Iya, hampir betul, tetapi jika nama profesi adalah jamak, tidak artikel. Tidak ada "the".
He is an architect: Dia (seorang) arsitek.
They are architect: Mereka arsitek.
He is an official (Tunggal). They are officialS. (Jamak)
"Official" = kata benda = nama profesi.
Dia pejabat. He works for the government.
He is official (Tunggal). They are official (Jamak)
"Official" = kata sifat = tidak "s".
@Awaldi I disagree. We can search every meaning for a sentence, regardless of the chapter. It's a good way to understand sentences, words and English better. Any people who do this will make huge progress in English, really huge.
His question is really interesting. Why so many downvotes and no real reply?
