Learn Romanian: Pisica are un ochi albastru.

In Romanian, the word for "the" (the definite article) attaches to the end of the noun instead of being a separate word before it. The base word is pisică (cat). By changing the final -ă to -a, you get pisica (the cat).

Ochi ends in an "-i". Doesn't that usually mean a word is plural?

Often, yes! An "-i" at the end of a masculine noun usually marks a plural. However, ochi is a tricky exception because its singular and plural forms are exactly the same. We know it means "one eye" in this sentence because it is paired with the singular words un (a/an) and albastru (blue).

Why is the color word albastru placed after the noun ochi?

Unlike in English, where we say "a blue eye", Romanian descriptive words (adjectives) almost always come right after the noun they describe. So, the sentence translates word-for-word as "The cat has an eye blue".

Is the verb are a regular verb?

No, are (has) comes from the highly irregular verb a avea (to have). It is the form used for "he, she, or it has". Because this is one of the most common verbs in Romanian, you will just need to memorize its forms early on, like am (I have) and ai (you have).
