Questions & Answers about Okuyucular bu kitabın öğretici olduğunu biliyor.
How is the word okuyucular formed in this sentence?
It comes from the verb oku- (to read). We add the agentive suffix -(y)UcU to make okuyucu (reader). Because oku- ends in a vowel, it takes the y buffer. Finally, the plural suffix -lar makes it "readers". This suffix turns verbs into nouns for people who regularly do that action.
The word öğretici uses the same suffix as okuyucu, but here it means "instructive". Can this suffix form adjectives too?
Yes! While the -(y)Icı / -(y)UcU suffix often creates nouns for people or professions (like okuyucu), it frequently forms adjectives that describe what a thing does or the effect it has. Here, öğret- (to teach) becomes öğretici, meaning "instructive" or "educational" when describing the book.
Why is the book in the genitive case (kitabın) instead of just saying bu kitap?
This happens because of the object clause "that this book is instructive". In Turkish, these clauses are built using a genitive-possessive structure. The subject of the embedded clause (bu kitap) takes the genitive suffix (-ın), and the verb (ol-) takes the participle -duk followed by a possessive suffix (-u). Literally, it translates to "readers know this book's being instructive."
