Linguoculturological study of actual neologisms of the conceptosphere ‘Environment’ in French in political and social contexts

Aim. The purpose of the research is to reveal the specificity of the French linguistic picture of the world in the process of the emergence of lexical novelties in the modern French language through linguocultural analysis of the most relevant expressions and collocations verbalising the conceptosphere ‘Environment’ in political and economic contexts. Methodology. The study was conducted based on the analysis of a corpus of contemporary French texts, including official documents, media sources, digital platforms, and lexicographic materials. The following methods were employed: contextual analysis, word-formation analysis, frequency analysis, and comparative analysis. Results. The study identified the main lexical-semantic and word-formation features of French neologisms within the conceptual sphere of “Environment.” It was established that neologisms are primarily formed through calques, affixation, and the lexicalization of syntagms, reflecting both global ecological trends and national cultural values. The findings demonstrate that environmental vocabulary is actively integrated into the French linguistic worldview, representing values such as sustainable development, collective responsibility, and ecological awareness. Particular attention was given to the role of French language policy in regulating borrowings and preserving linguistic and cultural identity. Research implications of the study lies in identifying the mechanisms of neologization in the French language through the lens of environmental vocabulary as a reflection of sociocultural change. The research reveals specific features of word formation, borrowing, and linguistic purism, illustrating how language shapes and codifies the values of sustainable development. The results are relevant to linguistic and cultural studies, sociolinguistics, and the theory of lexical innovation
