1) When you use "birkaç" before a noun, you can´t use plural suffix.
Few houses: birkaç ev
Fe students: birkaç öğrenci
etc..
2) We commonly use "kelime" instead of "söz" for "word" noun.
3) If something has got a mistake, we say "hatalı".
You are writing with mistakes in Turkish.
Türkçeyi hatalı yazıyorsun.
Yazmak is a dative verb; that´s why I used "-i" suffix. (y is connection character.
thx. By the way, I didn´t know language names weren´t private, sorry.)
