Learn Hardcore Russian: Каждый покупатель берёт корзину, выбирает товар и идёт к кассиру. - Every customer takes a basket, selects a product, and goes to the cashier.

Каждый means each (emphasizing individuals one by one), while все means all as a group. Here the sentence describes what every single customer does in turn, so каждый покупатель is more precise than все покупатели.

What case is корзину in берёт корзину, and why?

Корзину is in the accusative case (feminine singular). With verbs of taking or grabbing like брать (to take), the direct object is put into the accusative to show what is being taken.

Why is берёт in the imperfective aspect instead of a perfective like взял or возьмёт?

Imperfective verbs (берёт) describe habitual, repeated or ongoing actions. The sentence outlines a typical routine in the store. A perfective form (взял, возьмёт) would highlight a single completed action or future result, changing the general-routine meaning.

Why is товар in выбирает товар in the accusative case?

Товар is the direct object of выбирать (to choose/to pick), so it must be in the accusative. Since товар is an inanimate masculine noun, its accusative form is identical to its nominative.

Why does идёт к кассиру use к plus the dative case, resulting in кассиру?

The preposition к (toward) always takes the dative case to express movement toward a person or place. The dative of кассир is касси́ру, hence идёт к кассиру means “goes up to the cashier.”

How do the commas and the conjunction и work in this sentence?

The three verbs are homogeneous predicates sharing one subject (каждый покупатель). In Russian, you separate them with commas and place и only before the last item, just like in an English list: “takes…, chooses…, and goes….”

What tense are the verbs, and what does the present tense imply here?

All verbs (берёт, выбирает, идёт) are in the present tense. In Russian, the present tense can describe habitual actions, general truths, or instructions—so this sentence states the usual sequence every customer follows.

Why are there no articles like “a” or “the” before the nouns in Russian?

Russian does not have articles. Definiteness or indefiniteness is conveyed through context, word order, or additional words, so you simply use корзину, товар, кассиру without any article.

Is the word order каждый покупатель берёт корзину… fixed in Russian?

The default Subject-Verb-Object order is neutral and clear here. Russian word order is quite flexible though—you could rephrase for emphasis (e.g. Корзину каждый покупатель берёт первой), but the given sequence is the most straightforward.
