"I have five cousins."

[clgibbons]

If cousins is plural, why is this not kuzenlerim?

[AlexinNotTurkey]

The plural suffix is not used with numbers! :)

[clgibbons]

Thanks. I had not noticed this before!

You have to use only one "making plural" word or plural suffix in a phrase. You can't use both together.

Benim beş kuzenim var. (beş is a number and numbers are making plural words)

Benim çok kuzenim var. (çok, fazla, epey, birçok are making plural words)

Benim kuzenlerim var. (-ler plural suffix)

"Beş tane kuzenim var" should also be correct, surely?
