This study highlights the importance of optimizing the process of learning a new language through a comprehensive analysis of the core Spanish lexicon. A holistic ap- proach is proposed, addressing internal structural delimitation, semantic, morphological, and phonological complexity, as well as lexical networks and processing. The research exam- ines word frequency, lexical acquisition in academic contexts, conceptualization tasks, and the quantitative and qualitative profitability of vocabulary learning. It also discusses lexical centrality and the need for an interdisciplinary perspective. Practical tools such as lexical analysis, frequency indexes, lexical availability studies, and other complementary works are presented. Finally, the lexical nomenclatures used in the Chinese educational system are introduced as a comparative model, underscoring the relevance of corpora and lexicometric tools in the analysis and selection of fundamental vocabulary.
