Rolkach

Rolkach is the locative plural form of the Polish noun rolka. Rolka is a feminine noun with several senses, most commonly referring to a small cylindrical object such as a roll of tape or fabric, or in everyday speech to roller skates. The form rolkach is used after prepositions to indicate location or the context of an action.

In ordinary use, rolkach appears especially in phrases describing skating, as in jeździć na rolkach, meaning to ride on roller skates. For example, W parku spacerowałem i jeździłem na rolkach translates to I was skating in the park. The locative plural can also appear in other contexts where a plural cylindrical item is discussed after a preposition, though in practice many speakers rely on more specific phrases like rolki (the skates themselves) or rolls of a material.

Etymology traces roka back to the root rol- meaning to roll, with the common diminutive suffix -ka forming the noun rolka. The locative plural formation is a standard feature of Polish grammar, not a separate lexical item.
