Potocznymi

Potocznymi is the instrumental plural form of the Polish adjective potoczny, meaning colloquial, informal, or everyday. It is used to describe nouns in the instrumental case that are plural, typically when referring to language, expressions, or styles that are informal.

In usage, potocznymi accompanies plural nouns in instrumental form. Examples include phrases such as posłużył się potocznymi wyrażeniami (he used colloquial expressions) or wyrażeniami potocznymi (colloquial expressions). Another common construction is potocznymi słowami (with colloquial words). The corresponding singular forms are potocznym (masculine/neuter) and potoczną (feminine), as appropriate for the noun being described, for example językiem potocznym (colloquial language).

Semantically, the form signals a non-literary, everyday register, often contrasted with literary, formal, or technical styles. It is commonly found in linguistic descriptions, journalism, and writing that aims to convey everyday speech or informal tone.

Etymologically, potocznymi derives from potoczny, itself referring to things ordinary or common in everyday use. The term is part of standard Polish inflection and follows typical adjective agreement rules, with the instrumental plural ending -ymi.
