Fuarda herkes yeni ürünleri inceliyor.

• fuar means “fair” (as in a trade fair or exhibition).
• The suffix -da is the locative case, indicating “at” or “in.”
• By vowel harmony, since the last vowel in fuar is a (a back vowel), we use -da (not -de).
• Because r is a voiced consonant, it stays d (voiceless-after-voiceless rule would turn it into -ta if fuar ended in a voiceless consonant).
Result: fuarda = “at the fair.”

• herkes means “everyone” or “everybody.”
• It refers collectively to all people but is grammatically singular.
• You never add -ler to herkes because it already implies “all people” in one word.

• -i is the accusative case suffix, marking a definite direct object (“the new products”).
• In Turkish, if you talk about specific or known items, you use the accusative: yeni ürünleri = “the new products.”
• If it were indefinite/general, you’d say Fuarda yeni ürünler inceleniyor (“new products are being examined,” with no -i).

1. Start with the noun ürün (product).
2. Add plural -ler → ürünler (“products”).
3. Look at the last vowel of ürünler, which is e (a front vowel).
4. Add accusative -i (front vowel version) → ürünler
   • i = ürünleri (“the products” as a definite object).

• Root: incele- (“to examine/inspect”).
• Suffix: -iyor (present continuous tense).
• Person/number: for 3rd person (he/she/they), you use -iyor with no extra ending.
Putting it together: inceliyor = “he/she/they are examining.”

• In Turkish, the present continuous suffix -iyor already covers 3rd person singular and plural.
• You do not add -lar on the verb for plural subjects.
• The plurality comes from the subject word herkes, so inceliyor remains unchanged.
