Learn Turkish: Ayakkabılarını hemen ayakkabılığa koymalısın. - You must put your shoes in the shoe rack immediately.

The suffix -lIk (which can be -lik, -luk, or -lük depending on vowel harmony) is used here to make a place or container for something. By adding it to ayakkabı (shoe), we get ayakkabılık, which means "shoe rack" or "shoe cabinet".

Wait, if the word for shoe rack is ayakkabılık, why does it have a ğ in this sentence?

Because we are saying "to the shoe rack," we need the dative suffix -a to show direction. When this suffix is added to a word ending in a hard k, the k softens into a ğ (soft g). So, ayakkabılık plus -a becomes ayakkabılığa.

Can you break down all the suffixes on ayakkabılarını?

The root is ayakkabı (shoe). We add -lar to make it plural, then -ın to mean "your". Finally, because "your shoes" is the specific direct object being put away, it needs the accusative suffix -ı at the very end. Altogether: ayakkabı-lar-ın-ı.
