Use of comma punctuation
What are the rules for using a comma? It appears that they are different from English.
Well, punctutation is pretty important in Ukranian, there's many cases but I think it might be enough just to know some basic rules.
When you enumerate (nouns, adj etc.)
When you have 2 or more grammatical foundations (Сонце сяє, і квіти гарні - The sun is shining, and flowers are beautiful)
Before such words as but, therefore, because, as (comparison), and (when it goes to another gram. foundation) etc. - Але, тож (тому), тому що, як, та (і).
When there is a reference to smb / smth (Ти, Маріє, дуже гарна - You are very beautiful, Mary)
Gerund (Ось виходе сонце, сяючи навкруги - Here comes the sun shining around)
Before a word -or- when you say alternative name of the object (Фінляндія, або Країна Тисячі Озер - Finland, or The Land of a Thousand Lakes)
After exlamations like ah, oh, heh, eh, OMG etc. (Ой, зажди - Oh wait)
It might be helpful to start with. There are another principles but it won't be easy to learn them all because even native speakers have to learn it and not everyone deal with them. The thing is this is phylology and you may state one thing in different ways.
