"The boy is his brother."

Translation: Το αγόρι είναι ο αδελφός του.

[ShaoxuanLi]

This is a multiple choice question for me, why is Ο αγόρι είναι ο δικός του αδερφός. incorrect?

[HongNhiNhi]

Because the gender of the article for the word '' αγόρι΄΄is not correct, it must be the neuter ''το''.

You can easily get one, just check for instructions in the first unit tips (https://www.duolingo.com/skill/el/ABC/tips-and-notes) or the Greek forum (https://forum.duolingo.com/topic/936/hot) sticky post for the keyboard (see THE MODERN GREEK ALPHABET and HOW TO GET THE GREEK KEYBOARD) or the internet (search engine of your choice)! :)
