Learn Italian: Il campionato finisce il prossimo fine settimana.

Adjectives that express time, order, or sequence, like prossimo (next), scorso (last), and ordinal numbers, usually go before the noun. This relates nicely to your current lesson: just like you place ordinal numbers before the noun, you do the exact same thing with sequence words like prossimo.

Why does the sentence use il for fine settimana when settimana is a feminine word?

The phrase il fine settimana (the weekend) is masculine because its primary or "head" word is il fine (the end, masculine), not la settimana. Also, because it is a compound noun, it does not change its ending in the plural: i fine settimana simply means "the weekends".

Why is the verb conjugated as finisce instead of just "fine"?

The verb finire (to finish) is an -isc- verb. This means in the present tense, you must insert -isc- between the root (fin-) and the ending for all singular forms and the "they" form. Since il campionato is a third-person singular subject (an "it"), the correct form is finisce.

Does campionato mean "championship" or "season"?
