hello,
I think this means 'good night' but am not sure. I couldn't find the 2nd word in the online dictionary... hoping someone can help! Many thanks!

iyiki vars*n

*=special character on sms message received.

İts is

İyiki Varsın i guess

İt's like stay well ,be well , something like that

It is "iyi ki varsın" and means "I'm glad there is you".

Canlı,
"iyi ki" means fortunately and "varsın" means "you exist". It is a conjugation of 'var', like 'var', 'varım', 'varsın', etc. and smillarly we have 'yok', 'yokum', 'yoksun'.

Evet erdinc,

Wb first long time no see

well,İ thought iyi ki as like goodness
And vaesın as you said is you exist

So i thought it would be like a wish for him or her to exist or stay in good

thank you Canli & Erdinc for your help... it is appreciated.
