Learn Hardcore Romanian: Apa este bună.

Apa is the word for “water.” In Romanian, definite articles are attached to the end of the noun. The root apă means “water” (indefinite), and the suffix -a makes it “the water.” So apa = “the water.”

Why do we say este instead of just e?

Este is the full form of the verb “to be” in the present tense (third person singular). Colloquially, Romanians often shorten it to e (e.g., Apa e bună), but este is the more formal or standard written form.

Why does bună end with -ă instead of -ă? I thought adjectives end in -ă for feminine—so why is it the same letter?

It may look identical, but there are two different letters:

ă (the vowel pronounced like the ‘a’ in “about”)
a (the standard “a” sound)
In bună, the ending is the vowel ă, marking the feminine singular form of the adjective bun (“good”).

Why is the adjective bună placed after the noun, instead of before, like in English?

In Romanian, descriptive adjectives typically follow the noun they modify. So you say apa bună (“the good water”). When you include the copula este, it becomes apa este bună: literally, “the water is good.”

Is this sentence indefinite or definite?

Definite. Because the noun apa has the definite article attached, the sentence means “The water is good,” not just “Water is good.” If you wanted to say “Water is good” in general (indefinite), you could use Apa e bună with a less specific nuance, but in practice apa almost always carries that “the” meaning.

How would I turn this statement into a question (“Is the water good?”)?

You have two common options:

Keep the same word order and raise your intonation: Apa este bună?
Invert verb and subject: Este apa bună?
Both are perfectly acceptable and understood as “Is the water good?”

If I wanted to say “The water isn’t good,” how would I negate the sentence?

Place nu before the verb: Apa nu este bună.
Literally: “The water not is good.”

What about masculine or plural forms? How would it change?

Masculine singular: apa este bun (rare, because apă is feminine)
Feminine plural (for a feminine noun): adjective ends in -e (e.g., fetele sunt bune)
Masculine plural: adjective ends in -i (e.g., băieții sunt buni)

How do I pronounce the full sentence?

Break it down:

Apa = [ˈa.pə] (A-puh)
este = [ˈes.te] (Es-teh)
bună = [ˈbu.nə] (Boo-nuh)
Put it together with natural Romanian rhythm: [ˈa.pə ˈes.te ˈbu.nə].
