The series 4000 Essential English Words (Nation, 2018) targets this specific lexical gap. Widely circulated through educational communities on platforms such as VK (VKontakte), the series has become a staple resource for self-directed learners and classroom instruction. This paper evaluates the methodological framework of the series and its efficacy in promoting lexical competence.
