (New Year’s or Christmas) + fiyonk (bow) = yılbaşı fiyongu
Christmas bow

Cenaze (funeral) + çelenk (wreath) =

Play
cenaze çelengi (Funeral wreath)
Funeral wreath

Compound nouns with the word “su”

Also, if a compound noun ends with the word “su,” the buffer consonant that is used is a “y” instead of the normal “s.”

Examples

Play
Elma suyu
Apple juice (literally “apple water”)
