/kajɯnbiɾadeɾ/from spelling rules
The Turkish phrase for brother-in-law is kayınbirader.
kayınbirader is used specifically to refer to the brother of one's spouse.

What does it mean word for word?

The word is a compound of kayın (related to in-laws) and birader (brother).

Which one should you use?

While kayınbirader specifically refers to the brother of one's spouse, the term enişte is used for a sister's husband.

How does it change in a sentence?

To say my brother-in-law, you add the possessive suffix -im to the end of the word to form kayınbiraderim. To make the word plural, add the suffix -ler to the end to form kayınbiraderler.

How do you pronounce it?

The pronunciation is /kajɯnbiɾadeɾ/. It is composed of the sounds: /k/ as in [c]ore, /j/ as in [y]es, /ɯ/ somewhat like ribb[o]n, /n/ as in [n]ot, /b/ as in a[b]out, /i/ as in cr[ee]k and /ɾ/ as in AmE a[t]om.

Did you know?

  • The word birader in kayınbirader is borrowed from Persian. In casual modern Turkish, birader is often used as a slang term meaning 'dude' or 'bro' among friends regardless of kinship.
  • In traditional Turkish culture, a kayınbirader might be addressed using the respectful title abi (older brother) instead of his name to show familial respect.
  • Because Turkish is an agglutinative language, you can add multiple suffixes to kayınbirader to mean 'my brothers-in-law's children' in a single long word.

Examples in context

  • Kayınbiraderim yarın bize gelecek.
    My brother-in-law is coming to visit us tomorrow.
  • Kayınbiraderin ne zaman İstanbul'a taşındı?
    When did your brother-in-law move to Istanbul?
