In a sentence
おとうと弟little brotherはげんき元気energeticだ
How it works
は (topic) raises the topic (弟 (little brother)) — “as for my little brother…”. The description 元気 (energetic) is a na-adjective, and here the plain copula だ (is) closes the sentence. That plain だ (is) (instead of polite です (is)) makes it sound casual, like something you’d say to a friend.
