"That writer is not writing books anymore."
Translation:O yazar artık kitap yazmıyor.
Turkish is quite flexible in speech, but Duo generally keeps the verb at the end of the sentence (or each clause, if there are two). There are often more possibilities in the real world, but keeping that in mind will help you get through each lesson here :-)
Unfortunately, Duo limits the number of possible answers that contributors are able to add... so they (and we) are limited to standard written word-order.
Demonstrative pronouns - "İşaret zamirleri."
Bu - This(one) Şu - This(one), that(one) O - That(one) Bunlar - These. Şunlar - These, those. Onlar - Those.
Enlightened note: The plural form of the demonstrative pronouns take the plural suffix "-lar" & the letter "-n" is added before the suffix "-lar."
Usage of the pronoun "Şu" The demonstrative pronoun "şu" (this or that) & its case forms are used to show the object which is a little further away.
Example: Şuna bak! (Look at this!) ---> Dative case, singular.
Şunlara bak! (Look at these!) ---> Dative case, plural.
Usage of the pronoun "O." The pronoun "o" is used for both personal (he, she, it) & as a demonstrative pronoun.
The demonstrative pronoun "o" (that) has the same meaning as "şu."
Example: Arkadaşım ondan aldı. (My friend bought from that.) ---> Ablative case, singular.
Arkadaşım onlardan aldı. (My friend bought from those.) ---> Ablative case, plural.
Şu yazar artık kitap yazmıyor. - Correct.
O yazar artık kitap yazmıyor. - Correct.
