Questions & Answers about Ontem, vi uma série muito interessante.

Which verb is vi from, and why doesn't it look like a regular past tense verb?

Vi is the "I" form (first-person singular) of the verb ver (to see) in the simple past tense. Ver is an irregular verb, so it doesn't follow the normal rules for past tense endings. Instead, the whole word changes to vi for "I saw". Notice that you don't even need the pronoun eu (I) because the word vi already makes it clear who did the seeing.

In English, "series" has an "s" at the end. Is série plural here?

No, série is singular in this sentence. You can easily tell because it uses the singular feminine article uma (a). If you wanted to talk about multiple series, it would be umas séries.

Since uma série is feminine, why doesn't the adjective interessante have a feminine ending?

Adjectives that end in -e in their base form, like interessante, grande, or inteligente, are usually invariable. This means they are used for both masculine and feminine nouns without changing their ending.

Why does the sentence use muito instead of muita to match the feminine noun série?
