I want to describ something which is extraordinary.
Can I write it the other ways?
Or there are some beautiful sentences or words to describ it?
I think your question is lacking context. Is it a good thing or something bad?
Amazing, stunning, terrific, breath-taking is what comes to my mind. Native speakers will give many more.
It is a good thing...sorry I didn't know it was lacking context and I thought extraordinary means good thing originally.
I apprecaited your help. =)
