Learn Hardcore Russian: Твой сад красиво цветёт весной. - Your garden blooms beautifully in spring.

Твой is a possessive pronoun meaning your (singular, informal). It must match сад in gender, number, and case. Since сад is masculine singular nominative, we use the masculine nominative form твой (not твоя, твоё, or твои).

Why is there no article (the/a) before сад?

Russian does not have articles. You simply use the noun сад on its own to say “garden,” and definiteness or indefiniteness is understood from context.

What case and number is сад in, and why?

Сад is in the nominative singular because it is the subject of the sentence (the thing doing the blooming).

What is the form of цветёт, and what aspect does it express?

Цветёт is the 3rd person singular present tense form of the imperfective verb цвести (“to bloom/flower”). The imperfective aspect indicates an ongoing or habitual action—here, that the garden blooms (habitually) in spring.

Why is the letter ё used in цветёт, and how does that affect pronunciation?

The letter ё represents the sound /jo/ and always carries the stress in a word. In цветёт, stress falls on ё, so you pronounce it [tsvʲɪˈtʲot]. In many texts the dots over ё are omitted (printed as е), but you still say /jo/.

What part of speech is красиво, and why not красивый?

Красиво is an adverb meaning “beautifully.” It modifies the verb цветёт. Красивый is an adjective (“beautiful”) and would only modify a noun (e.g., красивый сад).

What case is весной, and why does Russian use that case to say “in spring”?

Весной is the instrumental singular of весна (spring). Russian often uses the instrumental case (without any preposition) to express the time when something happens: утром (in the morning), летом (in summer), весной (in spring).

Is the word order fixed? Could I say Весной твой сад красиво цветёт?

Word order in Russian is relatively free. Moving весной to the front—Весной твой сад красиво цветёт—is perfectly correct and simply shifts emphasis onto “in spring.”
