Kocham Cię (pronounced "koh-hahm tsen-ch")
This is the most common and formal way to say "I love you" in Polish. It's appropriate for romantic partners, family members, and close friends.
Here are some other ways to express love in Polish:
* Kocham ciebie (pronounced "koh-hahm che-bee-eh") - This is a slightly more formal version of "Kocham Cię," but still widely used.
* Kocham Cię bardzo (pronounced "koh-hahm tsen-ch bar-dzo") - This means "I love you very much."
* Bardzo Cię kocham (pronounced "bar-dzo tsen-ch koh-hahm") - This is another way to say "I love you very much."
* Kochanie (pronounced "koh-hahn-yee") - This is a term of endearment that can be used instead of "I love you." It means "darling" or "sweetheart."
Remember to adjust the expression based on your relationship with the person and the context of the situation.
