Maciuś

Maciuś is a Polish diminutive form of the name Maciej, which is the Polish equivalent of Matthew. The name Matthew itself has ancient roots, deriving from the Hebrew name Mattityahu, meaning 'gift of Yahweh' (God). In Poland, Maciej has been a popular name for centuries, and Maciuś emerged as a common affectionate or informal variant.

Diminutive forms are very common in Polish culture, often used to express endearment, youth, or familiarity. Maciuś carries this tradition, making it a warm and familiar version of the more formal Maciej. While Maciej is a classic and widely used name, Maciuś is typically reserved for children or within close family and friends.
