"The wind is cold today."
Translation:Anuanu ka makani i kēia lā.
I don't understand when "i" is necessary in these sentences. I'm very confused & frustrated.
The "i" often marks common nouns when they act as objects (direct or indirect).
To find information on grammar, search for the sentence structure " po'o piko 'awe." The search result, for me, showed sites with class lessons on that type of grammar and more.
