Learn Turkish: Deli büyücü tehlikeli bir kehanet yazacakmış. - They say the crazy sorcerer will write a dangerous prophecy.

The verb yazmak (to write) first takes the future tense suffix -acak, making yazacak (will write). Then we add the inferential suffix -mış. This -mış acts as a hearsay marker, adding the meaning of "I heard", "reportedly", or "they say". Together, yazacakmış means "I heard that he will write" or "supposedly he will write".

Why is the word order tehlikeli bir kehanet instead of bir tehlikeli kehanet?

In Turkish, when a noun has both a descriptive adjective and the indefinite article bir (a/an), the adjective almost always comes first. The standard pattern is [Adjective] + bir + [Noun]. So "a dangerous prophecy" must be written as tehlikeli bir kehanet.

How is the word büyücü (sorcerer) formed?

The root is büyü, which means "magic" or "spell". The suffix -cü (which changes to -cı, -ci, or -cu depending on vowel harmony) is a maker/profession suffix. It attaches to a noun to describe a person who makes, sells, or practices that thing. So, büyücü literally means "magic-maker".
