wyraeniach

Wyrażenie is a Polish noun meaning expression or phrase. The form wyrazeniach is the locative plural (with diacritics it is wyrażeniach). This form appears after prepositions such as w or na, for example in phrases like in wyrażeniach idiomatycznych. In ASCII texts or simplified orthography the diacritics are omitted, producing wyrazeniach.

In linguistic usage, wyrażenia refer to units of meaning that consist of a sequence of words and function as a single semantic unit. They include phrases, collocations and idioms, which cannot always be understood from the meanings of their individual words. For instance, idiomatic wyrażenia convey figurative meanings that differ from their literal components.

In mathematics and logic, wyrażenie denotes a syntactic combination of symbols that can be evaluated, such as algebraic expressions like 2x + 3 or a^2 + b^2. In computer science, wyrażenia regularne (regular expressions) are a formal language used for pattern matching and text processing.

In everyday Polish, wyrażenie can also mean an expression of emotion or thought, such as facial expressions (wyraz twarzy) or statements made in speech (wyrażać myśli). The locative plural wyrażeniach appears in contexts discussing these expressions or their categories, for example "w wyrażeniach idiomatycznych" or "w wyrażeniach matematycznych."
