Kaya-

Kaya is Türkiye’s second most common surname. TÜİK ADNKS 2025 records 899,722 bearers. The word also appears in many compounds. In names such as Karakaya or Akkaya it stands at the end and is covered on the -kaya page. This page looks at surnames where kaya comes first.

The Güncel Türkçe Sözlük defines kaya as ‘a large, hard mass of stone’. It is a full noun, not a suffix, so vowel harmony does not affect it. When the second element begins with a vowel, the final vowel of kaya is not dropped. Kayaalp writes two *a*s side by side, and in Kayaer a meets e.

In first position kaya behaves like an adjective. It adds the sense ‘firm as rock, unshakeable’ to the second element. The centre of meaning is the second element. Kayaalp is ‘a hero firm as rock’ and Kayaer ‘a man firm as rock’. Kayahan reads as ‘a khan strong as rock’ and Kayacan as ‘a soul firm as rock’. Kayatürk follows the same pattern.

Kayabaşı has a different structure. Two nouns are linked by a possessive suffix: kaya + baş + -ı, ‘the top of the rock’. This describes a place, and it occurs in many village and locality names. Choosing such a word as a surname can be explained as the use of a place name or landscape term; it says nothing about where the bearers come from.

In Kayaoğlu, kaya is followed by -oğlu ‘son of’. Since Kaya is also used as a personal name, the surname resembles those built on a father’s name. Article 6 of the 1934 Soyadı Nizamnamesi states that a surname is used either on its own or together with “(oğlu)”. Kayaoğlu is one of the forms that fit this pattern.

Some names look like compounds at first sight but are not. Kayalar is the plural of kaya; the final -lar is the plural suffix. Kayalı is derived with -lı and means ‘rocky, having rocks’; it can also be a place name. Kayacık is a diminutive and the name of many villages. None of these three is counted among the Kaya- compounds.
