Learn Hardcore Turkish: Markette ürün eksikliği var. - There is a shortage of products in the market.

Markette is the locative form of market (“grocery store”). The locative case (meaning “in/at”) uses the suffix -de/-da, but because market ends in the voiceless consonant t, the suffix appears as -te. Furthermore, the original t in market and the d of the suffix assimilate to tt, giving markette: “in the store.”

Why is there no equivalent of the English article “a” or “the” before ürün?

Turkish does not have separate indefinite or definite articles like “a” or “the.” A bare noun like ürün can mean “a product,” “the product,” or “product” in general, depending on context. If you want to emphasize “a specific product,” you would use the accusative suffix -ü (e.g. bir ürünü “a certain product”).

What is the difference between the adjective eksik and the noun eksiklik?

Eksik is an adjective meaning “missing” or “deficient.”
Eksiklik is the noun “deficiency,” “lack,” or “shortage.”
In ürün eksikliği var, we need the noun “shortage,” so we use eksiklik.

Why does eksiklik take the suffix -i (→ eksikliği) before var?

In existential sentences with var (“there is”), when the thing that exists is itself a condition or quantity (like a shortage), Turkish often adds a third-person possessive suffix to the noun. So eksiklik + -i → eksikliği, literally “its shortage,” but idiomatically “a shortage exists.” This suffix is required in such constructions and does not imply ownership by a person.

Why is var at the end of the sentence, and could I use yok instead?

In Turkish existential clauses, var (“there is/are”) or yok (“there isn’t/aren’t”) always comes after the noun phrase.

var affirms existence (“there is a shortage”).
yok denies it (“there is no shortage”).
So you could say Markette ürün eksikliği yok to mean “There is no product shortage in the store.”

What’s the difference between ürün eksikliği var and eksik ürün var?

Ürün eksikliği var = “There is a shortage of products” (a general lack of stock).
Eksik ürün var = “There is a missing/defective product” (referring to a specific item that is incomplete or absent).

Could I instead say Markette ürünler eksik?

Yes. Markette ürünler eksik literally means “Products are missing in the store.” It’s more like “some items are out of stock.” That phrasing uses eksik as an adjective modifying the plural ürünler, whereas ürün eksikliği var emphasizes the abstract concept of a “shortage.”
