-ler / -lar

Kardeşler, Kayalar, Demirler: what these surnames share is the plural suffix at the end. Turkish has two shapes of it, -lar and -ler, and vowel harmony picks between them. After a back vowel the suffix is -lar: kaya ‘rock’ gives Kayalar, aslan ‘lion’ gives Aslanlar. After a front vowel it is -ler: demir ‘iron’ gives Demirler, çelik ‘steel’ gives Çelikler. The consonant never changes. The suffix always begins with l.

Its basic job is to mark plurality. In everyday speech it also names a household. “Yılmazlar geldi” means ‘the Yılmazes have arrived’, the Yılmaz family as a group. In surnames the suffix usually carries this second sense. Yılmazlar reads as ‘the Yılmaz family’. Demirler, Çelikler and Aslanlar follow the same pattern: an existing name turned into a collective.

Kardeşler works a little differently. Here the suffix attaches to a kinship word, and the result means ‘siblings, those who are brothers or sisters to one another’. The weight of the meaning still sits in the root. The suffix only adds the idea of a group. For that reason the site files these surnames by the meaning of the root. Kayalar joins the mountain-and-rock surnames, Aslanlar the predators. The suffix itself is recorded in the suffix field.

One caution matters. Forms such as Kayalar and Hacılar are also common as village names. Whether a given record refers to a place or to a family can only be settled from a source. The shape of the word alone does not justify a place-name reading.

The most frequent false friends are verbs. Güler is not a plural at all. It is the aorist of gülmek ‘to laugh, smile’ and means ‘(one who) smiles’. Söyler, from söylemek ‘to say’, and Dinler, from dinlemek ‘to listen’, behave the same way. In these words the l belongs to the verb stem and the final -r is the aorist ending. İşler usually belongs to işlemek ‘to work, process’. Kiler is a separate noun meaning ‘pantry’. Hünkâr is a title of Persian origin with no plural in it.

In short, -lar/-ler adds no new meaning of its own. It turns a name or word that already exists into a group. A sound analysis first asks whether the root stands on its own as a noun or name. It then tests whether the whole form could be a verb. When both answers are clear, the suffix can be split off with confidence.
