Learn Turkish: Kimyonu çuval çuval getirdiler ve yığın yığın bıraktılar. - They brought the cumin in sacks and left it in piles.

This is an example of lexical reduplication (ikilemeler). By repeating a noun like çuval (sack) or yığın (pile/heap), you create an adverb that describes how or in what quantity an action was done. Çuval çuval translates to "in sacks" or "sack by sack," and yığın yığın means "in piles" or "heaps upon heaps."

Why does the sentence start with kimyonu instead of just kimyon?

The -u at the end of kimyonu is the definite accusative case suffix. It marks "cumin" as the specific direct object of the action. Because it has this ending, it translates specifically to "the cumin" rather than just cumin in general.

Does kimyonu apply to both halves of the sentence?

Yes! Kimyonu is the direct object for both getirdiler (they brought) and bıraktılar (they left). In Turkish, when two verbs connected by ve (and) share the exact same object, you only need to state the object once at the beginning.

Where does the word yığın come from?

Yığın means a "pile" or "heap." It is formed from the root verb yığmak, which means "to pile up," "to heap," or "to accumulate." Building nouns from verbs this way is very common in Turkish.
