Learn Polish: Pozdrawiam Was z wakacji! - Greetings from my holiday!

In Polish correspondence, such as postcards, emails, or text messages, it is standard practice to capitalize pronouns referring to the recipient. Writing Was instead of was shows respect and personal attention, even in casual messages to friends.

The English translation says "Greetings", but isn't pozdrawiam a verb?

Yes, pozdrawiam literally means "I greet" or "I am greeting". While Polish does have a noun for greetings (pozdrowienia), using this first-person verb is the most natural and frequent way to send regards or say "Greetings from..." in a message.

Why is the word for holiday, wakacji, in the plural form here?

The base word wakacje (holiday or summer vacation) is a plural-only noun in Polish, meaning it never takes a singular form. Because it follows the preposition z (which means "from" in this context), it must take the genitive case, giving us the genitive plural form wakacji.

Why doesn't the Polish sentence include the word for "my" (moich)?

Polish frequently drops possessive pronouns like mój (my) when the context makes ownership completely obvious. Since the speaker is the one sending the postcard or message, it is automatically understood that they are on their own holiday.
