Compound Nouns (çay bardağı)

Level 2

Noun 1 (Bare) + Noun 2 + [-(s)i] suffix. Used for categories like 'tea glass' (çay bardağı) or 'bus stop' (otobüs durağı).

How It Works

The belirtisiz isim tamlaması (Indefinite Noun Compound) is the primary way Turkish creates new names for objects, places, and categories.

1. The Formula:

2. Suffix Rules:

  • If Noun 2 ends in a consonant, add -ı, -i, -u, -ü (e.g., durak → durağı).
  • If Noun 2 ends in a vowel, add -sı, -si, -su, -sü (e.g., elma → elması).
  • Exceptions: The word su (water) uses a -y- buffer (e.g., meyve suyu). Some Arabic loanwords may use a double 'i' (e.g., sanayii).
  • Apply consonant softening if Noun 2 ends in p, ç, t, or k (e.g., kitap → kitabı).

3. The 'n' Buffer:
If you add a case ending (like locative) to this compound, you MUST insert a buffer -n- before the case suffix. Example: otobüs durağında (at the bus stop).

4. Adjectives:
If you want to describe the compound with an adjective, it must come before the entire unit. Example: eski belediye başkanı (the former mayor).

5. Meaning:
This pattern describes a type or category. Çay bardağı isn't 'the glass belonging to the tea,' but rather a 'tea-type glass.' Even if you are talking about a specific glass (bu çay bardağı), the internal structure remains indefinite because it defines the object's class.

Examples (5)

  1. Her sabah bir fincan Türk kahvesi içerim.

    I drink a cup of Turkish coffee every morning.

    Word by Word: Every morning one cup Turk coffee-its I-drink.

    'Türk kahvesi' is a compound where 'Türk' defines the type of coffee.

  2. Lütfen mutfak masasını temizle.

    Please clean the kitchen table.

    Word by Word: Please kitchen table-its-(n)-accusative clean.

    'Mutfak masası' means kitchen table. Note the -n- buffer before the accusative case suffix.

  3. Hafta sonu çocuk parkına gideceğiz.

    We will go to the children's park on the weekend.

    Word by Word: Week end-its child park-its-(n)-dative we-will-go.

    This sentence contains two compounds: 'hafta sonu' (weekend) and 'çocuk parkı' (children's park).

  4. Portakal suyu taze mi?

    Is the orange juice fresh?

    Word by Word: Orange water-its fresh question?

    The word 'su' (water/juice) is an exception and uses a -y- buffer instead of -s- (suyu).

  5. Yatak odasında bir dolap var.

    There is a wardrobe in the bedroom.

    Word by Word: Bed room-its-(n)-locative one wardrobe there-is.

    'Yatak odası' (bedroom) uses the -n- buffer before the locative suffix -da.

Common Mistakes

  • Forgetting the suffix on the second noun.

    otobüs durak
    otobüs durağı

    In English, you can say 'bus stop' with two bare nouns, but in Turkish, a 'type of' compound like this needs the possessive suffix on the second noun to link them.

  • Forgetting the -n- buffer before case endings.

    sokak lambasıda
    sokak lambasında

    When adding a case suffix to a noun compound, you must use the buffer -n-, not just the case ending alone.

  • Treating the first noun as an adjective.

    Türk kahve
    Türk kahvesi

    Even if the first noun feels like an adjective (like 'Turkish'), if it is a noun in Turkish, the compound rules apply.

Learn This First

To form indefinite noun compounds (belirtisiz isim tamlaması), you need to understand how to apply the third-person possessive suffix -(s)i to the second noun. This requires knowledge of four-way vowel harmony and the use of the buffer consonant -s- for nouns ending in vowels.
