The article explores the differences in word generation from various semantic categories in native and foreign languages. The study analyzes how language proficiency, cognitive processes, and lexical organization influence the speed and accuracy of word retrieval. Special attention is given to the comparison of semantic fluency in a first language and a foreign language, highlighting the role of linguistic experience and vocabulary depth. The findings demonstrate that word generation is generally more efficient in the native language, while foreign language performance depends on proficiency level and semantic familiarity. The research contributes to a better understanding of bilingual and multilingual language processing.
