Questions & Answers about Все друзья гуляют в парке.

What does Все mean and how is it used here?

Все means “all” when referring to multiple people or things. Here it’s a plural quantifier agreeing in number and case with друзья (friends) in the nominative plural, so Все друзья = “All (the) friends.”

What’s the difference between все and всё?

все (no diacritic) is plural “all” (e.g. все студенты = “all the students”).
всё (with ё) is neuter singular “everything” (e.g. всё хорошо = “everything is fine”).

Why is друзья used instead of други?

друзья is the correct, irregular nominative plural of друг (“friend”). Some masculine nouns change their root vowel and add -ья in the plural (друг → друзья, брат → братья). други is archaic or poetic and isn’t used in everyday speech.

Why isn’t there an article before друзья (“the friends”)?

Russian doesn’t have articles like English “a” or “the.” Definiteness is understood from context. If you want to say “my friends,” you’d use a possessive: мои друзья.

Why is гуляют in this form, and how is гулять conjugated?

гуляют is the 3rd person plural present tense of гулять (“to stroll, take a walk”). It follows the 1st-conjugation pattern:
я гуляю, ты гуляешь, он/она гуляет, мы гуляем, вы гуляете, они гуляют.

What’s the nuance of гулять compared to ходить or идти?

гулять implies walking as a leisure activity or strolling without a fixed destination.
идти (unidirectional) / ходить (multidirectional) focus on movement from point A to B.

Why is в парке in the prepositional case, and how do you form it?

After в meaning “in” (location), Russian uses the prepositional case. For most masculine nouns ending in a consonant, add -е:
парк → в парке.

Can I change the word order? For example, В парке все друзья гуляют?

Yes. Russian word order is flexible. Placing в парке first emphasizes the location; the basic meaning stays the same.

How is the stress placed in парке?

On the only vowel а (carrying over the stress from парк): пáрке.

How does все decline in other cases?

As a pronoun it goes:
Nominative – все
Genitive/Accusative – всех
Dative – всем
Instrumental – всеми
Prepositional – всех
