Purpose clauses (diye)

To express "so that" or "in order to" in Turkish, use the word diye. It frequently follows a verb in the optative or imperative mood to explain the purpose behind a specific action.

so that (purpose)
diye

Third-Person Purposes

When taking precautions so that someone or something else does or doesn't do something, use the third-person imperative form of the verb before diye.

For negative outcomes ("so that it doesn't..."), attach the negative suffix -ma / -me and the third-person imperative suffix -sın / -sin to the verb stem.

They are wearing thick clothes so that the bees do not sting.
Arılar sokmasın diye kalın kıyafetler giyiyorlar.
We are being quiet while approaching the hives so that the bees do not get angry.
Kovanlara yaklaşırken arılar kızmasın diye sessiz oluyoruz.

This exact same structure works for inanimate objects or concepts, such as preventing cold air from entering a hive.

I closed the holes of the hive so that cold air doesn't enter.
Soğuk hava girmesin diye kovanın deliklerini kapattım.

First-Person Purposes

When taking an action so that you or we can achieve something, use the optative mood. For "we", add the suffix -alım or -elim to the verb stem before diye.

We wore white coveralls so that we could cover our bodies.
Vücudumuzu örtelim diye beyaz bir tulum giydik.
We are blowing some smoke into the hive so that we can get the honey easily.
Balı rahat alalım diye kovana biraz duman veriyoruz.

Sentence Structure

The entire purpose clause (Subject + Optative/Imperative verb + diye) typically sits right before the main action in the sentence.
