Learn Turkish: Giyim bölümünü gösterir misin? - Would you show the clothing section?

The first -ü creates the noun compound "clothing section" (giyim bölümü). The second -ü is the accusative case marker, which is required because the "clothing section" is the specific direct object of the verb "to show" (göstermek).

What is the letter -n- doing in bölümünü?

It is a buffer letter. Whenever you attach a case suffix (like the accusative -ü) to a word that already ends in a third-person possessive or compound suffix (like the first -ü in bölümü), you must use -n- as a bridge between them, rather than the standard -y-.

Why is the verb gösterir misin in the aorist (simple present) tense instead of gösteriyor musun?

In Turkish, the aorist tense (the -ir in gösterir) is frequently used to make polite requests, much like asking "Would you...?" or "Could you...?" in English. Using the present continuous (gösteriyor musun) would sound more like a literal question about current actions: "Are you showing it right now?"

I usually see clothes translated as kıyafet or giysi. Why use giyim here?
