It's important to note that the "Cię" at the end is a shortened form of "Ciebie," which is used to emphasize the directness and intensity of the feeling.
You can also say "Kocham Ciebie" for a slightly more formal or emphatic version.
Here's a breakdown of the word:
* Kocham: I love
* Cię/Ciebie: you
This phrase is commonly used for romantic love, but can also be used to express deep affection for family and friends.
