So, "tersebut" meant "mentioned" in a previous sentence and simply the definite article "the" here.
'tersebut' is often translated as the definite article 'the', although it's actually not a definite article.
It's used to refer to something that was mentioned earlier.
If it should be translated into one single word in English, I would choose a word like 'aforementioned' .
Here is an example based upon a news article.
The title of the article :
Kamis 06 September 2018, 03:44 WIB
Penyakit Misterius Penumpang Emirates di NY, 10 Orang Dibawa ke RS
WIB = Waktu Indonesia Barat (West Indonesia Timezone)
NY = New York
RS = Rumah sakit (hospital)
I'm sure you can read and understand the title.
This is one of the paragraphs in that article :
Pesawat tersebut mendarat di Bandara Internasional JFK, New York pada Rabu (5/9) pagi waktu setempat sekitar pukul 09.00.
'Pesawat tersebut ..' is the start of the sentence.
'tersebut' refers to the plane that has been mentioned throughout the article.
This is how the word 'tersebut' is normally used.
To refer to something that was already mentioned, to connect the sentences, to make the sentences flow.
However, it's almost always translated as 'the'.
So, "tersebut" meant "mentioned" in a previous sentence and simply the definite article "the" here. Is there an active verb with this -sebut root that could clarify its use?
'sebut'(base word; verb)
'menyebut' (active verb)
'menyebutkan' (active verb)
'menyebut' = 'to mention, to give a name, to cite, to call, to say', the verb can have slightly different meanings.
"Tini menyebut anjingnya dengan nama Srigalak'
'Tini mentions her dog Srigalak'
('mentions = gives her dog the name')
'Tini menyebut nama Tono saat dia tidur'
Tini mentions Tono's name when she slept'
('mentions = calls out his name')
'Tini menyebut kata-kata itu satu per satu'
Tini mentions the words one by one.
('mentions = cites, says outloud')
'Jangan sebut masalah itu kepada Tono'
'Don't mention this problem to Tono'
Does this sentence use bukan because the second half is really a noun phrase?
Yes, correct, it's a noun phrase.
"milik" is a noun.
"milik" = kepunyaan (property,ownership)
'Buku ini milik saya' = This book is my property = This book is mine
Buku ini bukan milik saya = This book is not my property = This book is not mine.
'bukan' is used to negate the noun phrase.
'tidak' is used to negate the verb, like in the following sentence :
Saya memiliki buku ini = I own this book = I have this book.
Saya tidak memiliki buku ini = I do not own this book = I do not have this book.
