Learn Italian: Vengo alla festa stasera. - I am coming to the party tonight.

In Italian, the present tense (vengo) covers both the simple present ("I come") and the present continuous ("I am coming"). You do not need to translate "am" separately!

Why is the verb vengo when the dictionary says "to come" is venire?

Venire is an irregular verb. Instead of following the normal rules for verbs ending in -ire, the "I" form changes completely to vengo. Since this unique verb form tells us exactly who is acting, the pronoun io (I) is dropped.

Why do we say alla festa instead of a la festa?

When the preposition a (to) meets the article la (the), they merge into one word: alla. Italian requires you to combine these small words to make sentences flow more smoothly.

Where does the word stasera come from?

Stasera means "tonight" or "this evening." It is actually a shortened, merged version of the phrase questa sera (this evening).
