Translation - Turkish-English - merhaba,çok güzelsin.

hello, you are very beautiful.

selam burcuk,

now i saw that i translated it wrong, thanks for correction

Instead of 'nice',it'd be better to use 'beautiful'.

"nice" yerine "beatiful" kullanılmalı bence

güzel could be "beautiful" but also "nice" or "pretty" and many other synonymous.
