Neologismem

Neologismem is the instrumental singular form of the noun neologismus (neologism) in Czech and related Slavic languages. In linguistic writing, neologismem is not treated as a separate concept; it is simply the grammatical form used when referring to a neologism within a sentence. For example, a Czech sentence might say that a word has become neologismem.

A neologism is a newly coined word or expression that enters a language and gains use. Neologisms arise through coinage, semantic extension, calques, or borrowing from other languages, and they can belong to different word classes. Their acceptance depends on factors such as frequency, breadth of use, and inclusion in dictionaries or standard usage. Distinctions are often made between nonce words (coinages created for a single occasion) and terms that become established as neologisms.

Linguists study neologisms in fields such as lexicography, corpus linguistics, and sociolinguistics. Methods include tracking usage in large text corpora, dating the emergence of terms, and analyzing semantic shifts to assess novelty and diffusion. The form neologismem is purely a grammatical inflection; the underlying concept is discussed as neologismus or neologism in reference works.

Examples of widely adopted neologisms include terms born from technology and culture, such as has become common in many languages, and their localization or translation often preserves the notion of a recently coined expression.
