They basically mean the same thing, but there's a difference in tone: "so big" sounds less formal, and more excited. If I were giving a presentation or writing something important, I'd always say "the ocean is very big." But if I were standing with my friend in front of the ocean and wanted to say how amazing it was, I'd say, "the ocean is so big!"
I appreciate your help. I have learnt a lot from native speakers as you. Thanks again.
If you say "okyanus çok büyük", does that convey more of an informal and passionate sort of tone whereas "okyanus çok büyüktür" would be more of a bland, formal statement of the facts?
It usually does. But here i think it would support -dir's function if 'okyanus' would be plural. Because you don't talk about a specific ocean and if you don't say 'oceans in general' it sounds incomplete somwhat.
I do not understand why can't we say An ocean is very big?Why do we use The here?
"okyanus" is for huge seas, and there are only 3 of them, Hint, Pasifik, Atlas. The others are "deniz" (Meditterrenean, Black sea etc)
So, "okyanus" is basically ocean (and looks like a loan from Greek) and "deniz" is basically "sea", yeah?
