wyraeniami

Wyrażeniami is the instrumental plural form of the Polish noun wyrażenie, meaning expression, phrase, or way of expressing something. The form appears when the noun is used in the instrumental case, typically to indicate the means by which something is done or the expressions used as a tool. In writing that omits diacritics, wyrażeniami is sometimes rendered as wyrazeniami.

In linguistics and semantics, wyrażenie denotes a unit of meaning formed by a sequence of words or symbols. It can refer to a literal phrase, an idiom, a collocation, or a mathematical or logical construct. In mathematics and logic, wyrażenie describes a syntactic construction that yields a value or truth-functional result, such as an algebraic expression or a logical formula. The term thus spans natural language usage and formal notation.

Grammatically, wyrażenia is the nominative plural, used when the expressions are the subject of a sentence. Wyrażeniami is the instrumental plural, used with verbs that require the instrumental case, for example: posługujemy się wyrażeniami (we rely on or use expressions).

Common considerations include the distinction between wyrażenie as a general term for a unit of meaning and wyrażenia as its plural nominative form. The form wyrażeniami is standard in correct Polish usage, while wyrazeniami without the diacritic is a misspelling in formal contexts.
