The Spanish word 'mazurca' comes from the Polish word 'mazurka', which refers to a traditional Polish dance in triple time. The Polish term 'mazurka' itself is formed from 'Mazur' (referring to Mazovia, a region in Poland) combined with the diminutive suffix '-ka'. This etymology reflects how the dance originated among the Mazovian people of Poland before spreading to other parts of Europe, including Spain, where it was adapted as 'mazurca'.

There aren't any simpler or more common Spanish words that are etymologically related to 'mazurca', as it's a direct borrowing from Polish that specifically refers to this type of dance.

English speakers might recognize this word as 'mazurka', which is the same dance. English borrowed the word directly from Polish, keeping the original '-ka' ending, while Spanish adapted it to end in '-ca' to better fit Spanish pronunciation patterns. Both refer to the same lively Polish folk dance in triple time that became popular in ballrooms across Europe in the 19th century.
