How it works

English links cause to effect with a conjunction that opens the second clause: 'I did not come because I was ill'. Turkish does it with a suffix at the end of the first clause, and that clause goes first — the rewiring that defines the B1 level.

Cause. The native way is the participle -dık with a possessive tail plus the postposition için: Hasta olduğum için gelmedim — 'my being ill for, I did not come'. The subordinate clause goes FIRST, and the link sits at its END. The familiar çünkü gives the same thought inside out: Gelmedim, çünkü hastaydım — second clause, comma, conjunction at the front, exactly as English would build it. Both are correct, but the first sounds Turkish and the second sounds translated.

Cause can also be introduced by postpositions, and they come tinted. -den dolayı is neutral: kar yağdığından dolayı. yüzünden blames: senin yüzünden geç kaldım — I was late because of you, and it is your fault. sayesinde thanks: senin sayesinde başardım — thanks to you, it worked. They stand AFTER the word, not before it: the English 'because of' leads, the Turkish yüzünden trails.

Purpose. Here is the fork where the most mistakes happen. If ONE person acts — the infinitive plus için: Bilet almak için sıraya girdim — I joined the line in order to buy a ticket. If the one who acts and the one for whose sake are DIFFERENT — the optative on -sin plus diye: Çocuk uyusun diye ışığı kapattım — I turned off the light so that the child would fall asleep. Saying uyumak için here would mean I am the one planning to sleep.

Negative purpose is built with the same diye: unutmayayım diye not aldım — I took notes so as not to forget. The bookish versions of both — -mek amacıyla and -mek üzere — you will meet in notices; in conversation they sound heavy.

How the rule settles in your head

A rule is not memorized from an explanation. It is memorized from an attempt to use it and a mistake — that is why the app delivers it mixed in with words, not as a separate lesson: it resurfaces exactly where you forgot it.
